Abstract:
An automotive hydraulic actuating system for actuating a movable vehicle part, like a roof part or a wheel suspension. The actuating system comprises a pump unit. The pump unit comprises a piston pump which has a pump rotor and an electric motor which has a motor rotor. The pump rotor and motor rotor are incorporated into a single common rotor. The rotor is a one piece item. The rotor is positioned inside a pump chamber around a pump stator of the piston pump. The pump stator provides a full support to the common rotor. Advantageously, without a separate motor stator, the pump unit has a more compact configuration. Additionally, the pump unit has an improved dynamic performance which contributes to a silent and reliable operation at a high rotational speed.

Claim (Index 18):
A pump unit for pressurising a hydraulic actuating system in particular for pressurising an automotive actuating system, like a convertible roof system, boot lid, hood cover system or wheel suspension of a vehicle, wherein the pump unit comprises a pump housing including a pump chamber for housing a piston pump and wherein the pump unit further comprises an electric motor for driving the piston pump,\n wherein the electric motor comprises:\n a motor rotor wherein the motor rotor comprises a longitudinal motor rotor body including several magnets at an outer surface, wherein the motor rotor body defines an axial axis; \n a field coil which is positioned opposite the magnets of the motor rotor body for rotationally driving the motor rotor body; \n wherein the piston pump comprises:\n a pump stator which is stationarily positioned inside the pump chamber, which pump stator has a longitudinal stator body, in which the pump stator body includes at least two channels serving respectively as an inlet or outlet channel; \n a pump rotor positioned around the pump stator body, which pump rotor has a pump rotor body which is driveable in a rotational direction about the axial axis, wherein the pump rotor body includes several cylinder holes for each receiving a piston which is slidable with respect to the pump rotor body in a radial direction; \n an eccentric ring positioned around the pump rotor body in which the eccentric ring is eccentrically positioned at an eccentricity with respect to the pump rotor body to provide a pump capacity; \n wherein the motor rotor and the pump rotor are incorporated into a common rotor which is a one piece item including a motor and a pump rotor portion and wherein the common rotor is fully supported by the pump stator; wherein the pump stator is fixed to the pump housing as a cantilever.
