したことを特徴とする２段作動型電磁弁。 A solenoid valve comprising a main valve body slidably provided in the valve chamber to move toward and away from a valve seat that communicates with a secondary flow path provided at the bottom of a valve chamber having a primary flow path opening, the main valve The body has an auxiliary passageway formed on the back side from the auxiliary valve seat to the secondary flow path, the flow resistance of which is greater than the flow resistance of the leakage path from the primary flow path side to the back space of the main valve body. A two-stage operating type characterized in that a plunger having a sub-valve body at its tip that moves toward and away from the sub-valve seat and the main valve body are coupled to be movable within a limited distance range. solenoid valve.
