Abstract

1460586 Fuel injection pumps CAV Ltd 21 March 1974 [26 April 1973] 19820/73 Heading F1A In liquid fuel injection pumping apparatus wherein an injection pump 12 delivers fuel past a delivery valve element 17 to a distribution passage 14 in a rotary distributer member 11, movement of the valve element to an open position is accomplished against the action of a fluid spring. The fluid spring comprises a plunger 19 urged to bear against the valve element 17 by fuel trapped in a chamber 21. Fuel is charged to the chamber 21 through a non-return valve 23 from the passage 14. A stop 22 limits the extent of movement of the plunger. Closure of the valve element 17 is caused initially by the fluid spring but when flats on the element are covered fuel in the passage 14 acts to cause complete re-seating.
