Abstract

1476898 Diaphragm pumps GENERAL MOTORS FRANCE 30 April 1976 [5 May 1975] 18657/75 Heading F1A A diaphragm fuel pump comprises a diaphragm 5 clamped between a housing portion 3 and a valve support plate 14 by a crimped metal band 6, the plate 14 having seats 15, 16 surrounding the valves and receiving inlet and outlet housings 17, 18 provided with coaxial or radial connections 19, 20. Plate 14 and housings 17, 18 may be of plastics, and may be connected by ultrasonic welding after assembly in the required angular orientation, a filter 35 being located between the inlet housing and its seat. The inlet and outlet valves may comprise press-fitted, flexible members 22, 32, as shown, or spring-loaded annular discs, Fig. 2 (not shown) located on projections from the plate 14.
