摘要： A fuel pump (1) is provided for pressurising fuel in a high-pressure fuel injection system. The fuel pump (1) comprises a pump head (7), a pumping element (8), a frame (12) and a casing (3). The pump head (7) has a pumping chamber (7a) that is arranged to receive fuel to be pressurised. The pumping element (8) is arranged to reciprocate responsive to movement of a driving element (10), the pumping element (8) defining, in part, the pumping chamber (7a) so that, in use, as the pumping element (8) reciprocates, a force, transferred from the driving element (10), is applied to the fuel within the pumping chamber (7a) to pressurise the fuel. The frame (12) is arranged to support the driving element (10) and the pump head (7). The casing (3) defines an internal volume (5) for containing fluid, wherein at least a part of the frame (12), at least a part of the drive element (10), and at least a part of the pumping element are received in the casing.

摘要： A fuel pump assembly for use in an internal combustion engine comprises a pump housing (10), at least first and second pumping plungers (16a, 16b) for pressurising fuel within a respective one of first and second pumping chambers (20a, 20b); and first and second tappets (22a, 22b), each being associated with a respective one of the pumping plungers and being driven, in use, by an engine-driven cam, so as to drive a pumping stroke of the tappet and the associated plunger during which fuel within the associated pumping chamber is pressurised. Each tappet (22a, 22b) defines an internal volume (24a, 24b) for housing, at least in part, an associated return spring (34a) which drives a return stroke of the tappet and the associated plunger during which the associated pumping chamber is filled with fuel. A return circuit (50a, 50b, 52a, 52b, 54) is provided by which the internal volume (24a) of the first tappet (22a) is in constant communication with the internal volume (24b) of the second tappet (22b) so that fuel displaced from the internal volume during the pumping stroke of the first tappet fills the internal volume of the second tappet so as to aid the return stroke of the second tappet.

摘要： A fixing insert (10) for use in fixing a first part (50) to a second part (60) is disclosed. The fixing insert (10) comprises a body (12) having first and second ends (14, 16) and defining a body axis (A) extending therebetween. The body (12) comprises engagement means (18) for engaging a fastener, in use, and a plurality of anchor portions (20a, 20b, 20c) distributed along the body axis (A), each anchor portion (20a, 20b, 20c) extending laterally with respect to the body axis (A). The respective lateral extent (R A ) of each anchor portion (20a, 20b, 20c) is proportional to the distance between the respective anchor portion (20a, 20b, 20c) and the first end (14) of the body (12).
