[0053] Figures 5A-5B Shows the steps of forming the first involute and the second involute for the orbiting scroll of the scroll compressor according to the first preferred embodiment of the present invention. Referring to this figure, steps of forming the first involute 101 and the second involute 102 are explained.

[0054] In order to form the moving scroll 100 (see Figure 7 ), need two involutes, namely the first involute 101 and the second involute 102.

[0055] like Figure 5A As shown, to form the first involute 101, an imaginary base circle 50 of radius 'a' is formed at the center of the X-axis and the Y-outer axis. Then, take a point on the circumference of the base circle 50 whose starting angle is 'α' relative to the X-axis as the starting point, and draw an inner involute 101a. like Figure 5A As shown, in order to form the thickness 't1' of the orbiting scroll 100 of the first involute 101, take a point on the circumference of the base circle 50 with a star...

[0081] Figures 9A-9B Shows the steps of forming the fixed scroll and the movable scroll according to the second preferred embodiment of the present invention. Figure 10 Indicates the cooperation between the movable scroll and the fixed scroll formed according to the second preferred embodiment of the present invention. Referring to this figure, the structures of the movable scroll 400 and the fixed scroll 300 of the second embodiment of the present invention will be described in detail.

[0082] refer to Figure 9A , to form the orbiting scroll 400, an imaginary base circle 410 with a radius 'a' is formed at the center of the X-axis and the Y-outer axis. Then, take a point on the circumference of the base circle 410 relative to the starting angle 'α' of the X-axis as the starting point to form an inner involute 411 . like Figure 9A As shown, in order to form the thickness of the orbiting scroll 400, a point on the circumference of the base circle 410 relative to the sta...

[0089] Figures 11A-11B Shows the steps of forming the fixed scroll and the movable scroll according to the third preferred embodiment of the present invention. Figure 12 It shows the cooperation state between the movable scroll and the fixed scroll formed according to the third preferred embodiment of the present invention. Referring to this figure, the structures of the movable scroll 600 and the fixed scroll 500 of the third embodiment of the present invention will be described in detail.

[0090] and Figure 9A , 9B Similar to the description above, in order to form the orbiting scroll 600, a point on the circumference of a base circle 610 with a radius 'a' relative to the starting angle 'β1' of the X-axis is taken as the starting point to form an inner involute 611. In order to form the thickness of the orbiting scroll 600, take a point on the circumference of the base circle 610 relative to the starting angle '-β1' of the X-axis as the starting point, and make an out...

Abstract

Scroll compressor including wraps of involute curves on opposite surfaces of an orbiting scroll and a fixed scroll engaged to each other, to form a compression chamber as the orbiting scroll orbits with respect to the fixed scroll, wherein each of the wraps on opposite surfaces of the orbiting scroll and the fixed scroll is formed from two or more than involute curves each having a base circle and a point of starting different from each other, thereby permitting to secure a larger compression space for a same sized scroll compressor while a reliability of the scroll compressor is not made poor, to reduce a centrifugal force and noise occurred at the orbiting scroll, and improving a stability of the orbiting scroll.

Description

technical field [0001] The present invention relates to scroll compressors, and more particularly, to the structure of each scroll for compressing refrigerant in a scroll compressor, wherein a movable scroll orbits with respect to a stationary scroll. Background technique [0002] Generally, scroll compressors are mainly used in room air conditioners or car air conditioners due to their low noise, small size, and light weight. Among them, a pair of opposing scrolls constitutes a compression chamber in which refrigerant is compressed. figure 1 A sectional view showing a prior art scroll compressor, with reference to which the prior art scroll compressor will be explained. [0003] refer to figure 1 , here a closed housing of the main body 1, having connected thereto an inlet pipe 11 and an outlet pipe 15 for sucking in and discharging refrigerant, respectively. There is a fixed scroll 8 on the upper part of the main body 1, and an involute scroll 8a protruding downward fro...
