That is, a rolling bearing (ring) is provided on the first drive side end plate 71a, and a pin member 15b is provided on the first support member 33. A driving force is transmitted from the driving side scroll member 70 to the driven side scroll member 90 by the pin ring mechanism 15, and both scroll members 70, 90 are rotated in the same direction at the same angular velocity.
　上記構成の両回転スクロール型圧縮機１は、以下のように動作する。
　モータ５によって駆動軸６が駆動側回転軸線ＣＬ１回りに回転させられると、駆動軸６に接続された第１駆動側軸部７ｃも回転し、これにより駆動側スクロール部材７０が駆動側回転軸線ＣＬ１回りに回転する。駆動側スクロール部材７０が回転すると、駆動力がピンリング機構１５を介して各サポート部材３３，３５から従動側スクロール部材９０へと伝達され、従動側スクロール部材９０が従動側回転軸線ＣＬ２回りに回転する。このとき、ピンリング機構１５のピン部材１５ｂが円形穴の内周面に対して接触しつつ移動することによって、両スクロール部材７０，９０が同じ方向に同一角速度で自転運動を行う。
　両スクロール部材７０，９０が自転旋回運動を行うと、ハウジング３の吸入口から吸い込まれた空気が両スクロール部材７０，９０の外周側から吸入され、両スクロール部材７０，９０によって形成された圧縮室に取り込まれる。そして、第１駆動側壁体７１ｂと第１従動側壁体９１ｂとによって形成された圧縮室と、第２駆動側壁体７２ｂと第２従動側壁体９２ｂとによって形成された圧縮室とが別々に圧縮される。それぞれの圧縮室は中心側に移動するにしたがって容積が減少し、これに伴い空気が圧縮される。第１駆動側壁体７１ｂと第１従動側壁体９１ｂとによって圧縮された空気は、従動側端板９０ａに形成された貫通孔９０ｈを通り、第２駆動側壁体７２ｂと第２従動側壁体９２ｂとによって圧縮された空気と合流し、合流後の空気が吐出ポート７２ｄを通り、ハウジング３の吐出口３ｄから外部へと吐出される。吐出された圧縮空気は、図示しない内燃機関へと導かれ、燃焼用空気として用いられる。 The double-rotating scroll compressor 1 having the above-described configuration operates as follows.
When the drive shaft 6 is rotated around the drive-side rotation axis CL1 by the motor 5, the first drive-side shaft portion 7c connected to the drive shaft 6 also rotates, thereby causing the drive-side scroll member 70 to move to the drive-side rotation axis CL1. Rotate around. When the driving scroll member 70 rotates, the driving force is transmitted from the support members 33 and 35 to the driven scroll member 90 via the pin ring mechanism 15, and the driven scroll member 90 rotates about the driven rotation axis CL2. To do. At this time, when the pin member 15b of the pin ring mechanism 15 moves while being in contact with the inner peripheral surface of the circular hole, both scroll members 70 and 90 rotate in the same direction at the same angular velocity.
When the scroll members 70 and 90 rotate and rotate, the air sucked from the suction port of the housing 3 is sucked from the outer peripheral sides of the scroll members 70 and 90 and is formed by the scroll members 70 and 90. Is taken in. The compression chamber formed by the first drive side wall 71b and the first driven side wall 91b and the compression chamber formed by the second drive side wall 72b and the second driven side wall 92b are separately compressed. The Each compression chamber decreases in volume as it moves toward the center, and air is compressed accordingly. The air compressed by the first drive side wall 71b and the first driven side wall 91b passes through the through-hole 90h formed in the driven side end plate 90a, and the second drive side wall 72b, the second driven side wall 92b, The compressed air is merged, and the merged air passes through the discharge port 72d and is discharged from the discharge port 3d of the housing 3 to the outside. The discharged compressed air is guided to an internal combustion engine (not shown) and used as combustion air.
