Control valve for clutch actuating device of motor vehicle, has valve body moved to one switching position by valve rod that is centered in initial position, where spring and magnetic forces indirectly act on rod that is pre-stressed

摘要

The valve (7) has a pressurizing medium supply connection and pressurizing medium removal connection, where the valve takes two switching positions depending on guiding and actual signals of a clutch actuating device. A valve body (43) is moved to a switching position by a valve rod (19) that is centered in an initial position, where spring force and magnetic force indirectly act on the rod. The spring force is represented as the guiding signal and the magnetic force is reversely represented as the actual signal. The rod is pre-stressed by spring arrangements (21, 23) in the initial position.
