PROBLEM TO BE SOLVED: To provide a refrigerant pump of a thin shape usable in a unit of a stringent height limitation. SOLUTION: The refrigerant pump is provided with a closed container having an upper container 2 and a lower container 4 joined together, a pump mechanism section 6 received in the closed container and an electric motor having a stator 8 and a rotor 10 disposed adjacent to each other in the pump mechanism section 6. An annular concavity 4a is formed in an outside of the lower container 4 for fixing the stator 8 and the rotor 10 is opposed to the stator 8 and is disposed radially outward of the stator 8 in the lower container 4. The pump mechanism section 6 is received in a space 16 formed between a bearing end plate 12 rotating together with the rotor 10 and a cylinder shaft 14 supporting the bearing end plate 12 fixed to the upper container 2. The pump mechanism section 6 is driven in association with rotation of the rotor 10 and the bearing end plate 12. COPYRIGHT: (C)2006,JPO&NCIPI
