ABSTRACT:
A fuel injection pump includes a casing; a drive shaft rotatably mounted in the casing and extending from a drive receiving end which is located outside of the casing to a point inside the casing; and first and second spaced apart seals each for preventing the flow of fluid between the casing and the drive shaft at the location of the seal. A chamber is formed between the drive shaft and the casing, the chamber being bounded at opposite ends thereof by the seals, and a vent passage extends from the chamber to a point on the surface of the casing to vent the chamber. The vent passage includes a portion defined by the clearance space between a screw threaded opening and a screw threadedly engaged with the opening. The screw is preferably a screw which secures the casing to the engine supplied by the pump. The vent prevents fuel escaping, in the event of seal failure, from the interior of an injection pump to the interior of an engine with which the injection pump is associated but does not require any additional components.
