Abstract
Abstract A rotary valve having an inner cylindrical sleeve, an outer cylindrical sleeve in sealing contact with the inner sleeve, the inner sleeve being closed by a wall closure at one end, and openings in the sleeve surfaces to allow liquids to enter the chamber inside the inner sleeve and exit through the open end of the inner sleeve. The valve is provided with elements to prevent longitudinal movement of the sleeves, an element to rotate the openings into and out of coincidence, and a snap-ring-flange combination to facilitate engagement with a containing surface.
