Abstract

1354037 Gas diaphragm pumps E BECKER 26 May 1972 [1 June 1971 15 March 1972] 25047/72 Heading F1N A diaphragm pump 1 operable to produce vacuum or pressure has its inlet 30 and outlet 31 connected to a two-position control valve 50, the valve 50 causing either the evacuated gas or the gas for compression to pass through a crankcase 5 and a silencer S. As shown the valve is positioned so that the pump produces vacuum at a port 52. Thus evacuated gas is pumped through the pumping chamber 8 by the oscillations of a diaphragm 3 by a crank driven connecting rod 2 disposedinthecrank-case 5, conventional inlet and outlet valves 13, 14 controlling the filling and emptying of the chamber 8. The evacuated gas leaves the pumping chamber 8 through a line 63 and is discharged to atmosphere through a line 64, the crank-case 5 and the silencer S. Movement of the valve 50 to its other position causes gas to flow intothe crank-case 5 through the silencer S and thence by lines 64, 60 to the pumping chamber 8. Gas at increased pressure is delivered through the line 63 and the valve 50 to an outlet port 57. The inside of the crank-case 5 is covered with sound absorbing material J.
