Title:
FUEL TANK FLOAT VALVE
Document Type and Number:
WIPO Patent Application WO/2017/042989
Kind Code:
A1
Abstract:
A refueling control valve 3 provides a fuel tank float valve. A plurality of cases 31, 51 provide tubes which are suspended in a fuel tank. When refueling occurs, fuel rises up through the tubes. A main float valve 21 prompts termination of the refueling operation by closing a ventilation passage when the fuel reaches an upper portion of the main float valve 21. A sub-float valve 23 prompts a transition from high-volume refueling to low-volume refueling by temporarily closing the ventilation passage before the fuel reaches the main float valve 21. A movable valve body 54 includes a plurality of second air reservoirs 62. The plurality of second air reservoirs 62 are arranged in a ring. Air accumulates in each of the plurality of second air reservoirs 62 even if the refueling control valve 3 is inclined, and even if the liquid surface fluctuates. A seal member 66 is pressed against a valve seat 52 by means of the buoyancy of the plurality of second air reservoirs 62.
