More Information
Summary:The pump (5) has a body (8) including at least a fuel compression chamber (22) and an actuating chamber (23) enclosing the actuating members of the pump (5). The on-off valve (37) has a shutter (38) sliding inside a hole (34) in the body (8) to close a fuel feed conduit (30). The shutter (38) is held in the closed position by a compression spring (42), which rests directly or indirectly on a shoulder (43) in the hole (34). In one embodiment, the spring (42) rests on the shoulder (43) via a perforated disk (44) held by a retaining ring, which clicks removably inside an annular groove (49) in the hole (34). In a further embodiment, the spring (42) rests directly on the shoulder (43).
