Abstract

1,065,225. Reciprocating pumps. GENERAL MOTORS (FRANCE). Feb.3, 1966 [March 25, 1965], No. 12644/65. Heading F1A. In a diaphragm fuel pump the diaphragm 3 is pressed into sealing contact with the flange 2 of the housing 1, which may be of metal of plastics material, by a valve and seat plate 4 shaped from sheet material the periphery of which is pressed into engagement with the diaphragm by a sheet metal cover 5 crimped over the flange 2. The inlet valve seat 23 is enclosed to form an inlet chamber either by a rigid annular member Fig.7 (not shown) or as shown by a resilient member 31 having a rigid insert 32 which between them form air pockets to provide a pulse damper in the surrounding outlet chamber. The inlet chamber communicates through a port 34 and filter 35 with the inlet 41. The diaphragm is clamped between member 7, which may be of plastics material, and member 8. The member 7 has a depending slotted sleeve having a lot motion connection with cam actuated push rod 14. In a modification the slotted sleeve is formed on the lower member and in a further modification the sleeve is a separately formed member attached to the diaphragm. A sealing washer may be clamped between the cover 5 and the valve plate 4 Fig. 8 (not shown) or the valve plate may be formed to seal with the diaphragm and cover Fig.9 (not shown).
