Abstract

7369. Ellis, J. N. May 17. Check lift valves.-In a check valve of the kind operated in conjunction with a balance piston for preventing the action of the back-pressure on the valve, the piston 13 is formed with an extension 14 terminating in a flange 15 engaging inturned lugs 16 on the valve 10, or in a conical point bearing upon the valve. The valve is loaded by an adjustable spring 17 or a lever-weight in the known manner.
