ABSTRACT:
A valve arrangement includes a valve member, which rotates continuously in one sense. The generally cylindrical head of the valve member, within the housing, is formed to co-operate with various ports to create reciprocation in the actuator. It is preferred to provide some vibration of the valve member, to assist in overcoming the effects of friction.
