Abstract: A variable displacement vane pump with electronic oil pressure control provides efficient pumping of engine oil precise regulation of engine oil pressure. The variable displacement oil pump includes a rotor supported in a housing for rotation about an axis of rotation and a slide ring movably supported in the housing. A plurality of vanes extends between the rotor and the slide ring to define a plurality of variable displacement pumping chambers. An electronic drive mechanism is configured to position the slide ring with respect to the axis of rotation, and a controller is configured to drive the electronic drive mechanism for selectively positioning the slide ring to adjust an eccentricity of the slide ring relative to the axis of rotation such that the displacement of the pumping chambers is varied.

Abstract: A belt drive arrangement for an auxiliary unit of a motor vehicle includes, but is not limited to a belt pulley for receiving a drive belt, a shaft of the auxiliary unit that can be driven with the torque of the belt pulley, and a clutch device for the releasable torque transmission between the belt pulley and the shaft of the auxiliary unit. The clutch device includes, but is not limited to an electromagnet and a spring element. The spring element is preloaded in such a manner that the clutch in a currentless state of the electromagnet is closed.

Abstract: An adjustable vane cell pump is provided having a rotor, which includes, but is not limited to bearing slots extending in radial direction, in which cane plates displaceable relative to the bearing slots are arranged. The vane cell pump further includes, but is not limited to an adjustable slide having a substantially cylindrical inner surface. The rotor is configured in order to driveably rotate about a rotary axis within the slide. The vane plates bear against the inner surface of the slide, and the slide further includes, but is not limited to a first and a second areal end face, as well as recesses, which outer-circumferentially extend parallel to the end faces.

Abstract: A variable displacement vane pump includes, but is not limited to inlet and outlet ports in a pump body, a drive shaft rotatably mounted in the pump body, a rotor driven by the drive shaft and radially extending vanes slidably disposed in the rotor. A slide is pivotally disposed on a pivot and has a central axis eccentric to the axis of the rotor. Chambers are defined by the rotor, the vanes and the slide that are successively connected to the inlet and outlet ports. A resilient member is pivotally engaged with the slide and acts on the slide to urge the slide in one direction.

Abstract: A pump is provided for a lubricating system of a combustion engine that includes, but is not limited to a housing and a lid that together define a pump hollow space in which a pump mechanism for the pumping of lubricant of the lubricating system is arranged. The pump hollow space includes, but is not limited to at least one intake opening and at least one discharge opening. The pump additionally includes, but is not limited to a regulating valve for regulating a flow of the lubricant through the pump, which is integrated in the lid.

Abstract: An oil pump module is provided that has an oil pump module housing. The oil pump module is situated in an oil pan of an internal combustion engine below a crankshaft. Moving parts of an oil pump and an angular momentum balance shaft are situated in the oil pump module housing. A rotor of the oil pump is situated on a rotor shaft, which is separate from the angular momentum balance shaft, in the oil pump module housing. The rotor shaft is mechanically connected via a spur gear transmission in the oil pump module housing to the angular momentum balance shaft.

Abstract: A multifunction plug connector of an oil pan of a vehicle is provided having connection to a wiring harness of the vehicle outside the oil pan. Inside the oil pan, the multifunction plug connector has a supply line cable to an electronic component. The electrical component inside the oil pan is connected via an oil-tight feedthrough through the wall of the oil pan and via a plug connector situated outside the oil pan on a wall to the wiring harness of the vehicle. The plug connector has plug contacts or plug sockets for this purpose. Inside the oil pan, the multifunction plug connector has multiple separate supply line cables to multiple electronic components, which are connected to an engine control unit via the multifunction plug connector and the wiring harness.

Abstract: A lubricant circuit includes, but is not limited to a lubricant pump, which is connected on the suction side to a reservoir and on the pressure side to a distributor, at least one lubricating point, which is connected to the distributor and a return leading to the reservoir, and an electronic control unit, which is set up to regulate the output pressure of the lubricant pump by reference to the temperature of the lubricant.
