Abstract
Fuel injection pump comprising a shaft adapted to be operated in synchronized relationship with the engine to which the pump is associated, a fluid pressure-operable device located in said shaft and through which a rotary movement is communicated to it, whose device comprises an elongated support member adapted to secure to the shaft, the support member of which has a first portion provided with a non-circular outer peripheral surface and a second portion with a circular outer peripheral surface, an input member arranged for angular movement about the said second portion of the support member, the inlet member of which is connected, in use, to a motor drive shaft, the inlet member defining a cylinder coaxial with the support member, a piston located in the cylinder, means elastics that drive the piston to one end of the cylinder as opposed to fluid pressure, the piston of which has e a portion of complementary shape with respect to the first mentioned portion of the support member and is slidable on this first portion but without rotatingly coupling thereto, the piston having a helical groove or equivalent connection with the inlet member, and valve means that they operate by controlling the application of fluid pressure to said piston, the arrangement being such that, by varying the fluid pressure applied to said piston, the angular fit between the inlet member and said support member will also vary.
