Abstract

In a double-wrap scroll fluid machine, the first orbiting scroll provides the first orbiting wrap (11) which engages with the first stationary wrap (13) of the first stationary scroll. The first orbiting scroll is revolved by the first driving shaft (5). The second orbiting scroll provides the second orbiting wrap (11) which engages with the second stationary wrap (13) of the second stationary scroll. The second orbiting scroll is revolved by the second driving shaft (5). The inner end of the first driving shaft is connected to the inner end of the second driving shaft to allow them to rotate together by an endless belt (23). The endless belt (23) can easily be detached by spacing the two driving shafts (5).
