REFRIGERATION CYCLE UNIT AND PUMP UNIT

摘要

PROBLEM TO BE SOLVED: To enhance lubrication at a sliding part of a pump unit without causing a refrigerant to be influenced by heat of a motor section in the pump unit conveying liquid refrigerant or the like of an air conditioner or the like. SOLUTION: A rotor 21 comprising a permanent magnet is provided in a sealed container 12, and a drive side magnet 10 for transmitting torque to the rotor is provided outside of the container so that a pump system 14 is rotated. The pump system 14 is constituted of a casing 15 and a pump rotor 16, and a passage for allowing a carrier liquid to flow to the shaft-sliding part is provided.
