Abstract: A scheduled fluid control valve which performs a pre-established sequence of flow rates and timing schedules in response to pressure pulses in the controlled fluid. The valve consists of a generally cylindrical housing connected to a source of pressurized fluid and containing circular plates of cylindrical control surfaces coupled to actuating means responsive to the presence of pressurized fluid. The actuating means includes an actuator plate or cylinder, a biasing spring, and a longitudinal shaft or cylinder upon which is incised at least one generally helical groove within which track one or more follower pins. Pressurized fluid causes the actuator plate or cylinder to rotate, following the path defined by the helical groove, resulting in relative movement of the control surfaces whereby the schedule embodied in the relative size and placement of fluid ports through the control surfaces is performed.
