Title:
Three-way solenoid valve
Document Type and Number:
Japanese Patent JP6333086
Kind Code:
B2
Abstract:
There is provided a very reliable three-way solenoid valve (1) that can reliably switch a refrigerant flow passage while ensuring a refrigerant flow rate even under a large-differential pressure environment without increasing the size of an electromagnetic coil and the like. A valve body (2) includes a conduction hole (2k) that communicates with a back pressure chamber (2eb)formed on a side of a second valve element (7) opposite to a second valve seat (4), a third valve seat (5) that is positioned between the conduction hole and a second outlet (2c), a third valve element (8) that is movably disposed so as to approach and be separated from the third valve seat, a coil spring (12b) that biases the third valve element toward the third valve seat, and actuating rods (9) that are interposed between a first valve element (6) and the third valve element.
