    摘要： The invention relates to a method for testing the tightness of a fuel supply system of a motor vehicle, comprising a volume-changing element provided in the fuel tank, the volume of which volume-changing element is in contact with the environment, whereas the fuel tank is customarily sealed off against the environment by means of a valve unit. For testing the tightness, a differential pressure with respect to environment is generated in the tank by means of a gas conveying device, sequentially and thus not simultaneously, the volume-changing element being sealed off against the environment, and the volume changing element not being sealed off against the environment, a differential pressure with respect to environmental pressure is generated in the volume-changing element or in the tank. Said differential pressures are maintained and monitored over a certain period of time, and if after this period of time, the differential pressures still exceed a certain threshold value, a sufficient tightness of the fuel supply system is concluded.

    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 float 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.

    摘要： A valve device includes a float body and a valve body provided in an upper portion of the float body to obliquely move. The valve body includes a seal portion that closes a valve opening formed in a case when the float rises, an engaging portion serving as a linkage portion with respect to the float body, and an abutting portion that abuts on a vicinity of the valve opening when inclining obliquely. An area of the abutting portion in the horizontal direction is made smaller than that of the seal portion such that the abutting portion laterally protrudes from the seal portion.
