    摘要: A variable displacement pump includes: a first pressure control chamber; a second pressure control chamber; a spring arranged to urge the cam ring in a second swing direction; a hydraulic pressure supply valve arranged to be opened by a predetermined hydraulic pressure, and thereby to introduce a control hydraulic pressure to the first control chamber; a connection passage formed in the housing or the cam ring, and arranged to connect the first pressure control chamber and the second pressure control chamber; and a relief circuit arranged to connect the second pressure control chamber and a low pressure side, to be opened or closed in accordance with a swing position of the cam ring, and to be closed when the cam ring is swung by a predetermined amount in the first direction.

    摘要: A hydraulic feed device may include a pendulum-slide cell pump having an internal rotor drivingly connected to an external rotor via pendulum slides. A hydraulic positioning device may have a positioning element for changing an eccentricity between the internal rotor and the external rotor. The positioning element may be preloaded by a spring device for setting a maximum eccentricity. The positioning device may have a first pressure adjusting and a second pressure adjusting chamber for adjusting the positioning element. The first pressure adjusting chamber may be permanently hydraulically connected to a pressure side of the pendulum-slide cell pump and configured to hydraulically counteract the spring device. The second pressure adjusting chamber may be controlled via a control valve and hydraulically connected to the pressure side of the pendulum-slide cell pump and configured to hydraulically counteract the spring device.

    摘要: A lubricant pump system may include a lubricant pump controlled by a proportional valve. An actuating unit may be disposed in the lubricant pump and configured to control a delivery output of the lubricant pump. A first pressure chamber and at least one second pressure chamber may be configured to adjust the actuating unit against a spring, wherein the second pressure chamber is smaller than the first pressure chamber. In response to a failure of the proportional valve, the lubricant pump may be exclusively pressurized via the at least one second pressure chamber.

    摘要: A pump has a pressure chamber and a control ring which is mounted to pivot about a pivoting axis and which undergoes a pivoting motion. The control ring can be pivoted about a deflection angle during its pivoting movement. An aperture is provided in the pressure chamber of the pump. The aperture opens or closes to varying degree based on the pivoting motion of the control ring. In a hydrodynamic retarder with such a pump, a lubricating and cooling medium is supplied at least to bearings of rotating components of the retarder. Differentiated lubrication and cooling, at least of the bearings, can be brought about during braking operation and during non-braking operation of the retarder.
