Claims

[Scope of utility model registration request]

(1) A predetermined plunger block is reciprocated according to the excitation force induced by intermittent energization of the excitation coil, and the first port is opened to the atmosphere and the second port connected to the predetermined air pressure source side. In the electromagnetic valve, the solenoid valve is configured to alternately communicate with a third port in order to perform switching control, and an expansion chamber is provided outside the third port, and the valve is communicated with the atmosphere through the expansion chamber. and a predetermined foam is housed in the expansion chamber to reduce operating noise of the plunger block discharged into the atmosphere through the third port.

(2) A utility model registration according to claim 1, wherein a second foam body is disposed outside the air communication hole of the expansion chamber, and ventilation into the expansion chamber is performed through the second foam body. solenoid valve.
