    • PROBLEM TO BE SOLVED: To provide a fuel tank ventilating device having simple construction without the need for a complicated and long pipe or a rising pipe partially subjected to bending work.
      SOLUTION: The fuel tank ventilating device comprises a fuel cut-off device 10, and a connection pipe CP for connecting the fuel cut-off device 10 to a canister CS. The fuel cut-off device 10 has a first fuel cut-off valve 20, a second fuel cut-off valve 40, and a positive pressure valve 70, and it is connected to the canister CS with a first flow path pipe CP1 and a second flow path pipe CP2 connected to a third flow path pipe CP3 via a connection part CP-J. In such a first liquid immersed condition that the first fuel cut-off valve 20 is immersed in liquid, fuel residing in the first flow path pipe CP1 is returned to a fuel tank FT in accordance with a pressure difference between tank inner pressure and pipe inner pressure applied to the fuel in the first flow path pipe CP1. In such a second liquid immersed condition that the second fuel cut-off valve 40 is immersed in liquid, fuel leaking into the second flow path pipe CP2 does not arrive at the connection part CP-J.

    • PROBLEM TO BE SOLVED: To provide a float valve device, in a closed state that a float has been raised by rising of a fuel liquid level, capable of being immediately opened when the fuel liquid level is lowered again. SOLUTION: The float valve device 10 comprises a housing, the float 50 stored in the housing , a movable valve 70 for blocking an opening part 32 by contacting a valve seat 32a when the float 50 surfaces to predetermined height, and a holding frame 60 having a frame shape surrounding the outer periphery of the movable valve 70 and mounted to the outer periphery of an upper part of the float 50 so as to hold the movable valve 70 with a predetermined distance to the float 50 to rise/descend and to make slanting movements. A convex part 90 biased to the circumferential direction is formed at a contact part between the holding frame 60 which regulates height of rising/descending of the movable valve 70 to the float 50 and the movable valve 70. When the float 50 is lowered in the valve-closing state, the convex part 90 contacts first to give descending force to the movable valve 70. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种浮阀装置,处于关闭状态,即当燃料液位再次降低时能够立即打开的浮子已经升高了燃料液位。 浮球阀装置10包括壳体,储存在壳体中的浮子50,用于当浮子50表面到预定高度时通过使阀座32a接触而阻止开口部32的可动阀70以及保持 框架60具有围绕可动阀70的外周的框架形状,并且安装到浮子50的上部的外周,以便将可移动阀70保持与浮子50的预定距离上升/下降,并且 做出倾斜的动作。 在将可动阀70的上升/下降高度与浮子50和可动阀70进行调节的保持框架60之间的接触部分形成在圆周方向上偏置的凸部90.当浮子50在 阀关闭状态,凸部90首先接触,向可动阀70施加下降力。版权所有(C)2009,JPO&INPIT
