Definitions
- the invention relates to an engine control valve.
- This type of valve can, for example, equip a gas supply circuit of a vehicle engine, to regulate the flow of gas EGR (Exhaust Gas Recirculation) in a loop for puncturing a portion of the exhaust gases. exhaust at engine output, for reinjecting upstream of said engine.
- EGR Exhaust Gas Recirculation
- the operating principle of this type of valve is based on the controlled rotation of a flap, which can pass from a full open position to let the fluid to a closed position to block this passage.
- the invention relates to a fluid circulation valve whose opening mechanism has been improved.
- An engine control valve therefore has a flap, which is pivotally mounted on an axis of rotation, so that said axis separates the flap into a first portion and a second portion. It should be noted that no physical limit materializes the boundary between the first and second part of the component. It is assumed that these two parts are fictitiously separated by a plane passing through the axis of rotation of the flap and intersecting said shutter perpendicularly.
- the internal structure of the valve in which the flap is mounted has a seal. When said flap is in a closed position, the first portion of said flap comes into contact with this seal, while the second portion is flush with said seal, leaving a gap of a few tens of millimeters with said seal.
- FIG. 1 is a diagram giving the mass flow rate of the gas as a function of the opening angle of the valve flap.
- the curve 100 giving the mass flow rate of the gas passing through the valve as a function of the flap opening angle, firstly shows a first very steep zone 101 corresponding to a sudden increase in flow over an angular range of between about 0 and 5 °, su ivie of a uxie me zone 102 assi mila ble to a plateau and corresponding to an angular range between about 5 ° and 10 °, said cou rbe 100 ending in a third zone 103 approximately linear, showing a substantially proportional progression of said flow as a function of the opening of the flap over an upper angular range at about 10 °.
- the two other curves 105, 106 shown in the diagram show a linear variation of the mass flow rate of gases passing through other types of valves, as a function of the opening angle of the flap of said valves, and this over the entire angular opening range. possible of said flap. These two curves materialize the variation of the gas flow that would be desirable to observe with a valve according to the invention.
- An engine control valve according to the invention has a seam having undergone a structural modification, in order to mimic the gaseous flow rate for the small opening angles of this shutter.
- the gas flow rate passing through said valve will be linear over the entire angular opening range of the flap, thus eliminating the abrupt rise phase of this flow observed for very small opening angles, as well as the stagnation phase of the flap. this flow after this sudden rise.
- a valve according to the invention thus ensures a gradual increase of the gas flow, smoothly and smoothly, and therefore offers better control of this flow, compared to that proposed by the existing valves.
- the subject of the invention is an engine control valve, having a body delimiting an internal duct and comprising a flap provided with an axis of rotation separating said flap in a first portion and a second portion, wherein said flap is pivotally mounted in a led it conducts between a fully open position allowing passage of the fluid in the conduit and a closed position preventing said passage, and for which the first portion abuts against a seal, said seal being provided with an opening for the passage gases in the duct.
- the seal has an extension protruding into the opening, so as to partially mask said opening.
- the purpose of such an extension of the seal is to reduce the section of passage of the gases as soon as the flap pivots to open, so as to soften the rise of the flow of gas on the first degrees of opening of said flap, and therefore to eliminate the phase of stagnation following this sudden rise in flow.
- the seal may for example be annular or rectangular in shape, the opening of said seal corresponding approximately to the gas passage section in the conduit.
- the term "approximately" means that the opening may be slightly smaller than the gas passage section in the conduit, without changing the flow characteristics of said gases in the valve.
- the extension which is intended to reduce the size of the original opening of the seal, may be constituted by an added piece that is secured to the seal, or may be manufactured at the same time as said seal, to form with it only one and the same room.
- the first part of the flap is shaped to ideally bear against the seal, to ensure a completely sealed closure of the valve.
- the extension may form a surface extending exclusively in a plane parallel to the joint.
- the extension can be used to extend only in the plane of the point.
- the extension can form a salient surface exclusively in the opening.
- the extension may form a non-flexible surface.
- the extension may define a protruding edge in the aperture and extending in a direction intersecting with two contiguous edges of the aperture.
- the extension decreases the opening of the joint by at least 15%. Indeed, it is necessary that this imin ution opening is large enough to obtain a certain proportionality between the degree of opening of the shutter and the value of the flow, especially for the first degrees of opening thereof. But this iminution should not be too high, under penalty of creating a strangely in the valve, which could be detrimental and could compromise the flow conditions of gas in the valve.
- the resulting opening of the seal in the presence of the extension, has a smoothed contour.
- the resulting reduced opening must not have a rugged contour, made of points, raised edges or hollows in ang le, likely to locally disturb the gas flow in the van ne, creating tou local areas or heterogeneous areas of pressure.
- the resulting opening of the joint, in the presence of the extension, may have the overall shape of a polygon having at least five sides and three consecutive right angles.
- the resulting opening of the joint, in the presence of the extension may have the overall shape of a polygon having four sides and three consecutive right angles.
- the opening is rectangular, the extension being triangular and originating on at least one edge of the seal surrounding said opening.
- This is a simple form of extension to manufacture, and is perfectly suited to the problem to be solved.
- the extension has the shape of a right triangle and is connected to at least two edges of the seal surrounding the opening. In this way, the extension contributes to reducing the opening of the joint, without creating fractures or asperities likely to affect the gas flow in the valve.
- the extension and the joint constitute one single piece.
- the resulting seal can be manufactured in a single operation with precision and control.
- the first part when the flap is in a closed position for which it closes the duct, the first part must interact closely and ideally with the seal to ensure a full seal.
- This removal of material in the first part of the shutter allows the extension of the seal to be placed in an optimized manner against said first part when the shutter closes the conduit of the valve.
- Such a configuration for which the extension of the opening and the first part of the shutter cooperate closely solves in an optimized way the problem l ied to the sudden rise of the gas flow for the small opening angles of the flap.
- the extension may engage, when the flap is in the closed position, a plane contact with the first part of the flap.
- the seal has an extension intended to interact with the second part of the flap.
- the second part of the flap is caused to come flush with the joint extension, when the flap is in a closed position, leaving a minimum clearance of a few tenths of a millimeter. It is assumed that the joint is generally flat and thin.
- this extension corresponds to the second portion of the seal described in the detailed description.
- the extension of the seal has a secondary opening.
- the secondary opening located in the extension of the seal is intended to generate a depression behind the second part of the flap, which then tends to be sucked by said depression.
- the movement initiated by this second part being opposite to that of the first part, it plays a compensating role to allow said shutter not to deform and maintain a linear resulting profile, to ensure a good seal when it is in a closed position.
- the extension of the seal has a rib, the secondary opening being made in said rib.
- the secondary opening is made within this rib will increase the vacuum surface thus created by said opening, and will contribute to ensure a particularly tight closure of the flap.
- the secondary opening occupies a central position in the extension.
- the valves according to the invention have the advantage of offering good control of the gas flow over the entire opening range of the flap, notably by proposing a linear and regular rise of the gas flow over a reduced angular opening range of the flap. .
- the valves according to the invention have the advantage of being more efficient than the existing control valves, thanks to this improved control of the gas flow, while remaining of a constant bulk and easy to manufacture.
- FIG. 1 already described, is a diagram giving the mass flow rate of the gas passing through a control valve of the state of the art as a function of the opening angle of its flap

- a gas circuit of a motor vehicle engine comprises an upstream gas supply portion of said engine, in which fresh air circulates, and a downstream exhaust part in which flue gases circulate to be evacuated. out of the vehicle.
- a gas circuit comprises at least one EGR loop (English Exhaust Gas Recirculation) joining the downstream exhaust portion to the upstream feed portion, to allow to mix exhaust gas to the air incidental expenses. Since these EGR loops must not be permanently open during all phases of engine operation, they are each equipped with an EGR valve for regulating the flow of exhaust gases flowing in the loop considered.
- An EGR valve comprises a gas circulation duct and a shutter 1, pivotally mounted on an axis 2 of rotation, and able to move between a closed position for which it prevents the passage of the exhaust gas, and a fully open position for which it authorizes this passage with a maximum flow.
- the control mechanism of the flap 1 makes it possible to fix said flap 1 in any intermediate position situated between these two extreme positions.
- the flap 1 is mounted on the axis 2, so that said axis 2 separates said flap 1 into a first portion 3 and a second portion 4.
- Said portions 3,4 are flat and low thickness, and are located in continuity with one another. Preferably, they constitute one and the same piece.
- These two portions 3,4 have an identical width, said width constituting their dimension taken along the axis of rotation 2, while the first part 3 has a length less than that of the second part 4, the length of which represents their dimension taken along an axis perpendicular to said axis 2 of rotation.

- this connecting piece 6 in contact with the support part 5, ideally extends the second portion 4 of the shutter 1, having the same thickness at their junction plane 7 , the thickness of this connecting piece 6 decreasing progressively away from said junction plane 7, in a direction perpendicular to this plane 7.
- the junction plane 7 is parallel to the axis of rotation 2 of the shutter 1.
- the dimensions of the support part 5 are greater than those of the connecting piece 6 in its contact, so that the thickness of the U-shaped peripheral part of the first part 3 of u flap 1 corresponds to the thickness of this support part 5.
- the second part 4 of the flap 1 and the connecting piece 6 constitute a single piece.
- the concept of "connecting part” was introduced in order to describe part 1 as precisely as possible, without suggesting that this part is necessarily independent and autonomous. It is the same for the two parts 3, 4 of the shutter 1, which correspond to the two parts of the shutter 1 situated on either side of the axis, but which do not necessarily differ in a marked physical limit. and visible.
- the gasket 8 is a flat piece, of small thickness, and which has a generally rectangular shape, to distinguish a first portion 9 and a second portion 10, said second portion 10 being termed extension in the claims.
- the first portion is rectangular 9 and extends in a direction perpendicular to the longitudinal axis of said seal 8. In other words, the longitudinal axes of the gasket 8 and the first portion 9 are perpendicular.
- This first portion 9 has an opening which, for a seal of the state of the art, is rectangular and whose dimensions are similar to those of the gas passage section in the conduit of the valve.
- this opening li has been reduced by means of an extension 12 of the seal, which projects inside said opening 11, said extension 12 having the shape of a right triangle.
- the two mutually perpendicular sides 13,14 of this extension 12 are in contact with two perpendicular edges 15,16 delimiting the opening, each of said sides 13,14 having a length less than the length of the edge 15,16 on which it take support.
- this extension 12 and the seal 8 are constituted by the same material and form a single piece, said sides 13,14 and said edges 15,16 being in perfect continuity without being distinguishable.
- the resulting opening 11 thus has an end 17 of constant width over a short length, said width decreasing progressively over the rest of the length of said opening 11, away from said end 17 of constant width, to reach a minimum value. not zero.
- the second portion 10 of the gasket 8 is rectangular and extends in a direction perpendicular to the longitudinal axis of said gasket 8. In other words, the longitudinal axes of the gasket 8 and the second portion 10 are perpendicular.
- This second portion 10 is generally solid, and has a recess 18 in the form of a rectangular groove, extending parallel to the second portion 10 of the gasket 8.
- This groove 18 occupies a central position in the second portion 11 of the gasket 8
- This second portion 10 has a secondary opening 19, similar to a circular orifice, said orifice 19 being placed in the center of the groove 18.
- the dimensions of this orifice 19 are significantly smaller than those of the opening 11 of the first portion 9, the ratio between their area may vary from 10 to 20.
- the connecting piece 6 of the shutter 1 has undergone a material removal, the contour of which is triangular and has the same dimensions as those of the extension 12 of the gasket 8. In this way , said piece of l ison 6 has an oblique edge 20.
- the first part 3 of the flap 1 can be placed against the first portion 9 of the seal 8, so that that the extension 12 of the joint 8 can be expected to lodge in the trace of the ad ite first part 3 generated by this removal of material.
- the flap 1 is mounted in the valve so that the first portion 3 cooperates with the first portion 9 of the seal 8, and so that the second portion 4 cooperates with the second portion 10 of the seal 8 , the axis of rotation 2 of said flap 1 embodying the separation between the two portions 9, 10 of the gasket 8.
- the flap 1 When the flap 1 is in a closed position, the first part 3 comes into contact with the first portion 9 of the gasket 8, so that the extension 12 of the gasket 8 is in contact with said first portion 3 at the location generated by the removal of material.
- the second portion 4 of the flap 1 comes flush with the second portion 10 of the joint 8, leaving a gap of a few millimeters.
- the secondary opening 19 made in the second portion 10 of the seal 8 makes it possible to create a negative pressure so as to aspire the second portion 4 of the flap, in order to compensate for the movement of the first portion 3 of the flap 1.
- the gases located upstream of the shutter 1 exert a pressure on the first part 3 of said shutter 1, which tends to be pushed back and thus to slightly open, allowing a small fraction of the gases.
- the depression contributes to moving the second part 4 of the shutter 1, in a direction which is opposite to that of the first part 3, allowing said shutter 1 to maintain a linear profile and thus ensure a good seal of the closure.
