摘要： The invention discloses a high pressure diesel fuel pump comprising a pumping assembly and a drivetrain assembly (100). The pumping assembly comprises a pump housing and a plunger mounted along a pumping axis (A- A'). The drivetrain assembly (100) comprises 5 a drive shaft (110) and a cam mounted within a cambox (115) of a drivetrain housing (105). The plunger is arranged for reciprocating linear movement along the pumping axis (A- A') within a pumping chamber of the drivetrain housing (105) upon rotation of the cam. The drivetrain assembly (100) further comprises a shoe guide (130) mounted between the cam and the plunger within a guide chamber (120) and being adapted to receive a cam follower for contact with a driven end of the plunger. The shoe guide (130) is adapted to provide at least one flow passage (125) between the shoe guide (130) and an internal wall of the guide chamber (120).

摘要： The invention relates to a high pressure diesel fuel pump comprising a drivetrain assembly within a drivetrain housing and a pumping assembly. The drivetrain assembly comprises a cam mounted in a cambox, a tappet member arranged for reciprocal movement with the cam within a tappet chamber, and a spring mounted in a spring chamber acting on an upper surface of the tappet member. The pumping assembly comprises a pump housing and a plunger mounted within a bore formed in the pump housing for reciprocal movement along a pumping axis under the influence of the tappet member. The housing comprises a vent arranged to connect said spring chamber and/or said tappet chamber with the cambox and a low pressure inlet for delivery of fluid to the drivetrain assembly, characterised in that the low pressure inlet is arranged to feed into the spring chamber. The invention also covers a drivetrain housing.
