Abstract
The hydraulic head comprises a cylinder forming a pump chamber and comprising at least one fuel supply orifice formed in its cylindrical wall. A pump piston is adapted to move in said cylinder, and a delivery connector is connected to the cylinder. This connector is provided externally with a shoulder adapted to constitute an axial stop for the hydraulic head, against a support surface of the pump casing comprising housings adapted to receive said hydraulic heads. The delivery connector, comprises, in addition, internally, a delivery valve, the end portion of the cylinder turned towards the delivery connector comprising, on its outer surface, fixing means adapted to cooperate with complementary fixing means provided on the inner surface of a housing of the delivery connector adapted to receive said end portion of the cylinder. Thus, in the fully assembled hydraulic head, said cylinder is directly suspended on the delivery connector.
