ABSTRACT:
After the tooth portion102bof the stationary scroll102and the tooth portion103bof the revolving scroll103have contacted each other on one contact face121in the central portion of the scroll (shown in FIG.5A), when this contact face121is shifted to two sliding contact portions122, 123, the operating chamber V is formed between the two sliding contact portions122, 123(shown in FIG.5B), and the refrigerant introducing port105ais open to the region on the contact face121. 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.
