ABSTRACT:
A three-way valve comprises a control mechanism which is disposed within a valve main body. The control mechanism is provided for bringing a first main valve in contact with a first valve seat of the valve main body and simultaneously separating a second main valve by a great distance from a second valve seat of the valve main body when the pressure of a first valve chamber is higher than a pressure of a second valve chamber, thereby communicating a second inlet port with an outlet port. Otherwise, the control mechanism is provided for bringing a second main valve in contact with the second valve seat and simultaneously separating the first main valve by a great distance from the first valve seat when the pressure of the second valve chamber is higher than the pressure of the first valve chamber, thereby communicating a first inlet port with the outlet port.
