Definitions

the present invention relates to an electric actuator.
the invention relates to an electric actuator with two stable active positions and a rest position, comprising a movable armature connected to a member to be actuated, such as a valve motor valve motor vehicle.
actuators of this type in which the armature is arranged in the air gap separating a first and a second electromagnet placed opposite one another and is associated with two elastic members arranged on either side of this frame, to stress the latter in the rest position, the electromagnets being connected to means feeding them, in order, in cooperation with the elastic members, to move and alternately maintain this armature in active positions stable against the first and second electromagnets.
the operating principle of such an actuator is based on the use of a harmonic oscillating system controlled by two independent electromagnets.
Each engine valve is connected to an armature balanced between two compression springs.
an initialization phase which consists, for example, in ordering alternately the electromagnets at the natural frequency of the armature-organ system to be actuated, the armature is glued against one of the electromagnets of the actuator depending on whether you want to keep the valve open or closed.
Each electromagnet is controlled individually.
the electromagnet connection wiring also degrades the reliability of the actuator.
the object of the invention is therefore to solve these problems.
the invention relates to an electric actuator with two stable active positions and a rest position, including a frame mobile connected to a member to be actuated, such as a vehicle engine valve automobile, the armature being arranged in the air gap separating a first and a second electromagnets placed opposite one another and being associated with two elastic members arranged on either side of this frame to stress this in the rest position, the electromagnets being connected to supply means of these, to, in cooperation with the elastic organs, move and alternately maintain this armature in stable active positions against the first and second electromagnets, characterized in that the means for supplying electromagnets are formed by a power source common of these controlling their food at the same time.
This figure shows an electric actuator with two stable active positions and one rest position, this actuator being designated by the general reference 1.
This actuator in fact comprises a movable armature designated by the general reference 2, which is connected to a member to be actuated such as for example a motor vehicle engine valve, designated by the general reference 3.
the frame is then placed in the air gap separating a first and a second electromagnet, designated by the references 4 and 5 in this figure, placed opposite each other.
the frame 2 is also associated with two designated elastic members by the general references 6 and 7 in this figure, and constituted for example by springs arranged on either side of this frame to stress this in the rest position.
the electromagnets are connected to power supply means of these designated by the general reference 8, for, in cooperation with the elastic members, alternately move and hold the armature 2 in stable active positions against the first and second electromagnets.
a position sensor designated by the general reference 9 is also associated with this frame, this position sensor being connected to the means supply 8 of the electromagnets to ensure correct control of the supply of these, that is to say cut or establish this supply when one wishes to pass the armature and therefore the valve between their stable positions.
the means for supplying the electromagnets are formed by a common power source of these driving at the same time their power supply, these electromagnets then being connected in parallel or in series across the common power source 8.
This structure allows a very significant reduction in the number of electronic power components and a simplification of the wiring used, with a very clear cost and reliability impact.
the rest position of the armature 2 is offset from the plane of equilibrium of the magnetic forces opposites of attraction of this generated by the electromagnets when these are powered.
the elastic organs constituted by the springs 6 and 7, can be symmetrical, while the electromagnets respectively 4 and 5, present an asymmetry so as to generate forces opposite magnetic attraction asymmetrical on the frame 2 to allow to this armature to move towards one of the electromagnets at the setting tension of these.
the electromagnets 4,5 can also be symmetrical, while the elastic members constituted by the springs 6 and 7 may exhibit an asymmetry so as to define a rest position of the armature offset from the plane of symmetry of the electromagnets to allow the armature to move towards one of these.
the armature is then closer to one of the electromagnets when energizing of the coils thereof, which allows its displacement towards this one.
magnetic shielding means can be associated with these electromagnets.
the initialization phase of this system then also consists of supply the electromagnets so as to bring the armature against one of them, either directly if the means of supply are capable of supplying strong currents to glue the reinforcement at once against the corresponding electromagnet, either indirectly by oscillation of the system by ordering it at its natural frequency.
this actuator has a certain number advantages over those of the state of the art insofar as the unique power supply means of the two electromagnets can be used in association with unique wiring means of these to these means, this which reduces the number of components used and simplifies connection from these electromagnets to these supply means in order to reduce the cost of this function and increase its reliability.
