| 摘要 |
The present invention provides a three-way solenoid valve with high reliability, capable of switching a flow channel for a refrigerant while securing an amount of the refrigerant under an environment with a great differential pressure without an increase in the size of an electronic coil or the like. The three-way solenoid valve comprises: a valve main body (2) having a via hole (2k) connected to a back pressure chamber (2eb) formed on an opposite side to a second valve sheet (4) of a second valve body (7); a third sheet (5) positioned between the via hole (2k) and a second discharge opening (2c); a third valve body (8) movably arranged to be in contact with a third valve sheet (5); a coil spring (12b) supporting the third valve body (8) toward the third valve sheet (5); and an operation rod (9) interposed between the first valve body (6) and the third valve body (8). |
