Fuel dispenser valve for petrol, especially diesel fuel pump, - has non-ferromagnetic housing and pipe, solenoid valve, permanent magnetic system, ferromagnetic adjustment and spindle

摘要

The valve housing (2) and pipe (3) are made of non-ferromagnetic material. The valve housing contains a mechanism for operating a sensor pipe (4) and an automatic stop to the fuel flow. After the flow has been stopped, the remaining fuel is discharged into the vehicle's tank via the orifice (6) of the pipe. A solenoid valve forming a drip-stop valve (7) is positioned in the orifice of the pipe, with a permanent magnet system and a valve body with annular seating. The valve body has a spindle which has a ferromagnetic adjustment on the side of the permanent magnet system. The spindle and adjustment are contained in a housing around which the fuel circulates. Between the adjustment and flange on the valve housing is a part-lifting return spring for the valve body.
