    • The fuel tank system comprises a tank body for containing fuel therein, a canister for disposing said fuel component, a filler tube connected with the tank body and forming a channel for supplying fuel to the tank body, a vent side check valve having a first chamber and a second chamber separated by a diaphragm, a signal tube connecting the first chamber of the vent side check valve with the upper part of the filler tube, a vent side tube for connecting the tank body with the canister via the second chamber of the vent side check valve and for introducing a gaseous body containing fuel component in the tank body to the canister via the second chamber when filling fuel, and an orifice for the signal tube, provided on the upper part of the signal tube on the filler tube side and having such an inside diameter and a length that may prevent the fuel permeation into the signal tube side from the filler tube side. Therefore, by the functions of the orifice, the permeation of the fuel into the signal tube can be controlled thus to maintain the functions of the vent side check valve.

    • A fuel chamber provided in a fuel tank for an automotive vehicle in order to effectively prevent a temperature of a fuel within a fuel tank from ascending not so as to generate a vapor due to a fuel returned to the fuel chamber end from an engine is mainly disclosed. In a typical fuel chamber, a fuel chamber main body, a jet nozzle member having a front end portion inserted into a hole portion communicating an inner portion with an outer portion of the fuel chamber main body, a cover body forming a pressure reduction chamber decompressed in response to that the jet nozzle member injects a return fuel to the fuel chamber main body through the hole portion, and a tubular circulating member circulating a fuel within the fuel chamber main body are provided. The fuel stored within the fuel tank is introduced into the fuel chamber main body and the fuel within the fuel chamber main body is circulated in response to that the jet nozzle member injects the return fuel into the fuel chamber main body.

    • A chamber structure is provided which is able to flow down fuel smoothly at a desired flow rate. A chamber main body is fixed onto an inner bottom 1a of a fuel tank of a vehicle, and a suction port of a fuel pump is inserted into an inside of the chamber main body. A through hole is formed in a peripheral wall of the chamber main body. A fuel tank side through hole for connecting an inside of the fuel tank and a negative pressure chamber being connected to the first through hole is arranged in a vicinity of the inner bottom of the fuel tank. An inlet port for passing return fuel into the inside of the fuel tank is faced to the negative pressure chamber. A recirculation funnel which has an upper end opening directed to the inside of the chamber main body at a position lower than an upper edge of the chamber main body is formed to extend upward from the negative pressure chamber.A peripheral length of the upper end opening of the recirculation funnel is set longer than that of the lower edge opening of the recirculation funnel directed to the negative pressure chamber.
    • 提供了一种室结构,其能够以期望的流速平稳地下流燃料。 室主体固定在车辆的燃料箱的内底1a上,并且燃料泵的吸入口插入室主体的内部。 在室主体的周壁形成有通孔。 在燃料箱的内底部附近设置有用于连接燃料箱内部的燃料箱侧通孔和与第一通孔连接的负压室。 用于使返回燃料进入燃料箱内部的入口面向负压室。 形成从负压室向上方延伸的具有朝向室主体内侧的上端开口的再循环漏斗,该上端开口位于比室主体的上边缘低的位置。 再循环漏斗的上端开口的周长设定得比指向负压室的再循环漏斗的下边缘开口长。
