Abstract
A rotary control valve has a control surface carrying flow control channels. A
control plate fits against the control surface to form closed passageways between the control plate and the channels in the control surface. The control plate includes a first opening located to communicate with a first one of the flow control channels and a second opening located to communicate with another of the flow control channels. The valve has application to controlling the flow of fluid from a reciprocating piston pump. The valve may be integrated with a reciprocating piston pump.
