Abstract
After the tooth portionof the stationary scrolland the tooth portionof the revolving scrollhave contacted each other on one contact facein the central portion of the scroll (shown in FIG.A), when this contact faceis shifted to two sliding contact portions, the operating chamber V is formed between the two sliding contact portions(shown in FIG.B), and the refrigerant introducing portis open to the region on the contact face. Accordingly, the operating chamber can be instantaneously changed over while the sealing property is ensured. Due to the above structure, the sealing property for suppressing leakage from the high pressure side at the time of the expansion mode can be compatible with the smoothing property for smoothing a change-over of the scroll operating chamber successively formed.
