したことを特徴とする電磁弁。 A solenoid housing made of a magnetic material and a spool housing made of a non-magnetic material are connected, a first sliding hole is formed in the solenoid housing, and a plunger made of a magnetic material is slidably fitted into the first sliding hole. A second sliding hole is formed coaxially with the first sliding hole in the spool housing, a spool operated by the plunger is slidably inserted into the second sliding hole, and the spool is slidably inserted into the solenoid housing. a yoke is formed in the yoke, a solenoid that generates a magnetic force that attracts the plunger toward the yoke is disposed around the solenoid housing, and a first communication path that communicates both ends of the first sliding hole in the plunger with each other; forming a second communication path in the spool that communicates both ends of the second sliding hole with each other;
A solenoid valve characterized in that a drain passage is formed in the spool housing and communicates with one end of the second sliding hole on the opposite side from the plunger.
