The present disclosure relates to a solenoid valve having a ventilation structure, in which a connection passage for connecting a first space that is an operating space of an armature and a second space that is a lower space of a bobbin is formed on a bottom surface of a housing. The second space of the bobbin is connected with an outer space of the housing by a communication path. Accordingly, by connecting the first space that is the operating space of the armature with an outer space of the solenoid valve, a negative pressure can be avoided in the operating space of the armature, thus preventing the performance of the armature from being deteriorated.

Solenoid valve having ventilation structure

A solenoid valve is provided. The solenoid valve is used to control the flow of fluid in various technical fields and products including a transmission installed in a vehicle. The solenoid valve includes a ventilation passage connecting in flow communication the interior and exterior of an operating chamber, configured to operate an armature.
