ABSTRACT:
The hydraulic head especially for an "in line" injection pump, comprises a cylinder forming a pump chamber, in which a pump piston moves, having at least one fuel supply orifice formed in its cylindrical wall. The hydraulic head has a deflector element situated axially at the level of this supply orifice to deflect a jet of fuel capable of emerging from said orifice. A delivery connector is connected to the cylinder, and is constituted by an elastic ring of cylindrical form. The ring is open and has two ends arranged to come into contact with one another, said ends being separable from one another.
