Definitions
- the invention relates to a control device for positive displacement pumps, especially for vane pumps, according to the preamble of claim 1. It contains a pressure chamber via a throttle device with a to a consumer connected outlet in connection. Next is an in a housing bore of displaceable flow control pistons is provided, its first end face with the pressure chamber connection Has. A second face of the flow control piston protrudes into a chamber with the outlet downstream of the Throttle device is connected.
- the flow control piston gives depending on one acting on the two end faces Differential pressure a connection from the pressure chamber to one Pump inlet channel free.
- the throttle device sits in the Pressure output of the pump and contains a control pin, the Control contour is designed so that together with a Throttle bore a changeable passage cross section results.
- One of the two elements is control pin and Throttle bore connected to the flow control piston and that other of the two elements is fixed to the housing.
- the invention has for its object a control device to create such an overshoot, d. that is, a brief increase in the delivery rate or Delivery pressure, with rapid acceleration starting from lowest speeds is prevented.
- Control device solved in that the control pin in an axial displacement range that the flow control piston not yet used for volume flow control is, has a thickened section, so that in this There is a minimal aperture cross-section. It is achieved that the pressure difference over the thickened area is larger and thus the flow control piston earlier, or faster with dynamic processes, emotional.
- control pin with its thickened section can be easily removed establish if the control pin with the flow control piston connected and the throttle bore is fixed to the housing and the thickened section is cylindrical.
- the thickened one can better fine-tune the control characteristic Section have a frustoconical contour. It is advantageous if the larger diameter of the Truncated cone on the first face of the flow control piston is arranged. This allows the characteristics of the Control process, the control speed, very finely tuned become.
- the invention is based on two in the Drawing of illustrated embodiments of the invention explained in more detail.
- the vane pump shown and described represents only one application example of the invention Control device. Instead, can also a roller cell pump or another positive displacement pump a control device according to the invention.
- a drive shaft 3 In a housing 2 closed by a cover 1 a drive shaft 3 is mounted.
- the drive shaft 3 carries a rotor in the usual way on a spline 4th
- a pressure plate 7 is located on the Pump package consisting of rotor 4, blades 5 and cam ring 6 on.
- Another pressure plate 8 is due to the force a spring 10 on the other side of the pump package.
- the wings 5 close delivery chambers, not shown between them, which is connected to a suction port 11 stand.
- the extracted pressure oil emerges from the delivery chambers via pressure openings, also not shown the pressure plate 8 in a pressure chamber 12.
- the pressure chamber 12 has part-ring-shaped channels 13 and 14 with under wing spaces 15 and 16 connection. This makes it possible the wings 5 passing through the pressure zone to the outside to press into the cam ring 6.
- a flow control piston 21 of the flow control valve 18 controls one in a known manner with a control collar 22 Inlet channel 23 of the pump.
- the control collar 22 In the drawn starting position the control collar 22 is under the load of a spring 24 at the throttle device 20.
- the inlet duct 23 is closed by the tax authority 22.
- a closure element 25 for example a pipe screw connection, that with a consumer, for example one Power steering, is connected.
- An inlet channel 26 closes the pressure chamber 12 to the bore portion 17A on.
- the throttle device 20 contains a control pin 27, which is firmly connected to the flow control piston 21 and one Throttle bore 28, which is arranged on the closure element 25 and is thus firmly connected to the housing 2.
- the two elements of control pin 27 can have the same effect and throttle bore 28 each with the other elements Housing 2 and flow control piston 21 may be connected.
- the control pin 27 has one at its free end Contour on which the speed-dependent influence on the allows the consumer-directed flow.
- Embodiment contains this contour essentially cylindrical end portion 30 to which a conical Section 31 and a section 32 with the smallest cross section connect.
- a thickened section 34 of the control pin 27 Between this section 32 and one first end face facing the throttle device 20 33 of the flow control piston 21 is according to the invention a thickened section 34 of the control pin 27.
- the thickened Section 34 extends over such an axial Length that when the flow control piston 21 no volume flow control by a distance corresponding to this length he follows. This means that after a such shift still no connection between that of of the pressure chamber 12 coming inlet channel 26 to the inlet channel 23 exists.
- the thickened Section 34 has a cylindrical contour.
- the thickened section 35 has a frustoconical contour. It is the larger diameter of the truncated cone on the first End face 33 of the flow control piston 21 is arranged. This is particularly advantageous because it is the characteristic of the Control process, the control speed, very finely tuned can be.
- a receiving the spring 24 of the flow control piston 21 Room 36 stands over a control line indicated by dashed lines 37, an annular groove 38 and a throttle point 40 with a Outlet 41, which is arranged on the closure element 25 is connected.
- the annular groove 38 and the throttle point 40 are omitted.
- the Room 36 is on one side by a second end face 42 of the flow control piston 21 limited.
- the control device works as follows:
- the entire flow of the pump initially flows through the Inlet channel 26 in the bore section 17A.
- the flow flows on the end face 33 of the control collar 22 over to the outlet 41.
- the flow flows through the drawn cross section between the control pin 27 and the throttle bore 28. This adjusts due to the resulting pressure drop in the flow control piston 21 slightly to the left, but the tax office 22 still does not begin with the opening of the inlet channel 23.
- By the very small throttle cross section between the thickened Section 34 and the throttle bore 28 is formed a large pressure difference across the throttle device 20 and thus above the flow control piston 21. This large pressure difference forces an accelerated movement of the flow control piston 21. This in turn leads to faster Response of the control mechanism so that an overshoot and excessive delivery is prevented.
