ABSTRACT:
A fluid scroll machine whose movable scroll is balanced with a simple construction to decrease the weight and cost of the machine. Counterweights are attached to the peripheral portion of the movable scroll, and the thickness of the engaged portion of the scroll is reduced at the part of the portion, which does not participate in the compression of gas in the machine, so that the scroll is balanced with regard to the rotation thereof. The counterweights are attached to the movable scroll to increase the total mass thereof to balance the scroll. The thickness of the part of the engaged portion of the scroll is reduced to decrease the total mass thereof to balance the scroll. Therefore, the counterweights can be made relatively small.
