本発明は、冷蔵庄のような冷凍／ステムに使用する回転

を説明する。Conventional 11JI1 configuration and its problems In general, in a rotary compressor, a large amount of lubricating oil is contained in the discharged waste discharged from the compression chamber of the compressor main body.
Feeding this as it is/into the stem not only causes a decrease in refrigerating capacity, but also may have an adverse effect on reliability. A conventional example will be explained below with reference to FIGS. 3 and 4.

た。FIG. 4 is a partial sectional view of section A in FIG. 3. 2 is a cylinder in the compression/compression mechanism, 3 is a bearing, 4 is a discharge muffler attached to the bearing 3 via a buff full 8, and has a discharge hole 6 in the direction of the axis O. 5 is a discharge pipe through which the gas discharged from the discharge muffler 4 is discharged to a refrigeration/stem (for example, a cold H. pressure refrigeration/stem). When the rotary compressor is operated, the discharge gas containing a large amount of lubricating oil from the compression chamber 7 enters the discharge muffler 4, is discharged from the discharge hole 6 in the direction of arrow P, and exits from the discharge pipe 5/stem. . Therefore, there were problems such as a large amount of oil surrounding the system, a decrease in refrigeration ability, and a decrease in IJ reliability.
発明の目的

This prevents oil from entering.

8 is a compression chamber, and 8 is a full bath, and these configurations are the same as the conventional one. 6' is a discharge hole provided in the discharge muffler 4 in its radial direction (direction of arrow P'), and the position of this discharge hole 6' in the discharge muffler 4 is a feature of the present invention. The compressed discharge gas is discharged from the discharge hole 6' in the radial direction of the discharge muffler 4 and collides with the wall of the sealed container 1, and oil, which has a higher quality than the refrigerant, comes out. The discharged gas, which is oil-separated and has a low lubricating oil content, is discharged from the discharge pipe 5 into the system.

It is H. Note that FIG. 2 is a sectional view of a main part of a discharge muffler showing another example of the present invention, in which the discharge holes e of the discharge muffler 4 are
By providing the flange back 6a' in the discharge muffler 4, the oil that is to be discharged to the outside from the discharge muffler 4 is guided inside the discharge muffler 4 along the flange back 6a', thereby further enhancing the oil separation effect.
