There is disclosed a pressure control valve comprising: a valve body (10A) provided successively with, mentioning from the upstream side in the flowing direction of refrigerant, a refrigerant inflow port (11), a refrigerant introduction chamber (14), a valve seat (13) with which a rod-like valve (15) is retractably contacted, and a refrigerant outflow port (12); and a temperature-sensitive/pressure-responsive element (20) which is provided with a temperature sensitive chamber (25) for sensing the temperature of the refrigerant that has been introduced into the refrigerant introduction chamber (14) and is designed to drive the valve (15) in opening or closing direction in response to fluctuations of the inner pressure of the temperature sensitive chamber (25). The temperature-sensitive/pressure-responsive element (20) is integrally attached to the valve body (10A). |
