Abstract: A bearing assembly (10; 100) suitable for use as a journal bearing for a high-pressure fuel pump is disclosed. The bearing assembly comprises a generally tubular bearing bush (20; 200) made entirely from a PEEK-based material, and defining an inner bearing surface (22; 222), and a housing (40; 400) comprising a generally cylindrical bore (42; 442) for receiving the bush (20; 200). The bush (20; 200) and the housing (40; 400) are arranged concentrically around a bearing axis (A). The housing (40; 400) includes cooling means (54, 56, 58; 454) for cooling the bearing assembly (10; 100), in use.

Abstract: A high-pressure fuel pump assembly (200) for use in an internal combustion engine is disclosed. The fuel pump assembly (200) comprises a pumping plunger (201; 301) for pressurising fuel within a pump chamber (220) during a plunger pumping stroke, a rider member (206) co-operable with a drive, and an interface member (226; 326) for imparting drive from the rider member (206) to the pumping plunger (201; 301) to perform the plunger pumping stroke, the interface member having an interface side (236; 336). The interface member (226; 326) comprises fluid flow means (250, 252, 254; 350, 352, 354, 368, 370, 372) for providing a fluid flow path from the pump chamber (220) to the interface side (236; 336) of the interface member (226; 326) such that, in use, a hydrostatic lubricating fuel film is generated between the interface member (226) and the rider member (206) on pressurisation of fuel in the pump chamber (220).

Abstract: A high-pressure fuel pump assembly (200) for use in an internal combustion engine is disclosed. The fuel pump assembly (200) comprises a pumping plunger (201) for pressurising fuel within a pump chamber (220) during a plunger pumping stroke, and being slidably received in a plunger bore (216); a rider member (206) co-operable with a drive; and an interface member (250) for imparting drive from the rider member (206) to the pumping plunger (201) to perform the plunger pumping stroke, the interface member having an interface side (256) co-operable with the rider member (206). The pumping plunger (201) comprises fluid delivery means (228, 230, 232, 234, 236) for delivering fuel from the pump chamber (220) to one or more contact surfaces (227, 238) of the pumping plunger (201), thereby to lubricate the contact surfaces (227, 238).
