A scroll type system in which high-pressure air is drawn into a closed space formed by the orbiting scroll, gradually reducing its volume as the orbiting scroll revolves, moving toward the center, compressing it, and discharging the high-pressure air to the outside from the discharge port. Compressors are known.

二段圧縮等を構成する上でも極めて有利である。Such a scroll fluid machine is a so-called face-to-face scroll fluid machine (for example, Japanese Patent Laid-Open No. 50-325
No. 12) and a pair of fixed scrolls having wraps that can be fitted with the wraps are sandwiched between both sides of one orbiting scroll having wraps formed on both sides in the axial direction, respectively, and the revolution of the orbiting scroll of - By movement, a predetermined expansion, compression, or pumping movement is performed on each of the two sides,
So-called twin scroll fluid machine
No. 2081) has been proposed, but the latter is capable of performing compression movements on both sides of the orbiting scroll, and as a result, from the viewpoint of power/compression efficiency and the need for miniaturization, it is possible to perform a two-stage It is also extremely advantageous in configuring compression and the like.

と鏡面間を実質的に面接触させながら圧縮運動を生ぜし
める為に、対面するスクロール同士の平行度維持とスラ
スト調整を精度よく行なう必要がある。``Problems to be Solved by the Invention'' Now, a scroll fluid machine has a wrap end surface that slides relative to a mirror surface (sliding surface) of a mating scroll via oil or other sealing material. In order to generate compressive motion while substantially making surface contact between the scrolls and the mirror surfaces, it is necessary to maintain the parallelism of the facing scrolls and to precisely adjust the thrust.

１２０°づつ角度変位させた位置に夫々スラスト調整手
段を設け、前記両スクロールの平行度維持とスラスト調
整を行なっている。For this reason, in any of the scroll fluid machines mentioned above, each thrust is adjusted to a position angularly displaced by 120 degrees, for example, on the wall surface of the fixed scroll located on the outer peripheral side of the wrap forming space (compression space) (facing the helical scroll). Means is provided to maintain the parallelism and adjust the thrust of both scrolls.

印加されてしまう為にそのスラスト調整が極めて困難と
なる。However, in the twin-scroll fluid machine, since a pair of fixed scrolls are arranged on both sides of a helical scroll, in other words, even though the helical scrolls are shared, there is a thrust between the orbiting scroll and the fixed scroll, respectively. In order to adjust the thrust independently of the fixed scroll on the other side by providing an adjustment means, the error of the fixed scroll on the other side is applied in addition to the processing and assembly error of the fixed scroll on the negative side, making the thrust adjustment extremely difficult. It becomes difficult.

As shown in No. 81, by using a main shaft for revolution movement inserted through the center axis of each scroll, and a plurality of eccentric rotation shafts for regulating rotation provided on the outer circumferential side of the scroll,
By integrally assembling each of the scrolls via bearings, etc., the parallelism between the scrolls and the occurrence of thrust errors are eliminated as much as possible. However, such a configuration significantly reduces the assembly and processing accuracy of each scroll. Unless the precision is high, the desired purpose cannot be achieved.Moreover, the three scrolls must be integrally supported by the main shaft and multiple rotating shafts (supported at multiple points). It cannot tolerate runout, and even if it can, it has the disadvantage that the shaft power increases by several orders of magnitude.

It is an object of the present invention to provide a scroll fluid machine that can absorb the error and maintain the sealing performance between the wrap end surface and the opposing mirror surface even when the scroll fluid machine has a desired compression or expansion efficiency.
