Abstract
A drive device for driving an oil pump (12) using a drive element (3), the oil pump (12) and the drive element (3) comprising axes (13, 8) that are arranged parallel to and offset from each other. It is suggested that the drive element (3) comprises an internal gear (11) with internal gearing and the pump (12) comprises a driving wheel (14) with outer gearing, and that the pump (12) can be driven by engaging the gears of the internal gear (11) and the driving gear (14).

A drive device for driving an oil pump (12, 26) using a drive element, the oil pump and the drive element have axes that are arranged parallel to and offset from each other, the drive element having an internal gear (11, 25) with internal gearing, and the oil pump (12, 26) having a driving wheel (14, 28) with outer gearing, the oil pump (12, 26) can be driven by engaging the gears of the internal gear (11, 25) and the driving gear (14, 28).
A drive device for driving a flow of pressurized oil, the drive device comprising:
- an oil pump (12, 26) having driving wheel (14, 28) with outer gearing which rotates about a pumping axis;
- and
- a drive element drive element (3, 20) having an internal gear (11, 25) with internal gearing, the internal gear rotates about a driving axis, the driving axis being parallel to and offset from the pumping axis, the oil pump (12, 26) being driven by engaging the outer gearing of the oil pump (12, 26) with the internal gear (11, 25) of the drive element drive element (3, 20).
