Abstract

1,239,162. Diaphragm pump. INTERNATIONAL STANDARD ELECTRIC CORP. July 10, 1969 [July 17, 1968], No.34742/69. Headings F1A and F1N. A diaphragm pump for liquids or gases comprises a housing 11, 12, 13 divided into an inner chamber 21 and outer chambers 20, 22 by flexible diaphragms 14, 15, the outer chambers having inlet valves 23, 25 and outlet valves 24, 26. The inner chamber 21 is evacuated to maintain the diaphragms in contact with backing plates 16, 17, which are reciprocated in unison by an eccentric 18. The inlet valves 23, 25 are opened at the end of the exhaust stroke of the associated diaphragm 14, 15 by a magnet 36, 37 acting on a magnet or ferromagnetic portion 34, 35 in the inlet valve, overcoming the force of a leaf-spring 27, 28. The eccentric 18, which is driven by an electric motor via a belt and a pulley 9, also operates a reciprocating piston vacuum pump Figs.2 and 3 (not shown) to maintain the reduced pressure in the inner chamber 21. Alternatively, the inner chamber may be evacuated and sealed.
