Abstract: A seal arrangement for a vane cell pump of cartridge design which is configured such that it can be switched into multiple flows is described. The seal arrangement comprises a first seal which is arranged so as to run around the circumference of a side plate of the vane cell pump, and a second seal which is arranged so as to run around a shaft leadthrough which is provided in the side plate. The seal arrangement is distinguished by a third seal which, apart from at least one first fluid connection, shuts off at least a second fluid connection with respect to the at least one first fluid connection within a region which is configured between the first seal and the second seal.

Abstract: A pump having a stroke ring which has an axial recess, a rotor which is received in the axial recess so as to be rotatable relative to the stroke ring, wherein the rotor has radial recesses in which delivery elements are displaceable received as viewed in a radial direction, a side plate which closes off the axial recess on a first side, a pressure plate which closes off the axial recess on a second side, wherein the pressure plate has at least one opening, wherein a pressure region of the pump is fluidically connected to external surroundings of the pressure plate through the at least one opening, and wherein at least one fluid path is provided from the pressure region of the pup into an under-vane region of the delivery elements, and a cold-start plate which is preloaded against the pressure plate by means of a spring element such that, at least when the pump is at a stand-still, the cold-start plate closes the at least one opening in the pressure plate to the external surroundings of the pressure plate.

Abstract: A pump has a suction region, a pressure region, and a pressure space which has an outflow region. A rotor is connected to a shaft in which rotor delivery elements are displacably received. The rotor has expelling regions connected to the pressure region by way of a first fluid path. A cold starting device is prestressed into a first functional position to shutoff a second fluid path from the pressure region to the pressure space, and is configured to be displaced counter to the prestress into a second functional position to open the second fluid path. The cold starting device is arranged in its second functional position at least in regions with a relief face which faces away from the pressure region in a relief receptacle. The relief face is loaded during operation of the pump with a pressure being smaller than a system pressure in the outflow region.

Abstract: A pump, preferably a vane cell pump for supplying a transmission with oil, includes a pump housing and a rotating group which is disposed inside the pump housing. The rotating group includes a side plate that may be mounted inside the pump housing in such a manner as to produce, at least temporarily, an axial gap between the side plate and the pump housing. A shaft is mounted inside the pump housing and a radial packing ring is located in a recess around the shaft. The packing ring seals off the rotating group towards the exterior radially on the pump housing and radially on the shaft using a sealing lip.

Abstract: The present invention relates to an electromagnetic valve of a cartridge-type construction comprised of a magnetic core, a magnetic armature (12) with valve closure member (4), and a valve seat member which form an operative unit in a valve housing, the said valve housing including a closed sleeve portion (1) which has a collar (17) on the opposite open end area for attachment in the valve housing. Inserted telescopically into the open end area of the sleeve portion (1) is a sleeve-shaped annular part (2) which carries the valve seat member (3) and aligns the latter concentrically in relation to the valve closure member (4) to form an operative unit.
