Abstract
A first fixed scroll has a first fixed wrap, and a first orbiting scroll has a first orbiting wrap. The first orbiting scroll is rotatably mounted to an eccentric portion of a driving shaft. The first fixed wrap is engaged with the first orbiting wrap to form a first compression chamber in which pressure is changed towards the center of the first orbiting scroll. A second fixed scroll has a second fixed wrap and a second orbiting scroll has a second orbiting wrap which is engaged with the second fixed wrap. The first orbiting scroll is connected to the second orbiting scroll by a pin inserted a partition wall between the first and second orbiting scrolls, thereby rotating the first orbiting scroll together with the second orbiting scroll when the first orbiting scroll is driven by the driving shaft via the eccentric portion.
