Abstract

The sleeve valve has several outlet perforations on the sleeve outside wall. The sleeve bottom has a contact seat and its upper end has a pressure reducer chamber. The valve has an inner cylinder open at the top and bottom and it slides within the outer sleeve. The movement of the inner sleeve controls the number of the perforations open to flow. The sliding sleeve lower end has a stop collar (40) contacting outside the sleeve bottom. The contact stop has a sharp edge for the line contact between the sleeve and the stop. A flexible sealing ring (42) is placed between the bottom valve seat (46) and the bottom closing rings (30).
