Abstract

270,087. Turner, W. May 1, 1926. Check lift valves.-The piston cup leather e, fitting the cylinder of an air pump, constitutes a seat for a spring-urged inlet valve b. On the upward stroke of the piston, the valve opens and air passes round the stem and between the bevelled edges of the valve and leather. An outlet valve is provided in the pump base, having an upper surface of rubber and a cup leather attachment k, pressed upward by a spring.
