Abstract

Injection pump device comprising a body provided with radial bores where pistons are housed, an annular cam arranged around said body to cooperate with each of the pistons, appropriate means for rotating the body and the cam one with respect to the another in order to drive said pistons and an appropriate distributor to join successively to each of the five cylinders of a motor a central passage communicating with the set of the pump chambers limited by said pistons in their respective bores, said means being actuated and the distributor in synchronism with said motor, characterized in that said cam is a five-lobed annular cam cooperating with only three pistons, namely two pistons of equal and spaced sections at an angle equal to approximately 72 [deg.] and a piston of larger section that has equal angular separations in relation to the other two pistons, the section of the Finally piston substantially equal to 1.6 times the section of each of the other two pistons.
