ABSTRACT:
A fuel pumping apparatus includes a housing in which is located a plurality of reciprocable tappet assemblies including tappet bodies. The tappets carry rollers for engagement with cams respectively. In order to prevent rotation of the tappet bodies adjacent pairs of the tappet bodies are provided with mutually facing and mutually inclined flats which are engaged by wedge-shaped guide members. The flats and guide members permit reciprocable movement of the tappet bodies but prevent rotation thereof.
