Title:
LIQUID FUEL CAPTURING UNIT
Document Type and Number:
Japanese Patent JP2015175324
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid fuel capturing unit for positively capturing liquid fuel and returning it to a fuel tank.SOLUTION: A liquid fuel capturing unit 9 allows fuel vapor to pass and captures liquid fuel. A case in this invention defines a plurality of volume chambers 50 formed as a cavity segment at a flow passage to cause liquid fuel to be accumulated therein; a communication part 60 for communicating the plurality of volume chambers 50 in series at their upper segments; and a return passage 70 opened at a bottom part of each of the plurality of volume chambers 50 to return liquid fuel accumulated at the volume chambers 50 to a fuel tank 3. Further, the liquid fuel capturing unit 9 has a return valve 80. The return valve 80 closes the return passage 70 when a height of liquid surface of liquid fuel in the fuel tank 3 exceeds a prescribed height. The return valve 80 opens the return passage 70 when a height of liquid surface of liquid fuel in the fuel tank 3 is lower than a prescribed height. With this arrangement, fuel is returned from the plurality of volume chambers 50 to the fuel tank 3.
