Abstract
A scroll type fluid machinery includes first and second fluid volume changing mechanisms. The first fluid volume changing mechanism includes a first stationary scroll and a first orbiting scroll, and the first orbiting scroll is associated with the first stationary scroll so that the first orbiting scroll is able to orbit with respect to the first stationary scroll. The second fluid volume changing mechanism includes a second stationary scroll and a second orbiting scroll, and the second orbiting scroll is associated with the second stationary scroll so that the second orbiting scroll is able to orbit with respect to the second stationary scroll. The scroll type fluid machinery further includes a plurality of orbiting units. Each of the orbiting units includes a rotating member that is able to rotate relative to the first and second stationary scrolls, and a thrust-canceling shaft connected to the first orbiting scroll and to the second orbiting scroll. The thrust-canceling shaft is eccentrically and rotatably supported in the rotating member, and the orbiting units are arranged to form one or more parallelogram linkages for preventing the first and second orbiting scrolls from sel…
