Abstract

1,192,467. Reciprocating gas pumps driven by vacuum engines. HADLEY MFG. CO. Sept. 4, 1967 [Oct. 5, 1966], No.40243/67. Headings F1N and F1S. A reciprocating gas pump comprises a compression piston 71 moving in a cylinder 51 and driven by a vacuum operated reciprocating motor having a diaphragm 17 dividing a housing 11, 12 into two chambers 18, 19 and connected to the compression piston 71 by a rod 28 passing through a bore 27 in the housing 12, the bore being provided with an O-ring seal 83 which prevents vacuum being lost from chamber 19. The motor chambers 18, 19 are alternately connected to vacuum and atmospheric pressure by a valve consisting of a member 102 oscillated on a shaft 101 by the reciprocating movement of a dummy piston 36 in a dummy cylinder 24 and connected to the diaphragm 17. An arcuate slot 103 in the member 102 connects vacuum at a port 104 alternately to ports 94, 95 leading by lines 96, 97 to respective vacuum chambers 18, 19. Gas to be compressed enters the cylinder 51, during the return stroke of the piston 71, through a filter 47, apertures 78 in a ring 44 and past an O-ring seal 76 encircling the piston 71. During the compression stroke the seal 76 prevents escape of gas from the cylinder 51, and compressed gas is discharged through an outlet valve 62.
