Abstract

Improvements introduced in piston pumps, in particular for fuel injection in engines, whose type of pumps have a rotary shaft, which communicates its rotation to a reciprocating displaceable axial piston, characterized by the fact that a This pump or its main shaft is combined with an auxiliary supply pump, so that the rotation of the first ensures the distribution of the second.
