摘要： In a valve device for a fuel tank, a condition of blowing out a fuel to an outside of a fuel tank can be prevented as little as possible. The valve device includes a valve opening for communicating inside and outside of the fuel tank; a valve chamber formed below the valve opening; and a float disposed inside the valve chamber to be movable up and down, and the valve chamber has a structure of positioning an open end below a support portion of the float having a passage portion for a fluid. An orifice is formed in the support portion, and by a notch portion formed in the valve chamber, an entrance of an orifice-ventilation path communicating with the orifice is formed at a side lower than the support portion and at a side upper than the open end.

摘要： In a valve device for a fuel tank, a fuel liquid level of filling-up fuel feed and an allowable fuel amount of additional fuel feed can be easily and appropriately changed by replacing only a part of components forming the valve device. A first valve chamber has a structure of positioning an open end below a support portion of a first float having a passage portion for a fluid. A second valve chamber includes a support portion of a second float having a passage portion for the fluid. The first valve chamber and the second valve chamber are formed by fitting a lower-portion including the support portion and the open end of the first float and the support portion of the second float relative to an upper-portion including a first valve opening and a second valve opening.

摘要： A valve device is attached to a fuel tank. The valve device includes a case including a vent valve port communicating outside of the tank at an upper portion, and including an inflow portion for a fuel below the vent valve port; and an upper floor body inside the case and rising by the fuel flowing into the case to be seated in the vent valve port. In a face portion facing a bottom portion of the upper float body in the case, an elastic piece is formed by a first arc-shaped split groove such that a center side of the face portion becomes a curvature inner side, and a second arc-shaped split groove formed such that a center of the face portion becomes a curvature inner side outside the first arc-shaped split groove. One portion of the elastic piece abuts against the bottom portion of the upper float body.
