Abstract (en)

The pump comprises a body (2) provided with an axial inner chamber (3) communicating with a delivery pipe; a plunger (9) mobile within the chamber (3) and provided with a shaped-profile groove (10) to vary the pumped fuel delivery rate on varying the angular position of the plunger (9); an inlet bore (4) radially traverses said body (2) and opens into the inner chamber (3), said bore (4) communicating directly with the fuel feed pipe; a spill bore (5) which is distinct and separate from the inlet bore (4) radially traverses said body (2) to open into the inner chamber (3), said bore (5) communicating directly with the fuel spill pipe; a valve (8) is disposed in the spill bore (5) to allow fuel to leave but to prevent it returning to the chamber (3).
