Abstract

A discharge valve, especially for liquids, has a tubular body with an inlet and a circumferential outlet. A sleeve is slidable on the body around the outlet and has a large number of holes affording varying flow through the outlet, depending upon the sleeve location. In an extreme or shut-off position of the sleeve, a bearing ring on the body is abutted by a packing ring on the sleeve carrying an O-ring to seal against the bearing ring.
