Abstract

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.
