Claims

[Scope of claims for utility model registration] (1) A coil, a magnetic circuit surrounding this coil,
A plunger valve slidably fitted into the magnetic circuit via a guide, a valve seat having an inlet port on the bottom of the plunger valve, a case constituting the magnetic circuit and having an outlet port, coaxial with the plunger valve. The electromagnetic valve includes a core having a fluid relief hole in the core and performs an opening/closing operation between the plunger valve and the valve seat, and includes a cover with a hole that covers the fluid relief hole in the core and is connected to the fluid relief hole in the core. A solenoid valve characterized by having a porous soundproofing material interposed in the part where the noise is caused. (2) The solenoid valve according to claim 1, wherein the cover with holes is a rubber boot.
