Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerant cylinder which uses a refill prohibiting container in which a safety valve is hard to break when being handled.SOLUTION: A refrigerant cylinder which is for filling a refrigerant has an NRC container, a refrigerant discharge path for discharging the refrigerant to the outside, and a valve for opening/closing the refrigerant discharge path. The NRC container includes a grip around the refrigerant discharge path. Out of the NRC container and the refrigerant discharge path, a spring type safety valve is provided only in the refrigerant discharge path. In the valve, a float is provided on the refrigerant discharge path side. When the valve is closed, the float is pressed down, and the refrigerant discharge path is closed, and when the valve is opened, the float is pushed up by an internal pressure of the NRC container in which the refrigerant is filled, and the refrigerant discharge path is opened. Also, when the refrigerant is tried to be re-filled in the NRC container, the float automatically comes down, the refrigerant discharge passage is closed, and the refilling of the refrigerant is prevented.SELECTED DRAWING: Figure 1
