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.
