Definitions

  • the invention relates to a magnetic pump for an auxiliary unit of a vehicle having an inlet and an outlet, an electromagnet having a translationally movable armature, a core, a coil and a yoke, an axial piston which is movable up and down in a cylinder, a first check valve, which is biased against the axial piston and a second check valve, which is biased against an outlet opening of the cylinder and a method for controlling a magnetic pump for an auxiliary unit of a motor vehicle, wherein a coupled to an armature of an electromagnet axial piston by an alternating energization of the Spool is moved up and down in a cylinder for conveying a fluid from the inlet to the outlet.
  • Such magnetic pumps are used, for example, to provide the pressure for the hydraulic adjustment of a valve spool of a coolant pump driven by a belt pulley, the volume flow of which can be regulated in this way.
  • an armature of the electromagnet and with this armature an axial piston, which has an axial through-hole, in a cylinder moves up and down in these pumps.
  • the through-bore is closed at its end facing the outlet by a check valve, which is also arranged in the cylinder.
  • the ejection movement takes place against another check valve which bears against an outlet of the cylinder.
  • an intermittent pumping by energization and Brobestromung or partial energization of the coil of the electromagnet arises.
  • Such an electric fluid pump is for example from the EP 0 288 216 A1 respectively.
  • Another solenoid pump or vibration tank pump is used in the WO 2011/029577 A1 disclosed.
  • the axial piston is made in two parts and has an axial through hole, wherein the first Axialkolbenteil connected to the armature or is integral with the armature and can be lifted from the second Axialkolbenteil, wherein in the lifted state via a gap between the two Axialkolben inconvenience between the inlet and the outlet is the fluidic connection, a flow through the pump and in particular a return flow from a to be filled by the pump pressure pressure chamber is possible without having to use an additionally controlled valve.
  • a fail-safe position for example, for the application of a controlled via a slider coolant pump is created.
  • a compression spring is arranged between the first Axialkolbenteil and the second Axialkolbenteil, which ensures that the armature is in its fully retracted position in case of failure of the electromagnet and on the other hand dampens the stop of the two Axialkolbenmaschine upon movement of the armature from this position.
  • the second Axialkolbenteil is due to the compressive force of a second compared to the first compression spring, stronger compression spring at full return of the armature against the stop and in the operating positions during pumping operation of the armature against the first Axialkolbenteil. This ensures that when moving from the fully retracted position of the armature first, the gap between the first Axialkolbenteil and the second Axialkolbenteil is closed and then the axial piston is displaced as a unit during the actual pumping movement.
  • the stopper is formed on a first insert housing part, whereby the production of the entire outlet housing is simplified.
  • the first check valve is biased by a first spring against the second Axialkolbenteil and is moved with this in the direction of the outlet and the second check valve is biased by a second spring against the outlet opening of the cylinder. So on the one hand, a sufficient pressure build-up in the ejection movement ensured and on the other hand allows subsequent filling of the cylinder in pumping operation.
  • the first Axialkolbenteil is advantageously connected via a bore in the armature to the armature, whereby the joint movement is ensured. Nevertheless, the structure and the assembly is easy, since the attachment can be made by screwing or pressing and only the first Axialkolbenteil must be performed.
  • the effective diameter of the second Axialkolbenteils is greater than the effective diameter of the first Axialkolbenteils.
  • the inlet and the outlet are arranged at axially opposite ends of the magnetic pump, wherein the armature is arranged on the side of the inlet and the check valves and the second Axialkolbenteil are arranged on the side of the outlet.

This simplifies the production and delimitation of the individual hydraulic chambers in the outlet housing.
  • the spring of the first check valve is designed such that the first check valve follows the second Axialkolbenteil, when it moves in the direction of the inlet delayed. As a result, a sufficient filling of the cylinder for fluid delivery is ensured.
  • a transverse bore is formed in each of the first axial piston part and the core on the inlet side region.
  • shocks between the moving parts or from the movable parts to their stops thereby preventing that at the second Axialkolbenteil in the region of the stopper and / or in the Area of the system on the first Axialkolbenteil and / or between the armature and the core elastic damping elements are arranged.
  • an annular, directed to Einlegegeophuseteil recess is formed on the second Axialkolbenteil, which dips into an axial end of the cylinder when fully displaced in the direction of the outlet anchor.
  • This recess serves in the movement of the axial piston in the direction of the outlet as a hydraulic damping chamber, which prevents a collision of the second Axialkolbenteils on the cylinder wall.
  • annular recess on the side of the inlet to an inlet housing of the magnetic pump is formed, into which an annular inlet facing corresponding projection of the armature with complete recovery of the armature dips.

  • the second axial piston part 64 bears against the radial constriction 70, which serves as a stop 76 for the second axial piston part 64, with a radial expansion surface 75.
  • the effective diameter of the first Axialkolbenteils 38 is smaller than that of the second Axialkolbenteils 64.
  • an elastic damping element 78 is arranged in the area of the stop 76 in turn.
  • At the end 30 facing the end of the second Axialkolbenteil 64 is hollow cylindrical and protrudes into a cylinder 82 in which the hollow cylindrical part of the second Axialkolbenteils 64 is guided and which is arranged radially within the gap 74.

  • a second insert housing part 100 is arranged, which forms the cylinder 82 and its axial boundary wall 102 facing the outlet 30 separates the space 74 from an outlet space 104, which leads to the outlet 30 and in which the second check valve 96 is arranged.
  • this boundary wall 102 in turn, at least one opening 106 is formed, via which there is a continuous fluidic connection between the intermediate space 74 and the outlet space 104.
  • a compression spring 108 which is stronger than the compression spring 62 and which surrounds the cylinder 82.
  • This compression spring 108 is supported with its first axial end against the intermediate wall 102 and with its other axial end against the extension surface 75 of the second Axialkolbenteils 64 so that it is loaded in the direction of the first Axialkolbenteils 38.
  • the inlet 26 is fluidically connected to the outlet 30 via the through-bore 40, the gap 67, the piston space 72, the openings 80, 106 of the inserts 68, 100 and the outlet space 104.
  • the height and duration of the partial energization is selected so that the force of the first compression spring 62 is overcome, so that the first Axialkolbenteil 38 abuts against the second Axialkolbenteil 64 and thus the gap 67 between the two Axialkolben constitution 38, 64 closed via the damping element 66 is, so that the two Axialkolbenmaschine 38, 64 move in operation as a unit.
  • the second stronger compression spring 108 is not compressed at Crystalbestromung because their force is greater than that of the electromagnet 10 at Generalbestromung.
  • the force acting on the armature 22 in the direction of the outlet 30 is greater than the sum of the counteracting forces, ie the spring forces of the springs 62, 108 and the possibly existing acting on the components hydraulic forces. Accordingly, the axial piston 38, 64 is moved as a unit in the direction of the outlet 30. With the axial piston 38, 64, the first check valve 86 is moved in the cylinder 82 toward the outlet 30, so that in the cylinder 82, a pressure builds up, which eventually causes the second check valve 96 opens against its spring force and fluid from the cylinder 82 in the outlet space 104 flows.
  • the axial piston 38, 64 moves as a unit in the direction of the inlet 26. Due to its inertia and the resulting in this movement in the now closed by the second check valve 96 cylinder 82 negative pressure follows the first check valve 86th the axial piston 38, 64 significantly delayed because its spring force for a permanent contact with the axial piston 38, 64 is not sufficient. During this movement, fluid is also sucked through the axial passage bore 40, 83 into the cylinder 82, thus flowing through the gap between the first check valve 86 and the axial piston 38, 64 into the cylinder 82.
  • Another hydraulic damping chamber becomes effective in the movement of the second Axialkolbenteils 64 in the direction of the outlet 30.
  • the radial extension surface 75 of the second Axialkolbenteils 64 is bent at its outer periphery in the direction of the cylinder 82 in such a way that between the hollow cylindrical part, which can be driven into the cylinder and this surface an annular recess 110 is formed. In this engages the inlet 26 facing the end of the cylinder 82 during the movement of the axial piston 38, 64 in the direction of the outlet 30, so that the existing fluid in the recess 110 can escape only through gaps and thus dampens the movement.
  • the magnetic pump according to the invention has a very low wear and provides a simple and quick pressure equalization between inlet and outlet. At the same time, with appropriate use of the magnetic pump, this function of the provision of the Ankers can also be used as a fail-safe function. Thus it can be dispensed with a separate valve.
