Abstract

1297033 Fuel injection pumps; I C engine fuel injectors CATERPILLAR TRACTOR CO 25 Feb 1970 9164/70 Headings F1A and F1B In a fuel injection pump 11 in combination with an inwardly opening injection nozzle 12 having an accumulator chamber 28, the pump delivery valve includes a valve member 42 and sealing surface 44 which define, when in the closed position, a limited passage 52 which allows reverse flow from the nozzle. The passage may be formed by a radially extending groove in the face surface of the delivery valve member, Fig.2 (not shown). The injector nozzle is of the type described in Specification 1243034.
