ABSTRACT:
A control valve apparatus is described which is intended for selective transmission of pressure to at least two pressure spaces. A magnetic control device is provided for selectively applying a hydraulic system pressure to the respective pressure spaces. As another function, the apparatus may simultaneously depressurize the two pressure spaces through the application of a control pressure to the control valve apparatus. To minimize the required installation space and the manufacturing cost, the control valve apparatus is comprised of a single control valve, the control piston means of which can be exposed to the control pressure against the force of a restoring device and can be moved into intermediate control positions by means of the magnetic control device.
