ABSTRACT:
A check valve 30 set in a fuel tank 10 that dispenses incoming cooler fuel over a wide area that also reduces development of the fuel vapor in a gas tank body 12 when filling the tank. The check valve 30 is attached to one end of an inlet pipe 22 for introducing a supply of fuel into the tank body 12, and includes a housing 32 with a plurality of outlets 38, a valve member 40, and a spring 50. The plurality of outlets 38 are arranged at substantially equal intervals along a circumferential direction of the housing 32. The check valve 30 is generally set in its normally closed position by the pressing force of the spring 50 in order to prevent the fuel vapor in the tank body 12 from being discharged to the atmosphere even without a cap. The flow of fuel presses open the check valve 30 and is discharged out of the plurality of outlets 38 toward a wide area in the tank body 12, so as to cool down the fuel stored in the tank body 12, thereby reducing development of the fuel vapor.
