Transfer pump for high-pressure petrol injection of the type including a piston () which delivers oil into a deformable element such as a bellows (), the deformations of the bellows () in a cylindrical chamber () filled with fuel causing a pumping effect whereby the fuel is pumped towards a rail () supplying high-pressure injectors, wherein elements are arranged for diverting some or all of the oil pumped by the piston () towards a chamber () without pressuring it so as to determine at will the useful stroke of the piston () and hence the quantity of fuel pumped at high pressure towards the rail ().
