Claim 12:
13. A three-way solenoid valve comprising:
a valve block including a valve chamber and a first port, a second port, and a third port fluidly communicating with the valve chamber;
an armature configured to provide an electromagnetic force;
a body including a first body having one side facing the armature and a hollow therein, and a second body having one side facing another side of the first body and a hollow therein;
a plunger of which at least a portion passes through the hollows inside the first body and the second body and of which one end is configured to be pressed by the armature so that the plunger moves; and
a flow path control assembly that is disposed inside the second body and includes a first opening/closing flow path, which allows the first port and the second port to fluidly communicate with each other or to be blocked from each other according to a magnitude of a force applied by the plunger, and a second opening/closing flow path which allows the second port and the third port to fluidly communicate with each other or to be blocked from each other according to the magnitude of the force applied by the plunger,
wherein the armature is configured to provide a first electromagnetic force, a second electromagnetic force that is greater than the first electromagnetic force, and a third electromagnetic force that is greater than the second electromagnetic force,
opening/closing states of the first opening/closing flow path and the second opening/closing flow path are controlled according to the electromagnetic force provided by the armature, and
when the armature presses the plunger using the third electromagnetic force, the first opening/closing flow path is opened and the second opening/closing flow path is closed.
