Abstract (en)
A fluid pump (10) for use in delivering fuel to a common rail of an internal combustion engine comprises a drive shaft housing (26), a drive shaft (14) for driving at least one pumping plunger (16) and a bearing (30) for supporting the drive shaft (14) within the drive shaft housing (26). The pump provides a means (56, 48) for supplying fluid to the bearing (30) and means (40) for maintaining a fluid pressure difference across the bearing (30) which, in so doing, increases the effect of convection cooling on the bearing (30), in use.
