PROBLEM TO BE SOLVED: To improve airtightness of a compression chamber by a simple configuration in a scroll-type compressor in which a revolving shaft is arranged to pass through a movable scroll.SOLUTION: A curvature factor at a segment of an extremity end curve Ic drawn by a high-stage side movable tooth 11c contacted with a high-stage side stator side tooth 13b when a movable scroll 11 is displaced to a position where it forms a high-stage side compression chamber VH of minimum volume is formed to be smaller than a curvature factor of an arc in which the maximum value Ti of a thickness size T in a radial direction of the high-stage side movable tooth 11c is applied as a diameter. With this arrangement as above, a seal length L at a clearance between the high-stage side movable tooth 11c and the high-stage side stator tooth 13b is expanded and an air-tightness in the high-stage side compression chamber VH is improved. |
