Zusammenfassung:	A high-pressure pump (1) for feeding fuel to an internal combustion engine has a pump body (2), at least one piston (4) and a transmission mechanism (3) which is able to impart a reciprocating movement to the piston (4) and has a shaft (9) with an eccentric portion (10) and a cup (12); the pump body (2) is formed by a main body (5) having a chamber (7) housing the shaft (9) and a head-piece (6), which is mounted on the main body (5), has a cylinder (14) housing the piston (4) and a cylindrical seat (15) housing the cup (12). L'invention porte sur une pompe haute pression (1) pour alimenter un moteur à combustion interne en carburant, laquelle pompe comprend un corps de pompe (2), au moins un piston (4) et un mécanisme de transmission (3) qui est apte à communiquer un mouvement de va-et-vient au piston (4) et comprend un arbre (9) avec une partie excentrée (10) et une coupelle (12) ; le corps de pompe (2) est formé par un corps principal (5) ayant une chambre (7) recevant l'arbre (9) et un chapeau (6), qui est monté sur le corps principal (5), et qui comprend un cylindre (14) recevant le piston (4) et un siège cylindrique (15) recevant la coupelle (12).
