Abstract (en)

A fuel-supply system (1) for an internal-combustion engine has a high-pressure pump (7) that receives fuel from a low-pressure pump (7) through a pipe (10) provided with a solenoid valve (27) of an on-off type; the solenoid valve has an open/close element (40) that translates along an axis (33) between an opening position and a closing position under the opposite actions of an electric actuator (43) and a spring (42); in the closing position, under the thrust of the spring (42), the open/close element (40) closes an axial inlet (32) and inhibits passage of fuel towards an outlet (38), which is provided in a radial direction and communicates with at least one intake valve (25) of the high-pressure pump (7).
