なシ機械損失上昇、焼きつけなどの問題が生じる。Problems to be Solved by the Invention In conventional compressors, the electric motor of the driving part and the compression part are provided separately in the axial direction, so it is difficult to downsize the compressor. If a driving part is installed around the outer circumference of the compressor to reduce its size and rotate it at a higher speed to increase its capacity, a large amount of lubricating oil will be carried out from the compressor body to the outside (during the refrigerant cycle), and the inside of the compressor will increase. The amount of lubricant is below the appropriate level. Therefore, problems such as poor lubrication of bearings, shafts, etc., increased mechanical loss, and seizure occur.

め部、油溝を通って７・ウジング内へ吐出される。The discharged refrigerant is conveyed from the refrigerant discharge pipe to the refrigerant cycle. Also, the lubricating oil is supplied from the lower part of the housing to the first piston part by the action of the oil supply pump from the oil groove of the rotating lower bearing.
The oil is discharged through the oil reservoir, through the oil flow passage, through the second oil reservoir of the upper bearing, and the oil groove into the housing 7.
吐出された冷媒中の潤滑油および油溝から吐出された潤
滑油は、遠心力によりハウジングの内壁へ飛ばされる。The lubricating oil in the discharged refrigerant and the lubricating oil discharged from the oil groove are blown toward the inner wall of the housing by centrifugal force.

へ持ち出す量は少なくなる。In addition, the lubricating oil (refrigerating machine oil) accumulated in the lower part of the housing 18 passes through the lower bearing oil groove 15 by the action of the oil supply pump due to the rotation of the lower bearing 14, and accumulates in the first oil reservoir 4, where it is collected. The section seals the surfaces of the piston section 2 and the lower bearing 14 by centrifugal force. The remaining lubricating oil flows through the oil flow passage 5 to the second oil reservoir 10, and here, similarly, some lubricating oil flows into the upper bearing 12.
and seal the surface of the piston part 2. As the upper bearing 12 rotates, other lubricating oil is sucked upward through the upper bearing oil groove 11 by the oil supply pump action and is discharged into the internal space of the housing 18. The lubricating oil mixed with the refrigerant discharged from the discharge valve 13 and the lubricating oil discharged from the upper bearing oil groove are
2 is rotating, the inner wall of the housing 18 is blown off by centrifugal force. The lubricating oil on the inner wall of the housing 18 flows along the wall surface and collects at the lower part of the housing 18. Here, since the discharge port 19 of the refrigerant discharge pipe 20 is provided in the same direction as the rotation direction (arrow in Fig. 3), lubrication @ (oil from the oil groove in the refrigerant)
The amount of refrigerant directly carried out from the refrigerant discharge pipe 20 into the refrigerant cycle (not shown) is reduced.
したがって、ハウジング１８下部には常に適正量の潤滑
油が保持でき、潤滑油の減少にともなう機械損失の上昇
・跪きつけ等の問題もない。Therefore, an appropriate amount of lubricating oil can always be held in the lower part of the housing 18, and there are no problems such as increased mechanical loss or kneeling caused by a decrease in lubricating oil.
