Abstract

611,057. Valve accessories. PRECISION DEVELOPMENTS CO., Ltd., and OLAH, G. Oct. 10, 1945, No. 26466. [Class 135] [Also in Group XXVIII] The end of the cylinder of a reciprocating pump is provided with a large diameter annular inlet valve 6 that is guided on a thin tubular member 11 and loaded by a spring 8. A delivery valve 13 is guided within the tubular member 11 which is enlarged to form a seat 12 for the valve. During the delivery stroke of the pump, the tubular member enlarges due to internal pressure and improves the seal with the inlet valve.
