ROTARY SCROLL COMPRESSOR

PURPOSE:To surely seal between meshing laps by rotatably providing the bearing part of a second scroll around an axis different from respective rotation axes of a first and a second scrolls, and constituting the axis of the second scroll so as to be movable against the axis of the first scroll. CONSTITUTION:A motor element 2 and a scroll compressor element 3 are housed in series in a closed vessel 1. The scroll compressor element 3 is provided with a first scroll 4 of driving side which is provided with a spiral lap 4a and connected to the motor element 2 and rotated around the common axis A with the motor element 2, and a second scroll 5 of driven side which is provided with an axis B eccentric to the axis A by an eccentric quantity of (e) and a lap 5a meshing with the lap 4a. A bearing part 7 supporting the second scroll 5 is rotatably provided centering around an axis C different from the axis A and the axis B, and the axis B is let movable against the axis A. Hereby, sealing between the mutually meshing laps 4a, 5a is surely performed.
