Abstract

842,308. Diaphragm pumps. GUINARD, P. A. Nov. 14, 1958 [Nov. 18, 1957], No. 36758/58. Class 102(1). Diaphragms 9, 10 are secured to the heads of a piston 3 reciprocated in a cylinder 2 filled with oil, by a cam 18 passing through the piston and surrounded by a strap 19 pivoted to the piston at 20. A double cylinder head 5, 6 on one end forms together with a further diaphragm 7 an air chamber 8 and an outlet chamber 32. The pump chambers are provided with valves comprising seats 27 to which cages 29 supporting the valve springs 28 are secured. The Specification states that the piston heads may be provided with valve controlled ports in the zones 31 which are filled with oil which supports the flexed diaphragm.
