Abstract (en)
[origin: EP1167723A2] An advance arrangement comprises an advance piston (12) which is slidable within a first bore (14), the advance piston (12) cooperating, in use, with a cam arrangement of a fuel pump to adjust the timing of fuel delivery by the pump. A servo-piston (24) is slidable within a further bore (22) provided in the advance piston (12), a light load piston (26) being moveable relative to the advance piston (12) against the action of a light load control spring (28). A servo-control spring (34) is engaged between the light load piston (26) and the servo-piston (24) and a seal arrangement (30, 32) comprising at least one separate seal member, is arranged to form a substantially fluid tight seal between the servo-piston (24) and the light load piston (26). The servo-piston (24) may include a removable region (40), whereby removal of the region (40) permits the advance characteristics of the advance arrangement for light load conditions to be varied. <IMAGE>
