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 method for producing a pendulum of a pendulum slide cell pump may include providing a prefabricated pendulum body and performing a post-machining operation on the pendulum body only at a plurality of contact locations at which the pendulum body contacts at least one of an inner rotor and an outer rotor of the pendulum slide cell pump.

Method for producing a pendulum of a pendulum slide cell pump

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.

Vane pump

A flow-controllable cell pump having a bearing element that may be positioned in a receiving shell of a pump housing such that the receiving shell may assume an operational connection with at least one of a bearing element, a pump chamber positioned between an inner rotor and a control slide valve. An outer rotor may be configured in the control slide valve, and suction kidneys may be arranged on both sides of the pump chambers in the pump housing. At least one pressure kidney may be offset on both sides of the pump chambers in the pump housing. The pressure kidney may be connected with a pressure connection socket, with a control slide valve arm configured on the control slide valve.
