    摘要: A hydraulic pump which is furnished with a bushing-type closing element (11) for the purpose of damping pulsations of pressure and of the delivery flow. The closing element (11) turns the delivery flow several times and contains a damping chamber. An optimum adjustment of the damping device is possible by varying the external diameter of the end portion (12) of the closing element (11) and by varying the reach of screw of the closing element (11).

    摘要: The valve includes a control piston axially slidable in a cylindrical bore which controls the cross-sectional area of an orifice of a connection between the cylindrical bore communicating with a pressure port and a user port. The control piston is acted on by a spring and a pressure which is reduced relative to the pressure at the pressure port. A cushioning arrangement acting on the control piston avoids occurrence of pressure surges affecting the control piston behavior.

    摘要: A valve is disclosed for connecting a user port with a pressure port or a return port as required. A closure member which is acted upon by a pressure piston is shifted from a first into a second valve position. By disposing a throttle in the return port, a balanced pressure is achieved on all sides of the closure member during a valve position change process so that the valve changes from the first into the second position safely and rapidly.

    摘要: In a hydraulic motor vehicle brake system with slip control comprising a pressure accumulator (13), a hydraulic pump (23), a non-return valve (2) and a brake power booster (17). The pressure outlet of the pump (23) is connected with the pressure accumulator and with an inlet of the brake power booster (17) via the non-return valve (2). The outlet side of the non-return valve (2) is connected with the inlet of the brake power booster (17) via the pressure accumulator (13) in order to reduce noises caused by pressure pulsations in the fluid flow of the pump (23).

    摘要: The spherical piston pump comprises an outer stator and an inner rotor rotatable on a control pintle provided with supply and discharge channels. The rotor contains at least one radial bore in which is slidable a spherical piston including an outer ball, a cylindrical sleeve and an inner ball. The outer ball, sleeve and inner ball are not fastened to one another and can be replaced independently of each other. Annular sliding members made of low-friction and sound-damping material can be integrated into the ends of the sleeve, each of the sliding members being in line contact with the associated one of the two balls. The construction provides good volumetric efficiency even at high pressure and an improved overall efficiency of the pump.
