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 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: 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: An anti-locking hydraulic brake system is described which includes a pump, the output of which flows through a pressure valve (20), a damping chamber (24), a check valve (28) and a throttle (3I) and is delivered to a pressure connection in communication with the wheel brake conduit. To ensure, in a compact structural design, a noise-minimizing hydraulic pressure source, while avoiding a flow back of pressure fluid from the brake system into the damping device, a check valve (28) is integrated into the damping device. A pressure valve is integrated with the check valve and damping chamber, with an elastomeric elastic member disposed in the damping chamber to absorb pressure pulsations.

摘要: An anti-lock hydraulic brake system which includes a brake pressure generator composed of a master cylinder, a brake power booster inserted upstream thereof and a pressure modulator interposed between the master cylinder and the brake power booster. A resetting unit is formed by supplementing the pressure modulator with a valve assembly which connects a resetting chamber of the pressure modulator to either a pressure-compensating reservoir or an auxiliary-pressure source. The braking pressure in the wheel brakes is controlled, according to a time-multiplex method, by wheel valves inserted into the pressure-fluid conduits and by the pressure modulator. In order to check the operability of the brake and of the anti-lock control system, a pressure switch is connected to the pressure modulator and a test circuit is provided which, at predetermined points of time, initiates a test cycle, actuates the valves and compares the valves' operation with the reaction of the pressure switch.
