Abstract: A fuel injection pump has a barrel with a central bore communicating through axially staggered fuel inlet and outlet ports with an outer peripheral recess in the barrel which, in cooperation with a fuel pump housing, forms an annular fuel receiving cavity about the pump barrel. A relatively large fuel reservoir in the housing communicates with the annular cavity through fuel inlet and outlet conduits in the housing, the outlet conduit being aligned with the outlet port in the pump barrel. A plunger having a scroll surface at one end is rotatably and reciprocably received in the pump barrel bore, and the scroll surface is selectively registrable with the fuel ports. A pulse shield of hardened material is disposed within the fuel reservoir in alignment with the fuel outlet conduit to deflect fuel from the outlet conduit into the main portion of the reservoir and to prevent erosion of the housing surfaces.

Abstract: Conventional lifter assemblies are relatively expensive to manufacture and generally extend laterally significantly beyond the ends of the roller surface thereof. As a result, fuel pumps utilizing such conventional assemblies must be spaced relatively far apart so that a sufficient roller surface is provided to contact a camshaft. Further, such assemblies are generally relatively heavy, leading to high inertial changes on reciprocation thereof. The ends (42,43 or 142,143) of the roller (14 or 114) are adjacent the inner diameter of the sleeve (28 or 128), whereby the roller (14 or 114) of the resulting lifter assembly (10) extends nearly the full width thereof. A roller holder (30 or 130) fits within one end (32 or 132) of the sleeve (28 or 128) and holds the roller (14 or 114) in a cavity (36 or 136) therein.
