    Patent number: 5685161
    Abstract: A refrigerant recovery and recycling apparatus which transfers refrigerant from a first container to a second container. The refrigerant recovery and recycling apparatus comprises a compressor having a suction side and a discharge side. The suction side of the compressor is in fluid communication with the first container, and the discharge side is in fluid communication with the second container. A liquid/vapor sensor is connected to the first container to detect whether the refrigerant from the first container is in a liquid state or a vapor state. A heater is located between the first container and the suction side of the compressor. The heater is responsive to the liquid/vapor sensor to vaporize liquid refrigerant from the first container. A condenser having an inlet and an outlet is provided. The inlet of the condenser is in fluid communication with the discharge side of the compressor. A filter having an inlet and an outlet is also provided.
