ABSTRACT:
A rotary control valve for an expansion fluid driven engine has a body with inlet and outlet ports and a distribution port communicating with an engine cylinder. A shaft in the body has first and second discs thereon and rotates in synchronization with reciprocation of the engine piston. The first disc has a pressure fluid passage therethrough and the second disc has an exhaust fluid passage therethrough. Sealing pistons in the body urge against the discs and have passages therethrough respectively connecting the pressure fluid passage with the inlet and distribution ports and the exhaust fluid passage with the distribution and outlet ports. The rotation of the discs alternately permits and stops flow of fluid to and from the cylinder.
