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 29):
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 stationary positioned inside the pump chamber, which pump stator has an elongated stator body, which is beam shaped 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.
