ABSTRACT:
A slide valve is described that has the capability to open rapidly at a rnably controlled speed. The valve has two concentric tubes with each tube having a plurality of slots. In the valve closed position the slots are misaligned both axially and circumferentially. In the valve open position the slots in the inner cylinder coincide with respective outer slot openings. On moving from the closed to open position the inner tube is connected to a bracket that rides in an outer tube cammed slot. The bracket and inner tube to which it is connected are driven first longitudinally in the axial direction and then rotated on its axis while being driven further in the axial direction.
