    • An apparatus for suppressing the purge of the evaporated fuel gas in the prior art has a chamber in the middle of the piping connecting between the input port and an external apparatus, for reducing the pulsation of fluid flow, for reducing the noise sound and mechanical vibration. The reduction effect can not be attained, when the chamber is not disposed at an antinode of vibration. And it is difficult to dispose the chamber just at such antinode. And such arrangement is not advantageous in layout designing and from point of view of fabrication cost. The problem is solved by a solenoid valve according to the present invention. The solenoid valve comprises an input port, to which a pressure is imposed, an output port to be connected with an external apparatus, a plunger for opening and closing a channel communicating the input port and the output port according to the current supplied to a coil for driving the plunger, wherein a chamber is disposed in the middle of the channel from the input port to the output port.
    • 用于抑制现有技术中的蒸发燃料气体吹扫的装置在连接输入口和外部设备之间的管道中间具有一个腔室,用于减少流体流动的脉动,以减少噪音和机械振动 。 当腔室没有设置在振动波腹下时,不能达到还原效果。 而且这个房间很难处理这样的波腹。 这种布置在布局设计和制造成本的观点上是不利的。问题是通过根据本发明的电磁阀来解决的。 电磁阀包括施加压力的输入端口,与外部设备连接的输出端口,用于根据提供给线圈的电流来打开和关闭连通输入端口和输出端口的通道的柱塞 用于驱动柱塞,其中,腔室设置在从输入端口到输出端口的通道的中间。
