    • PROBLEM TO BE SOLVED: To allow assembly work easy while maintaining mutual connection strength of respective members, in an exhaust valve device for a fuel tank.SOLUTION: The exhaust valve device includes: a cylindrical top structure composed of a first casing 2 and a second casing 3; a bottom structure (a third casing 4) which has a cylindrical shape with a top end and a bottom end opened, and in which the bottom end of the top structure is fitted inside the top end; and a float valve 5 which is supported between the top structure and the bottom structure so as to be vertically movable. In the top structure, a plurality of first locking claws 48 is projected, at intervals in a circumferential direction, in an outer circumferential face of the bottom end fitted into the bottom structure. The bottom structure includes: a plurality of first locking holes with which each of a plurality of first locking claws is engaged; and a long hole 59 which is formed at a position separated from the top end edge of the bottom structure between adjoining two holes of first locking holes, and which penetrates from an outer circumferential face to an inner circumferential face of the bottom structure and extends in upper and lower directions.
    • 要解决的问题:为了使组装工作容易,同时保持各个部件的相互连接强度,在用于燃料箱的排气阀装置中。 排气阀装置包括:由第一壳体2和第二壳体3构成的圆筒形顶部结构; 底部结构(第三壳体4),其具有顶端和底端打开的圆筒形状,并且顶部结构的底端装配在顶端内部; 以及浮动阀5,其被支撑在顶部结构和底部结构之间以便可上下移动。 在顶部结构中,多个第一锁定爪48在装配到底部结构中的底端的外周面中以周向间隔地突出。 底部结构包括:与多个第一锁定爪中的每一个接合的多个第一锁定孔; 以及长孔59,其形成在与第一锁定孔的相邻的两个孔之间的与底部结构的顶端边缘分离的位置,并且从孔的外周面向内周面贯通并延伸 上下方向。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a full tank control valve device that can refuel, even if a liquid level in a fuel tank changes largely when a vehicle mounting the fuel tank performs turn traveling, etc. immediate before the refuelling, and can prevent overflow of the fuel from a fill opening at the first refuelling.SOLUTION: A casing 10 includes a container 36 in which a float valve 50 is disposed. When the float valve 50 is closed, the casing keeps the float valve in a closed state for a relatively long period of time. A sub-float valve 80 is provided below the container 36 in the casing 10, and is closed by floating on fuel upon turning of a vehicle or an automatic stop of first refueling. When the first refueling is completed, air in the sub-float valve 80 is discharged, and the sub-float valve loses its floating function.
    • 要解决的问题:即使在燃料箱安装燃料箱的车辆在加油之前立即进行转弯行驶等时,即使燃料箱中的液位变化很大,也可以提供一种能够加油的全箱控制阀装置,以及 可以防止在第一加油时燃料从填充开口溢出。 解决方案:壳体10包括其中设置有浮阀50的容器36。 当浮阀50关闭时,壳体将浮阀保持在关闭状态较长时间。 副浮球阀80设置在壳体10的容器36的下方,在车辆转动或自动停止第一次加油时通过浮动而关闭。 当第一加油完成时,副浮阀80中的空气被排出,并且副浮阀失去其浮动功能。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a fuel shutoff valve which has a simple construction and prevents liquid fuel from flowing outside by promptly returning it to a valve chamber, even if the liquid fuel flows out from a connection path.SOLUTION: The fuel shutoff valve 10 includes: a casing body 30 with the valve chamber 30S, in which a connection hole 31a that is an opening to a valve chamber 30S side in a ceiling wall 31 is formed; a lid body 40 which forms a tube body section 42 for forming a tube passage 42a; and a float 52 accommodated in the valve chamber 30S. In the upper part of the casing body 30, a liquid shielding member, which forms a stay chamber for temporarily stemming the liquid fuel that flows out from the connection hole 31a, and a plurality of partition pieces, which are formed to be projected in an upper face of the ceiling wall 31 in the stay chamber, are provided. Each partition piece is radially disposed to be coupled with the liquid shielding member from an almost center of the connection hole 31a, wherein the stay chamber is divided into a plurality of stay compartments.
    • 要解决的问题:即使液体燃料从连接路径流出,也可以提供一种结构简单,防止液体燃料迅速返回到阀室的液体燃料流出的燃料截止阀。 解决方案:燃料截止阀10包括:具有阀室30S的壳体主体30,其中形成有与天花板壁31中的阀室30S侧开口的连接孔31a; 盖体40,其形成用于形成管道42a的管体部42; 以及容纳在阀室30S中的浮子52。 在壳体主体30的上部,形成有用于暂时停止从连接孔31a流出的液体燃料的停留室的液体屏蔽部件和形成为突出于其中的多个分隔件 设置在停留室中的顶壁31的上表面。 每个分隔件径向设置成与液体屏蔽构件从连接孔31a的大致中心耦合,其中保持室被分成多个停留室。 版权所有(C)2013,JPO&INPIT
