Abstract

A housing (1) has a hollow piston (6) with a shoulder (8) approximately half way along it acting as a locating face for a spring (7) which is located at the other end by a collar (9) on a sleeve (10) around the top of the piston. The outlet port (18) at the bottom of the piston is preceded by a chamber (18) housing a spring loaded ball (4) seating in a conical depression one side of a block under the pointed end of the piston, closing a hole (13) through the block. A hole (20) of smaller diameter than the bore (5) of the piston (6) is in line with this hole (13), and the bore of the piston acts as a chamber to provide a supplementary closing force during the return stroke of the piston.
