ABSTRACT:
Fuel pump for delivering high pressure fuel to a fuel injection system of an internal combustion engine is provided. The fuel pump has a body, a drive shaft rotatably mounted in the body, at least one cam on the drive shaft, a plurality of pumping plungers mounted in the body for movement in the radial direction relative to the axis of rotation of the drive shaft, a pumping chamber defined radially outwardly of each plunger, and a delivery valve associated with each pumping chamber. Each pumping plunger is mounted in a support member which provides sliding support for its associated plunger in the circumferential direction of the drive shaft over substantially the entire length of the plunger in all working positions thereof. Each plunger is coupled to at least one cam by a pin which is secured to the plunger and extends outwardly from the plunger through a slot which extends through the support member in the axial direction of the drive shaft. This arrangement obviates the need, which exists in conventional radial piston pumps, for the piston to extend outwardly of the member in which it is mounted to engage with the cam or the cam follower.
