    • A float valve for a fuel tank, which comprises an upper float chamber, a middle chamber, and a lower float chamber housed in a case that is fixed to the upper wall of a fuel tank. The upper float chamber includes a first communication hole that directly communicates with an air bleed duct. The upper float that can block that first communication hole when the tank is full. The middle chamber includes a third communication hole communicating with the lower float chamber which has a first air hole located at a position corresponding to the desired fuel level for a full tank. The lower float chamber includes a lower float than can block the third communication hole, and a second air hole which is located bellow the lower float. Because the air passages and float activation allow air to be vented as the fuel level rises in the tank fueling proceeds smoothly and drastic increases in internal pressure, that will stop fueling prematurely can be avoided.
    • 一种用于燃料箱的浮阀,其包括容纳在固定到燃料箱的上壁的壳体中的上浮子室,中间室和下浮子室。 上浮体室包括与排气管直接连通的第一连通孔。 当坦克满时,可以阻塞第一个通信孔的上浮子。 中间室包括与下浮子室连通的第三连通孔,其具有位于对应于满罐的期望燃料水平的位置处的第一气孔。 下浮子室包括比可以阻塞第三连通孔的下浮子,以及位于下浮子下方的第二气孔。 因为空气通道和浮动启动允许空气在储油罐燃料中的燃料水平上升时进行排气,因此可以平稳地进行并且可以避免过早地停止加油的内部压力的急剧增加。

    • A fuel cap 1 for controlling the pressure within a fuel tank which has improved sealing properties between a valve member 43 of a pressure control valve 41 and a seat surface 35. The pressure control valve 41 opens and closes a flow path hole 33 in a cap body 5 so as to control the pressure within the fuel tank. In this pressure control valve, the valve member 43 is seated on the seat surface 35 in accordance with the force of a spring 71 and the pressure within the fuel tank. The valve member has a disk portion 49 which is flexed when the valve member receives a large pressure in a valve closing direction. An outer lip 57 and an inner lip 58 are formed on the disk portion 49. The outer lip 57 is seated on the seat surface 35 when the pressure within the fuel tank reaches a predetermined pressure. When the pressure increases further, the disk portion 49 is flexed, so that the inner lip 58 is also seated on the seat surface 35. Therefore, when the pressure in the valve closing direction becomes great, the double lip portion is seated on the seat surface 35, thereby providing enhanced sealing properties.
