Abstract

513,349. Fuel injection pumps. BRYCE, Ltd., and GREEN, G. W. A. July 25, 1938, No. 22016. [Class 102(i)] A delivery valve for a fuel injection pump, adapted to prevent drip at the nozzle, comprises a member 7 having a conical extension 11 cooperating with a seating 9 in the housing 1, and an annular projection 15 engaging the cylindrical walls of the housing 1. The member 7 is of cylindrical form provided with flats 14 and loaded by a spring 19 and its lift is limited by a stop 28 loaded by a spring 26. Throttle bores 18 are provided in the member 7 and allow passage of fuel until the projection 15 is lifted clear of the housing 1 when the larger passages are opened. Specification 455,778 is referred to.
