ABSTRACT:
Both ends of a circling scroll are supported by a pin crank and the eccentric shaft of the circling scroll, thus assuring a stable circling or oscillating motion of the scroll. This in turn allows the scroll tooth length to be elongated, leading to an increase in the capacity of the fluid machine. Because the eccentric shaft and the pin crank are fitted into the center boss, the pin crank can work as a shaft that supports the left end of the circling scroll. The provision of the boss allows a radial load acting on the scroll tooth to be borne at the load position, thus shortening the shaft and reducing the bearing. Because the pin crank can be mounted to the boss, a two-block parallel arrangement and two-stage arrangement can be implemented easily. Further, the construction in which the pin crank is used as a left-end supporting bearing contributes to reducing the manufacturing cost of the apparatus.
