| 摘要 | PURPOSE: To enable a suitable amount of refrigerant to be filled by providing a refrigerant passageway communicating to a hollow boring blade for opening a hole on one end side of a refrigerant can, a refrigerant passageway communicating to a hollow boring blade for opening a hole on the other end side thereof and a refrigerant liquid level display part communicating to one of the refrigerant passageways. CONSTITUTION: A refrigerant can 1 is inserted through the opening 2a of the main body of a filling apparatus 2, the sealed part 5 of said refrigerant can 1 being faced down. The refrigerant can 1 is turned in a state that the sealed part 5 abuts against a can opening part 6, and the sealed part 5 is thrusted into the can opening part 6. When the sealed part 5 is opened, a capillary 8 is pushed up by a resilient member 9. After the refrigerant can 1 is mounted in the main body of the filling apparatus 2, the knob 26 of a can opening part 21 is turned to open a hole on the side-wall of the refrigerant can 1 with the aid of a hollow boring blade 22. When an opening and closing valve 13 is opened by turning a knob 14, the refrigerant in the refrigerant can 1 flows into a liquid level display part 4, and the liquid level of the refrigerant is displayed. An outlet part 19 is connected to an air-conditioning apparatus and the like into which the refrigerant in the refrigerant can 1 is filled by turning a valve 20. Since the liquid level of the refrigerant is displayed, a suitable amount of the refrigerant can be filled. COPYRIGHT: (C)1990,JPO&Japio |
