Title:
FILL-UP CONTROL VALVE DEVICE
Document Type and Number:
Japanese Patent JP2015180567
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fill-up control valve device that allows refueling even though a surface level in a fuel tank changes largely when a vehicle equipped with the fuel tank makes a turn or the like immediately before the refueling, and that can prevent overflow of fuel from a refueling port at the time of initial refueling.SOLUTION: A casing 10 includes a container 36 in which a float valve 50 is disposed. When the float valve 50 is closed, the casing keeps the float valve in the closed state for a relatively long period of time. A sub-float valve 80 is provided below the container 36 in the casing 10, and is closed by floating on fuel at the time of a turn of a vehicle or an automatic stop of first refueling. When the first refueling is completed, air in the sub-float valve 80 is discharged, and the sub-float valve loses its floating function.
