Abstract

PURPOSE:To make starting easy by providing four nozzles in the valve casing of an opening-closing valve interposed in a supply system of gasoline fuel so as to open and close the nozzles by the rotation of the valve disc and making that the fuel in a carbureter is discharged possible at the time of shutdown for a long time. CONSTITUTION:An opening-closing valve 1 provided in a supply system of gasoline fuel has a valve casing 21 with a receiving nozzle 22, a supply nozzle 23, an exhaust nozzle 24 and an ejection nozzle 25 to which a receiving pipe 4 reaching a gasoline tank 2, a supply pipe 6 reaching a carbureter 5, an exhaust pipe 8 reaching the bottom portion 7 of the carbureter and an ejection pipe 10 with opening one end are respectively connected. A valve 30 to which a handle for valve rotation 37 is attached is stored rotatably in the valve casing 21. The valve 30 has a L-type floating hole 31 which can intercommunicate with the receiving and supply nozzles 22, 23, a floating hole 33 intercommunicating with the exhaust nozzle 24 and a floating hole 32 which intercommunicates with the floating hole 33 and can intercommunicate with the ejection nozzle 25.
