Solenoid valve

A solenoid valve comprising:

• a valve seat having a valve flow path;
• a plunger configured to be movable in a direction toward or away from the valve flow path;
• a support member disposed at an end of the plunger facing the valve flow path, the support member having an insertion hole into which the valve seat is inserted;
• a spring member, the support member being connected to the spring member configured to elastically support a movement of the plunger;
• a valve member seated in the support member, the valve member configured to cover the insertion hole and selectively open or close the valve flow path according to the movement of the plunger;
• an inclined guide surface provided along a periphery of the valve seat;
• and
• an inclined recess provided in an inner wall surface of the insertion hole facing the inclined guide surface,
• wherein the inclined recess and the inclined guide surface collectively define a movement path that communicates with the valve flow path;
• wherein one end of the insertion hole, which is adjacent to the valve member, has a first diameter, and an other end of the insertion hole has a second diameter larger than the first diameter, and
• wherein the valve member has a diameter larger than the first diameter and smaller than the second diameter.
