IPC: F04B35/00
Filed: 1984-11-23
Abstract: A housing 15 forms a chamber 123 with a piston 127 which bears a valve member 193. As the piston moves under the influence of pressurized fluid it approaches port 302 and compresses spring 201. At contact, the port opens the valve 193 allowing fluid to pass through port 191, equalizing the pressures on either side of the piston and permitting spring 201 to open the valve fully and keep it open throughout the return stroke until studs 221 contact the casing to close the valve. During the upstroke the valve is held closed by pressure differential across it. <IMAGE>
