A longitudinal cross-sectional view showing the tank when refueling, Fig. 4 is a cross-sectional view showing the bearing part of the valve and its vicinity, Fig. 5 is an enlarged cross-sectional view taken along the - line in Fig. 1, and Fig. 6 shows the operating mechanism of the valve. The perspective view and FIGS. 7 to 10 are explanatory diagrams of the operation of the operating mechanism, respectively. FIG. 7 shows the normal state or when refueling the main fuel tank, and FIG.
Figure 9 shows when the lock bar and the second lock lever are disengaged, and Figure 9 shows when the auxiliary fuel tank is being refueled;
Figure 0 shows the state immediately before the first lock lever and the second lock lever are engaged. Further, FIG. 11 is an enlarged explanatory view of section A in FIG. 10, and FIG. 12 is a sectional view showing a bearing portion of a valve in a conventional switching valve. 2...

Claims

[Scope of Claim for Utility Model Registration] (1) A valve equipped with an inlet that communicates with the fuel supply pipe, a main stream outlet that communicates with the main fuel tank side fuel supply pipe, and a auxiliary outlet that communicates with the auxiliary fuel tank side fuel supply pipe. a main body, and a flap that is disposed at a branching point between the main stream outlet and the sub-outlet and rotates about one side as a fulcrum to selectively switch communication between the inlet and the main-stream outlet or the sub-outlet; A refueling switching valve, which has an operating mechanism that is attached to the valve body to rotate the valve from the outside and has a rod that is the final transmission member of the operating force connected to approximately the center of the valve. A support structure that allows a rotational support part of the valve set in the valve body to move in a direction substantially perpendicular to a valve seat formed on the side of the secondary outlet when opening and closing the secondary outlet of the valve. Refueling switching valve. (2) A valve body having an inlet communicating with the fuel supply pipe, a main stream outlet communicating with the main fuel tank side fuel supply pipe, and a sub outlet communicating with the sub fuel tank side fuel supply pipe; a flap-type valve disposed at a branching point from the outflow port and selectively switching communication between the inflow port and the main flow outlet or the sub-flow port by rotating about one side as a fulcrum; In the refueling switching valve, the refueling switching valve has an operation mechanism that is attached to the valve body for rotational operation from the outside, and a rod that is the final transmission member of the operation force is connected to a substantially central portion of the valve, It is rotatably mounted, and when the valve is pressed with a predetermined force against the valve seat of the sub-outlet when the operating mechanism operates the valve in the sub-outlet closing direction, the operating mechanism moves in the sub-outlet opening direction. a lock lever that holds the valve in a closed position by engaging with a portion of the operating mechanism to prevent movement of the operating mechanism; and a lock lever that rotates the lock lever engaged with the operating mechanism in a direction to disengage the valve. and a disengagement release means for releasing the pressed state against the valve seat.
