Method of and apparatus for actuating the torque transmitting system and

A valve assembly for controlling fluid flow to an actuator, including first and second throttles for controlling partial flows therethrough, which together form a full flow to the actuator and which function indepedently from each other and are formed each by a variable metering orifice, and a flow control valve for controlling fluid flow through the first throttle and including a valve spool and a spring for biasing the valve spool to a position of a maximum predetermined fluid flow through the first throttle.

Valve assembly

A pressure-limiting valve including a housing, a valve seat located in the housing bore, a sealing element displaceable in the bore between a closed position in which it engages the valve seat, and an open position in which it is spaced from said valve seat, and a spring for biasing the sealing element to the closed position thereof, with the valve seat being pressed into the housing bore, with a valve seat position being adjustable during the pressing-in process, and with continuous control of pressure-in forces.

Pressure-limiting valve and method of setting opening pressure of the

A valve assembly for controlling volume flow from a discharge device to an actuator and including a discharge throttle, and a flow control valve for controlling flow through the throttle and having a piston, and end portion of which overlaps a channel for returning excess fluid to a suction side of the discharge device and has an end region forming a seated valve preventing leakage past the end region, when the end region completely overlaps the return channel.
