Abstract: A method for manufacturing a component with moulded-on seal, in particular a pump component. The component is laid in an injection-moulding tool, then a sealing material is injected from an injection gate into the injection-moulding tool and fills a cavity on one side of the component. Sufficient sealing material is injected for a part of the sealing material to pass from the cavity, via an overflow channel connected to the cavity, into an overflow chamber which is provided inside the contour of the component. A component can includes the moulded-on seal.

Abstract: An oil supply system for a machine, such as for a power unit of a motor vehicle, with a module body made of plastic including a collection tank which is divided into a prechamber and a main chamber. A predelivery pump can extract oil from the prechamber and pump it into the main chamber, a main delivery pump can extract oil from the main chamber and pump it to the machine, and a return line can return oil from the machine to the prechamber and/or the main chamber. A power unit for a motor vehicle can include such an oil supply system, wherein a predelivery suction opening is arranged on the floor of the prechamber and a main delivery suction opening is arranged on the floor of the main chamber, and the power unit is configured to be mounted in the motor vehicle with an orientation such that a line running through the two suction openings is arranged approximately parallel to the transverse axis of the vehicle.

Abstract: A rotary vane pump includes a pump housing, a stator, a rotor, a plurality of vanes which are accommodated in the rotor so as to be displaceable in the radial direction, so that they delimit a plurality of pump chambers between themselves, the stator and the rotor. A radially inner cam surface is provided, against which the vanes rest, wherein secondary chambers are delimited in the radial direction between the cam surface and the rotor and in the circumferential direction between the vanes, with a suction inlet and a pressure outlet being assigned to the secondary chambers.

Abstract: A gear-change selector module for a gearshift of a motor vehicle has a movable element and a shift fork having a carrier arm which engages in a recess of the movable element. The recess has two actuating faces which cooperate with carrier faces of the carrier arm. Viewed in a section running through the centre axis of the movable element and the centre axis of the recess, the actuating faces are each convex in a first portion extending from the centre axis in the direction of the outside of the movable element. Furthermore, viewed in a section running through the centre axis of the movable element and the centre axis of the recess, the carrier faces each extend in a first portion from radially outside the movable element up to the centre axis of the movable element, and in a second portion from the centre axis in the direction of the free end of the carrier arm. The carrier faces are convex in the second portion.

Abstract: A piston for a gear-change selector module of a gearshift has a piston body, at least one sealing element, and a cap which is attached to the piston body by means of a clip connection. Furthermore, the sealing element is here attached to the piston body by means of the cap. Also a gear-change selector module with a piston, and a method for mounting a piston, are provided.

Abstract: A gear pump having a pump housing, a rotatably mounted drive shaft extending into the pump housing, and a rotor of a drive motor. The rotor is attached in a rotationally fixed manner on the drive shaft, and at least one drive gearwheel which is arranged in a rotationally fixed manner on the drive shaft in the pump housing. At least one gearwheel is driven by the drive gearwheel, wherein the drive gearwheel is fixed axially on the drive shaft. The drive gearwheel together with the pump housing forms an axial bearing for the rotor.

Abstract: An electromagnetic actuating device for a torque transmission system includes a shell arranged around an axis X, the shell being fixed relative to the axis X. The shell includes walls defining an annular cavity which houses a coil and at least partially a plunger which is able to move axially along the axis X to actuate a coupling device.

Abstract: A sliding-vane pump includes a housing in which a cylindrical fluid chamber is formed, and a conveyor rotor which is rotatable in the fluid chamber and is guided on a circumferential wall of the fluid chamber. In the fluid chamber, the conveyor rotor delimits at least one conveyor chamber having a volume which is variable by rotation of the conveyor rotor, and a drive motor having a rotor which is attached rotationally fixedly on a drive shaft. The conveyor rotor is arranged positionally fixedly on the drive shaft and the drive shaft is radially mounted in the housing by means of the conveyor rotor.
