Abstract

PURPOSE: To obviate a mechanism for fluctuation movement which has conventionally been reguired and permit reduction of discharge pulsation by using a plurality of scroll bodies and guiding always fluctuation scroll by means of a fixed scroll.
CONSTITUTION: When a pulley 10 is revolved through a V-belt by a motor, a crank shaft 7 revolves and a fluctuation scroll 2 starts fluctuation motion. In this case, a plurality of scroll pairs are formed, and as the fluctuation scroll 2 is inserted freely, rotatably onto the crank shaft 7, the fluctuation scroll 2 tends to alter the situation for the space, but due to the continual contact with the fixed scroll 1, the fluctuation scroll 2 is guided by the fixed scroll 1 and starts fluctuation movement. Thus, special guiding mechanism is obviated, and discharge pulsation can be reduced in size, compared with the conventional ones which use one scroll element only.
