摘要： An inner diameter of a filler tube is formed smaller than that of a filler neck of a tank main body. Hence, a clearance is thus difficult to be created between inner peripheral surface of the filler tube and the fuel stream which flows through the filler tube upon supply of fuel, and also leakage of vapor fuel from a fuel filler port can be avoided. In addition, a cylindrical insert whose inner diameter is formed to be substantially equal to its of the filler tube is provided in a neck portion of the filler hose. Accordingly, there exists no portion where the inner diameter is largely changed in the filler neck portion, whereby generation of turbulent flow of the supplied fuel and reduction in a flow rate can be suppressed to their maximum and thus fuel supply performance can be enhanced.
摘要翻译：填充管的内径形成为小于罐主体的填充物颈部的内径。因此，在供给燃料时，在填充管的内周面和流经填充管的燃料流之间难以形成间隙，能够避免蒸汽燃料从燃料加注口的泄漏。此外，在填充软管的颈部设置有内径形成为与填充管大致相等的圆柱形插入件。因此，在填充颈部不存在内径大的变化的部分，能够将所供给的燃料的湍流的产生和流量的减少抑制到最大限度，能够提高燃料供给性能。

摘要： A canister structure for absorbing fuel vapor in the fuel tank and supplying the fuel vapor into the engine together with purge air is provided. The canister structure includes a canister body filled up with absorbents for absorbing the fuel vapor, a purge pipe connected to the canister body for introducing the purge air into the canister body and a separator for removing moisture contained in the purge air. To the separator, the purge pipe is connected downwardly. The separator is provided on the bottom side with an air inlet of which diameter is larger than that of the purge pipe. With the above-mentioned arrangement, since the separator is so formed as to have a diameter larger than that of the purge pipe, it is possible to reduce a flowing speed of the purge air by means of the separator, so that moisture contained in the purge air can be trapped and eliminated by the separator certainly.
摘要翻译：提供一种用于吸收燃料箱中的燃料蒸气并将燃料蒸气与吹扫空气一起供应到发动机中的罐结构。罐结构包括填充有用于吸收燃料蒸气的吸收剂的罐主体，连接到罐体的吹扫管，用于将吹扫空气引入到罐主体中，以及用于除去吹扫空气中所含的水分的分离器。清洗管向分离器下方连接。分离器设置在底侧，其空气入口的直径大于吹扫管的直径。采用上述结构，由于分离器的直径大于吹扫管的直径，所以可以通过隔板降低吹扫空气的流动速度，从而使包含在吹扫空气可以被分离器捕获并消除。

摘要： 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.
摘要翻译：燃料箱系统包括用于容纳燃料的罐体，用于设置所述燃料部件的罐，与罐体连接并形成用于向罐体供给燃料的通道的填充管，具有第一室的排气侧止回阀以及由隔膜隔开的第二室，将通气侧止回阀的第一室与加料管的上部连接的信号管，用于经由排气口的第二室将罐体与罐连接的排气侧管并且用于当填充燃料时通过第二室将容纳在罐主体中的含有燃料成分的气体体引入到罐中，以及设置在信号管上的在加料管侧的上部的孔，具有可以防止燃料从加料管侧渗透到信号管侧的内径和长度。因此，通过孔口的功能，可以控制燃料进入信号管的渗透，从而保持排气侧止回阀的功能。
