A hydraulic conveying device for an internal combustion engine may include a pendulum slide pump including an inner rotor drivingly connected to an outer rotor via a plurality of pendulum slides. A hydraulic actuation device may change an eccentricity between the inner rotor and the outer rotor via an actuation member. The actuation member may be prestressed by a spring device. The actuation device may further include a first pressure-setting chamber and a second pressure-setting chamber for adjusting the actuation member. At least one of the first pressure-setting chamber and the second pressure-setting chamber may be connected via a control valve to a pressure side of the pendulum slide pump. A hydraulic line may connect the pendulum slide cell pump downstream to a hydraulic medium filter. The control valve may be connected to the hydraulic line upstream of the hydraulic medium filter.

Hydraulic conveying device and hydraulic system

A vane pump is disclosed. The vane pump includes at least an inner rotor and at least one vane. The inner rotor is rotatably mounted in a cage and the at least one vane is configured in at least one substantially radial slot, the slot is configured in the inner rotor, wherein the slots and the vanes are arranged asymmetrically on the inner rotor.
