Torna indietro

Abstract

The device comprises at least one cartridge (38) carrying a filtering body (37) and removably housed in a corresponding casing (41). The device further comprises a shut-off solenoid valve (27) for metering the fuel and a pressure control valve (32) of such fuel. The solenoid valve (27) and possibly also the control valve (32) are housed in a block (54) separate from the pump (7) and either fixed to or integrated with the casing (41) of the cartridge (38). The casing (41) is provided with a lid (46), on which a union (52) for the connection to a supply pipe (10) is fixed. The block (54) comprises two unions (62 and 72) to connect the solenoid valve (27) and the control valve (32) to the pump (7), and a group of internal pipes (63) to connect the solenoid valve (27) upstream of the valve (32) in the direction of flow of the fuel.
