Abstract

1324935 Fuel injection pumps SOC INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE 2 Dec 1971 [4 Dec 1970] 55897/71 Heading F1A A fuel injection pump piston 3 delivers fuel from a cylinder 1 through an axial passage 15 in a valve 7 and then past a delivery valve 4 to an injection passage 6, the valve 7 being provided to allow the relief of pressure waves in the passage 6 back to the cylinder 1. If a pressure wave occurs in the passage 6 with the delivery valve 4 closed, fuel in an annular by-pass passage 30 connected to the passage 6 flows through radial channels 31 into a chamber 20 where it acts on a shoulder 7d to move the valve away from its seat 18. The valve 7 is urged towards its closed position by a spring 8 bearing against a cup member 16 held in position by an expanding ring 24. During pump delivery the pressure in the cylinder 1 assists the spring 8 in keeping the valve 7 seated.
