Title:
燃料タンクの開閉装置
Document Type and Number:
Japanese Patent JP6965634
Kind Code:
B2
Abstract:
In an opening and closing device (100) for a fuel tank, a path forming part (20) forms a fuel path (100P) along which supplied liquid fuel is guided to the fuel tank. A first valve mechanism (10) arranged at the path forming part (20) opens and closes a filling opening (104). A second valve mechanism (30) opens and closes an insertion path (100Pn) for a fuel nozzle (FN) at the end of the insertion path (100Pn) in the most upstream area of the fuel path (100P). In a non-filling situation in which the first valve mechanism (10) closes the filling opening (104), passage of air between an insertion path communication hole (51) and an outside air passage hole (53) is encouraged. In a filling situation in which the fuel nozzle (FN) makes the first valve mechanism (10) open the filling opening (104), passage of air between the insertion path communication hole (51) and the outside air passage hole (53) is interrupted. Therefor the opening and closing device (100) for the fuel tank prevents or reduces discharge of fuel in a fuel filling period while ensuring air permeability in a non-filling period.
