摘要： A simplified and improved hydraulic brake system has at least one valve arrangement for the brake pressure modulation in a wheel brake. Furthermore, a high-pressure pump is provided to return pressure medium from the wheel brake into a main brake cylinder in the case of an anti-lock control operation or to deliver pressure medium from the main brake cylinder into a wheel brake during drive-slip control operation. A shut-off valve with a spring-actuated through-flow position and a shut-off position, which can be selected by the pressure at the main brake cylinder end, is arranged upstream on the suction side of the high-pressure pump. The hydraulic brake system with anti-lock and drive-slip control device is used in motor vehicles.

摘要： A brake unit having a brake line extending between a master brake cylinder and a wheel brake. A changeover valve is included in the brake line on the master brake side and a valve arrangement for the brake pressure modulation is on the wheel brake side. A return line extends from the valve arrangement to a high-pressure pump for feeding a pressure medium into the brake line. Connected to the return line is a storage chamber for the pressure medium taken from the wheel brake. A suction line starts from the brake line on the master brake cylinder side, with a hydraulically switchable check valve connected to the return line. A non-return valve is arranged between the connection of the suction line and the storage chamber. The high-pressure pump can draw pressure media from the master brake cylinder. The entry of the pressure media into the storage chamber from the suction line is prevented by the non-return valve. The hydraulic brake unit is suitable for motor vehicles.

摘要： A hydraulic control arrangement for at least two hydraulic consumers, comprises two pressure compensated multiple position valves, respectively coordinated with the two consumers, and each including a pressure compensating control member which controls a control conduit coordinated with a reversing or unloading valve, which, depending on its position and those of the multiple position valves control flow of pressure fluid from a pump over the multiple position valves to the respective consumer or to a return conduit. This will assure that even during parallel operation of both consumers, the output of the pump will be adjusted to the consumer load in such a manner that energy losses are substantially avoided and control of the two consumers independent from each other is assured.

摘要： An apparatus for damping courses of motion in particular for damping resilient wheel suspension systems in vehicles, having a damping piston that is displaceable inside a jacket tube which separates two work chambers and is connected to a piston rod. Between the work chambers there are flow connections, through which a flow is possible in only one direction, because of a unilateral actuation direction of separate check valves. The flow connections have throttle cross sections the size of which is definable by the position of a control slide inside a guide bore. The control slide is actuated via a control rod leading outside the jacket tube and is movable with two degrees of freedom. A motion in the direction of the first degree of freedom varies the throttle cross sections in the same direction, while a motion of the control slide in the direction of the second degree of freedom varies the throttle cross sections in opposite directions. The proposed apparatus is thus suitable for both passive and active damping control.

摘要： A plunger system in a brake line between a master brake cylinder and a wheel brake cylinder of a vehicle, for modulating a brake pressure in the event of a sensor-detected danger of wheel locking or wheel spinning. The plunger system has a plunger that is axially displaceable in a housing. At one end, the plunger engages a variable pressure chamber toward the master brake cylinder and at the other it engages a variable pressure chamber toward the wheel brake cylinder. It has an axial bore, through which a rod passes, between the two pressure chambers, and this bore can be closed on opposite ends if there is a danger of wheel locking or if wheel spinning occurs. The closure of the axial bore is effected by an axial motion of the plunger, which takes place if the wheels lock, on the one hand, and if they spin, on the other.

摘要： A brake system having a master brake cylinder with at least one piston in a stepped bore in which the piston is acted upon at one end by a piston rod and on the other end defines a pressure chamber, from which an outlet or a brake line leads to wheel brake cylinders of at least one brake circuit. The pressure chamber, or the brake line discharging from this pressure chamber communicates on the one hand with a compensation chamber and on the other with an annular chamber, the volumes of both these chambers being variable contrarily by movement of the piston. The connection between the pressure chamber and the compensation chamber is interrupted by a valve, and a connection is then established with a fluid reservoir. A suitable amount of fluid can then be transported from this fluid reservoir into the compensation chamber by means of a return pump.

摘要： A hydraulic dual-circuit brake system with an anti-skid system and traction control in motor vehicles which has a four-channel hydraulic unit with electromagnetic control valves and a return pump having two separate pump elements. For supplying brake pressure during traction control, an additional hydraulic unit is provided, which has a charging valve for connecting the brake fluid tank to a pump element, which pump element is assigned to a brake circuit containing at least one driven wheel, and a reversing valve for alternatingly connecting this pump element to the master brake cylinder or the brake fluid tank. To provide economical brake pressure supply during traction control, the aforementioned pump element is embodied as a self-aspirating high-pressure pump, and a check valve having a flow direction toward the pump element is incorporated into the connection between the control valves disposed in the brake circuit assigned to this pump element and the inlet of the pump element.

摘要： The control device for a hydraulically operated load includes a multiway piston valve defining a plurality of working chambers, a plurality of control chambers, a piston having axial and radial bores acting as first choke channels and a control collar cooperating with the control chambers to act as additional choke channels, a piston manometer valve biased by a spring and connected between a pump channel and a return flow channel. A control conduit including at least one choke is connectable via additional choke channels between the pump channel and the return flow channel and has a branch conduit leading to the spring-biased end of the manometer piston. The valve piston is displaceable from its neutral position into an intermediate control position in which in the range of the fine adjustment of the flow the pressure from the load is applied through the control conduit to the manometer piston to provide a load compensated control. In the end control position of the multiway piston the load compensated control is disconnected and maximum through-flow is attained.
