Abstract

PURPOSE:To adjust the suction quantity of fluid according to the demand by varying the relative phase angle by turning one between a fixed scroll and movable scroll around the turning shaft of the movable scroll. CONSTITUTION:A fixed scroll 2 is turned by the angle alpha in the counterclockwise direction around the turning shaft of a movable scroll 1 in comparison with the conventional, and the phase difference between the movable scroll 1 and the fixed scroll 2 is 180 deg.-alpha. The gap (t), in other words, the thickness of the swirl body 2 of the fixed scroll can be arbitrarily varied by adjusting the pulling quantity of the shifting teeth 3 by a position adjustor 4. Therefore, the fluid suction quantity can be adjusted according to the demand, and the dynamic characteristic of a fluid machinery can be improved.
