触面積が確保できず、固定強度および気密信頼性に問題
があった。The oil separator shown in the prior art 1 (FIG. 6) configured as described above has a hole which is inclined in a circumferential direction from a direction perpendicular to the side surface 1a of the main body container 1. However, it was difficult to manufacture a hole at a position offset from the center line of the main container 1 in terms of manufacturing. Also, Side 1
By making a hole in the oblique direction with respect to a, it was more difficult to make this hole into a burring shape. Therefore, a contact area for fixing the main body container 1 and the inlet pipe 2 at the perforated portion, for example, a contact area for brazing at the time of brazing cannot be secured, and there is a problem in fixing strength and airtight reliability.

The accuracy of the blowing direction at the time of fixing the inlet pipe 2 is deteriorated. As a result, if the blowing direction shifts, the pressure loss inside the oil separator increases, and the oil separation efficiency of the oil separator decreases, which has the adverse effect. Also,
A process of making a hole in the side surface 1a of the main body container 1 is added, and the cost is extra.

保するのが困難となる。Furthermore, a pressure vessel-shaped oil separator composed of three parts as shown in the prior art 3 (FIG. 8) is generally more expensive than one composed of one part. When the outlet 3a of the outlet pipe 3 is higher than the inlet 2a of the inlet pipe 2, a short cycle occurs in which the blown refrigerant flow leaves the outlet 3a as it is before turning sufficiently. , Leading to a decrease in oil separation efficiency. Further, when the diameter of the outlet pipe 3 is smaller than the diameter of the main body container 1, the contraction pressure loss due to the rapid contraction of the cooling channel is large. In order to increase the centrifugal acceleration a (a = v 2 / r) required to separate the oil in the gas refrigerant flowing at the flow velocity v, it is necessary to reduce the diameter r of the main container l. However, when the diameter is reduced, it becomes difficult to secure a clearance between the components such as the main body container 1, the inlet pipe 2, and the outlet pipe 3.

な入口管の吹出口方向を精度良く決めることができる。Further, since the diameter of the suction port of the outlet pipe is enlarged,
It is possible to reduce the contraction pressure loss when the refrigerant flow path is rapidly reduced to the outlet pipe through the main body container. Further, since the inlet pipe is fixed in contact with the outlet pipe in the main body container, the direction of the outlet of the inlet pipe which is dominant in the change of the oil separation efficiency can be determined with high accuracy. Further, since the inlet pipe is fixed in contact with the inner periphery of the main body container, the direction of the outlet of the inlet pipe which is dominant in the change of the oil separation efficiency can be determined with high accuracy.
