ABSTRACT:
The present control valve is intended to handle highly viscous material such as concrete mixes. For this purpose two valve plates are arranged in a valve housing in such a manner that in one position of the two valve plates relative to each other, one valve plate closes a suction inlet port and opens a pressure outlet port while the other valve plate opens a suction inlet port and closes a pressure outlet port. When the positions of the valve plates change, their respective operation is reversed. The valve plates are supported by drive rods which in turn are supported at both ends of the valve housing in respective slide bearings. One end of each drive rod is operatively connected to a hydraulic drive. The opposite end of each drive rod carries a piston movable in a cylinder, the far end of which is operatively connected to a rinsing liquid container. The rinsing liquid conduits extend through grooves in the slide bearings of each drive rod, whereby these rods are cleaned to protect the rod bearings.
