  • Internal combustion engine
    Patent number: 7100744
    Abstract: An engine is described having a hole for a dipstick which is closed by a cap from which the dipstick depends. The engine body is formed with an overhanging lip adjacent the mouth of the hole, and the cap comprises a spigot rotatably received in the mouth of the hole and a flange extending radially outwards from the spigot to cover the mouth of the hole. The flange is non-circular so that by rotation of the cap relative to the hole, a radially projecting portion of the edge of the flange may be selectively engaged beneath the overhanging lip to prevent axial displacement of the cap and the dipstick relative to the engine body.

  • Balancer shaft assembly
    Patent number: 6752117
    Abstract: A balancer shaft assembly for an engine comprises a housing mountable on the engine block, and rotatably supporting at least one balancer shaft (16,18; 16′,18′) connectable for rotation with the engine crankshaft. The housing is formed in two parts (12,14; 12′,14′) and defines pillar blocks (30) for journalling the or each balancer shaft (16,18; 16′,18′). A groove (28; 28′) is formed in the split plane of at least one of the two mating parts (12; 12′) of the housing, which groove (28; 28′) when the parts (12,14; 12′,14′) are mated to one another defines an oil gallery by way of which lubricant is supplied to the pillar blocks (30) supporting the or each balancer shaft (16,18; 16′,18′).
