HIGH-PRESSURE PUMP FOR FEEDING HIGH-PRESSURE FUEL TO AN INTERNAL-COMBUSTION ENGINE

摘要

A high-pressure pump (1) for feeding high-pressure fuel to an internal-combustion engine has a pump body (2) with a chamber (3) designed to house a mechanism for actuating at least one pumping member and a wall (9) provided with a hole (10) along an axis (A) and delimited by an inner surface (12) arranged around the axis (A), a shaft (4) rotating about the axis (A), a friction bearing (14) which is forced with an interference fit inside the hole (10) of the wall (9) of the pump body (2) and is completely contained inside the hole (10, 29).
