Abstract: An apparatus and method are disclosed for transmitting drive between a first and at least one further component. The apparatus includes an elongate shaft element extending along a respective longitudinal axis and comprising a first and further shaft region, each of which comprises a substantially cylindrical outer surface extending from a respective first and further side of a cam body region. The apparatus also includes a fluid communication pathway extending within the shaft element from a first end region of the shaft element to at least one outlet aperture in an outer surface of the first cylindrical region.

Abstract: The present invention relates to a high pressure fuel pump assembly (1) for an internal combustion engine. A follower roller (39) is provided for engaging a cam (41) provided on a rotatable driveshaft (43). A shoe (19), which is guided in a shoe guide (21) having a guide face (55), cooperates with the follower roller (39) for reciprocating a fuel pump plunger (3). The shoe (19) has an upper side (25) and a lower side (27); a part cylindrical recess (37) being formed on the lower side (27) for cooperating with the follower roller (39). At least one aperture (57, 59; 59'; 59", 61; 63) is provided in the shoe guide (21) and/or the shoe (19) to form at least one fluid pathway for maintaining fluid communication between the upper and lower sides (25, 27) of the shoe (19). The present invention also relates to a shoe (19) and a shoe guide (21).
