〔発明の目的〕
（産業上の利用分野）
この発明は、スクロールコンプレッサの主軸の給油方法
に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a method for lubricating the main shaft of a scroll compressor.
（従来の技術）

軸が回転を初めると遠心ポンプ内の潤滑油が遠心力によ
り外周方向へ移動しようとするため上部へ給油される。(Prior Art) Conventional scroll compressors have been oiled using centrifugal pumps that use centrifugal force inside the main shaft to supply oil. When the main shaft starts rotating, the lubricating oil inside the centrifugal pump tends to move toward the outer circumference due to centrifugal force, so it is supplied to the upper part.

このスクロールコンプレッサによれば、主軸の回転数が
増加するにつれて給油量が多くなるため、高速回転時に
は必要以上の潤滑油かり６含油され。(Problems to be Solved by the Invention) According to this scroll compressor, the amount of oil supplied increases as the rotational speed of the main shaft increases, so that more lubricating oil than necessary is contained during high-speed rotation.
画滑油が吐出ガスに混入して圧縮機外に出てしまうとい
う問題点があった。There was a problem in that the oil got mixed into the discharged gas and came out of the compressor.

とを目的とする。It is an object of the present invention to provide a scroll compressor having a centrifugal pump capable of solving the above-mentioned problems of the conventional compressor and supplying an appropriate amount of lubricating oil depending on the number of rotations.
（問題を解決するための手段）

いる。(Means for Solving the Problem) In order to achieve this object, the present invention has a basic structure. That is, the scroll compressor according to the present invention has a valve body in the transverse pipe that crosses the centrifugal pump of the main shaft. An elastic body is installed to restrict the movement.
（作用）

。(Function) When the scroll compressor is driven and the main shaft is rotated, the valve body in the cross pipe receives centrifugal force. As the rotational speed of the main shaft increases, the valve body balances the elastic force of the elastic body and stops in a direction that blocks the flow path of the centrifugal pump.

An Oldham ring 6 is provided between the orbiting scroll 4 and the frame 2 to mesh with the orbiting scroll 4 and the frame 2 to prevent rotation of the orbiting scroll 4 during the orbiting motion. A suction hole is provided on the side surface of the frame 2, and a suction pipe 7 is attached thereto.

As the rotor 8 rotates, the main shaft 3 starts rotating, and the orbiting scroll 4 starts an orbiting motion. The refrigerant that enters the compression mechanism section through the suction pipe 7 is compressed and discharged into the closed container 1 through the central opening 5C of the fixed scroll 5, and is then discharged into the closed container 1 through the discharge pipe 10.
Get out of the airtight container. Lubricating oil stored at the bottom of the closed container 1 is pumped up by a centrifugal pump 3a within the main shaft 2, and lubricates the sliding surfaces of the compression mechanism.

a pumps up lubricating oil. As the rotation speed of the main shaft 3 increases, the centrifugal force applied to the valve body 3C increases, and the centrifugal force applied to the centrifugal pump 3a increases.
move in the direction of narrowing the flow path. This amount of movement can be set to an arbitrary amount depending on the rotational speed l by changing the elastic force of the spring. In this way, the cross-sectional area of the centrifugal pump's flow path can be changed according to the rotational speed, so even if the rotational speed increases, the monthly supply of lubricating oil does not increase significantly, and the lubricating oil does not get mixed into the discharged gas. The lubricating oil coming out of the compressor will deteriorate.
