Abstract

A fuel delivery element having a piston (1) with an oblique control edge (3) co-operable with a spill port (not shown) in a cylinder (2), for injection pumps of diesel engines, in which pumps the pistons of all the delivery elements are rotatable through equal angles during regulation and some of the pistons have no effective delivery stroke, or a smaller effective delivery stroke than the remaining pistons, during the no-load and low load positions. The oblique control edge (3) of each said piston has a uniform slope and is provided in the effective range of no-load and low load positions with a recessed surface (60) of such small depth that a throttle gap of extremely small cross-sectional area is produced. <IMAGE>
