ABSTRACT:
The invention provides a relief valve for discharging refrigerant in a receiver drier equipped to an air conditioner of a car. A receiver drier1of an air conditioner of a car has an inlet path44and an outlet path46of refrigerant formed to a body10, and retains refrigerant. A valve chamber184is formed to the end of the body10, which communicates with the atmosphere via a path182and a path184. A plunger170of a solenoid valve100is regularly in contact with a valve seat180. When power is supplied to the coil120based on a signal from a sensor, an attractor140separates the plunger170from the valve seat180and allows the refrigerant to be discharged to the atmosphere.
