<P>PROBLEM TO BE SOLVED: To provide a three-way electromagnetic valve, in which the size of an electromagnetic coil is reduced to suppress a pressure loss with a small amount even when a large amount of gas coolant or the like flows. <P>SOLUTION: The three-way electromagnetic valve includes: a valve body 2 comprising an inflow port 2a, a first outflow port 2b through which high-pressure side fluid outflows and a second outflow port 2c through which low-pressure side fluid outflows; a first valve seat 3 located between the inflow port and the first outflow port; a second valve seat 4 located between the inflow port and the second outflow port; first and second valve bodies 6, 7 opposite to each other via two valve seats; and an actuation member 9 interposed between both valve bodies; wherein the actuation member separates the second valve body from the second valve seat while the first valve body is seated on the first valve seat, the actuation member separates the first valve body from the first valve seat while the second valve body is seated on the second valve seat, the seating of the first valve body to the first valve seat is performed by means of an energizing means 12, the seating of the second valve body to the second valve seat is performed by means of movement of the second valve body accompanying electricity conduction to an electromagnetic coil 14a and, therein, the valve diameter of the first valve seat is set to be smaller than the valve diameter of the second valve seat. <P>COPYRIGHT: (C)2012,JPO&INPIT |
