<p><P>PROBLEM TO BE SOLVED: To provide a three-way valve enabling automatic switching of passages in a valve housing without using an electromagnetic force or the like. <P>SOLUTION: A first equalizing chamber is formed on one axial end in the valve housing, a second equalizing chamber is formed on the other end, an energizing means for energizing a valve element in a closing direction of a passage running from an inlet port to a second outlet port is disposed within the first equalizing chamber, and an equalizing introduction passage for introducing part of a fluid flowing in from the inlet port is coupled to the second equalizing chamber, so that when the pressure of the fluid flowing in from the inlet port is lower than a predetermined pressure, a passage through which the fluid flowing in from the inlet port flows out from a first outlet port is formed in the valve housing, and when the pressure of the fluid flowing in from the inlet port is higher than the predetermined pressure, a passage through which the fluid flowing in from the inlet port flows out from the second outlet port is formed in the valve housing. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
