The invention relates to a variable displacement lubricant vane pump (10) for providing pressurized lubricant with a pump outlet pressure (P0), with a static pump housing (22) comprising a pump housing body (23), a shiftable control ring (24) and a rotatable pump rotor (26) comprising several rotor vanes (27) rotating within the control ring (24), the control ring (24) being shiftable with respect to the pump rotor (26) to thereby vary the eccentricity of the control ring (24) with respect to the pump rotor (26) for controlling the volumetric pump performance. The vane pump (10) further comprises a control ring preload spring (36) preloading and pushing the shiftable control ring (24) into the high eccentricity direction (h), a pilot control chamber (42) causing the shiftable control ring (24) to move against the control ring preload spring (36) and being selectively pressurized with pressurized lubricant having an over-atmospheric pressure (PG), an electric adjustment valve (50) for selectively directing pressurized lubricant having the over-atmospheric pressure (PG) to the pilot control chamber (42), and a pressure relief channel (46) directly connecting the pilot control chamber (42) with atmospheric pressure (PA). The pressure relief channel (46) is provided with an automatically self-adapting flow control valve (60) with an effective valve opening area (x1, x2) being dependent on the control ring position to define the volume flow flowing through the pressure relief channel (46) to thereby adjust the hydraulic pilot control chamber pressure (PC) so that deviations of the pump outlet pressure (P0) from the set outlet pressure can be compensated.

F01M 1/02 - Lubrification sous pression utilisant des pompes de lubrification
The invention is directed to a variable displacement lubricant pump (10) for providing pressurized lubricant, comprising a static pump housing (14), a shiftable control ring (16) arranged within the pump housing (14) and radially confining a substantially cylindrical pumping chamber (20), an inlet chamber (22) and an outlet chamber (28) both being partially confined by the control ring (16) and located at opposite lateral sides of the control ring (16), and a lateral slide bearing (34) located at the outlet-chamber- sided lateral side of the control ring (16) and comprising a first lateral slide bearing surface (36) defined by the pump housing (14), a second lateral slide bearing surface (38) being opposite of the first lateral slide bearing surface (36) and being defined by the control ring (16), and a lateral slide bearing gap (40) defined between the two lateral slide bearing surfaces (36,38), wherein the control ring (16) is provided with a drainage channel (42) fluidically connecting the lateral slide bearing gap (40) with the inlet chamber (22). The drainage channel (42) according to the invention minimizes a lubricant leakage via the lateral slide bearing (34) not requiring any separate sealing element within lateral slide bearing (34). This provides a cost-efficient, reliable and efficient variable displacement lubricant pump (10).

AUTOMOTIVE ELECTRIC AUXILIARY UNIT WITH AN ELECTRIC MOTOR
The invention refers to an automotive electric auxiliary (10) unit with an electric motor (12), comprising - a static motor stator (14), - a rotatable rotor shaft (18), and - a rotatable motor rotor (16) co-rotatably fixed to the rotor shaft (18) and rotating about a rotor axis (20) and comprising a permanent magnetic rotor body (22), wherein the motor stator (14) comprises a stator coil (32) and a stator sheet pack (26) with numerous packed stator sheets (28) of which the parallel sheet planes (33) are not arranged in a cross plane (31) but are inclined with an angle of inclination (30) of at least 2° to the cross plane (31).
H02K 5/128 - Enveloppes ou enceintes caractérisées par leur configuration, leur forme ou leur construction spécialement adaptées à un fonctionnement dans un liquide ou dans un gaz utilisant des manchons d'entrefer ou des disques à film d'air
The invention is directed to a variable displacement lubricant pump (10) for providing pressurized lubricant, comprising a static pump housing (14), a shiftable control ring (16) arranged within the pump housing (14) and radially confining a substantially cylindrical pumping chamber (20), an outlet chamber (28) partially confined by a radial outside of the control ring (16), and a slide bearing (42) adjoining the outlet chamber (28) and shiftably supporting the control ring (16) within the pump housing (14), wherein the slide bearing (42) comprises a first slide bearing surface (44) defined by the pump housing and extending in a slide plane (P), and a second slide bearing surface (46) defined by the control ring (16). Because an outside projection area (A1) defined by the orthographic projection of an outside pressure surface (30) of the control ring (16) onto the slide plane (P) is smaller compared to a maximum inside projection area (A2-max) defined by the orthographic projection of an inside pressure surface (40) of the control ring (16) onto the slide plane (p), the variable displacement lubricant pump (10) according to the invention can be realized cost-efficiently and provides reliable and efficient pump operation.
