蒸发燃料处理装置
摘要：
本发明提供一种蒸发燃料处理装置。该蒸发燃料处理装置通过设置在燃料箱的压力调整作用不正常地发挥作用时用的补充作用，即便在燃料箱的压力调整作用不正常地发挥作用时，也抑制燃料箱的内压朝向对于燃料箱而言的极限压力变动。该蒸发燃料处理装置使燃料箱(15)内的蒸发燃料吸附于吸附罐(21)，而且将该吸附了的蒸发燃料吸入到发动机主体(11)，其在连接燃料箱(15)和吸附罐(21)的路径上包括开闭阀(封闭阀)(24)，而且包括用于检测燃料箱(15)的内压的压力传感器(26)，其中，该蒸发燃料处理装置包括开阀部件，在由压力传感器(26)检测出的压力达到为了保护燃料箱(15)而预先设定好的设定压力时，该开阀部件打开开闭阀(24)。
摘要（英）：

The invention provides a fuel vapor processing apparatus which can prevent an internal pressure of a fuel tank from becoming out of a predetermined range even in the case that a pressure regulating valve of the fuel tank does not properly function through the supplement effect used when the pressure regulating valve of the fuel tank does not properly function. The fuel vapor processing apparatus makes the vapor fuel in the fuel tank (15) to be adsorbed in an absorption canister (21). The adsorbed vapor fuel is sucked into an engine main body (11). An opening valve (a closing valve) (24) may be disposed in a passage connecting the fuel tank (15) and the absorption canister (21). A pressure sensor (26) for detecting the inner pressure of the fuel tank (15) is also disposed in the passage, wherein the fuel vapor processing apparatus includes a valve opening member which opens the opening valve (24) when the pressure detected by the pressure sensor (26) reaches a pre-set pressure for protecting the fuel tank (15).
