Problems solved by technology

[0016] However, in conventional scroll compressors, the eccentric bushing 12 that rotates at the initial stage of compressor startup can be restored to the normal position only when the compressor is operated normally due to the centrifugal force of the continuous rotary motion of the orbiting scroll 7 being greater than the gas pressure. , so it takes a long time, and there is a continuous leakage of refrigerant gas during the time, which reduces the compression efficiency of recompression and the performance of the machine

Embodiment Construction

[0043] Hereinafter, the structure of the present invention will be described in detail with reference to the drawings and examples.

[0044] Figure 4 It is an exploded perspective view of an eccentric bushing according to an embodiment of the present invention.

[0045]Generally, the eccentric bushing 12 is provided with a crankpin coupling hole 12b and a brake coupling hole 12a, and is rotatably coupled to the crankpin coupling hole 12b with the crankpin 10 arranged on the upper end surface of the crankshaft 6, one side of the crankpin 10 The upper part is formed with a brake hook surface 10a in a vertical section, and when the brake 23 is inserted into the brake coupling hole 12a of the eccentric bush 12 to rotate the eccentric bush 12, the brake 23 contacts the brake hook surface 10a to limit the movement of the eccentric bush 12. amount of rotation.

[0046] In the eccentric bushing brake of the scroll compressor, there is a device that compresses the eccentric bushing ...

Abstract

The invention discloses an eccentric liner stop device of vortex-type compressor, which consists of cylinder-shape hollow stopper host and incision part at the vertical direction of stopper host. When the eccentric force of rotary vortex disk is less than the gas pressure in the compression chamber and the eccentric liner rotates toward radius direction, it will apply the elastic force to the eccentric liner of inversion direction, which shortens the normal position restoring time of eccentric liner. Hence, the device reduces the coolant leakage of rotary eccentric liner, which improves the compression efficiency and property and reduces the preparing cost.

Description

technical field [0001] The present invention relates to an eccentric bushing of a scroll compressor, and particularly relates to a scroll compressor for a rotary compressor which shortens the normal position recovery time of the eccentric bushing, thereby cutting off the leakage of refrigerant gas caused by the rotation of the eccentric bushing in advance Eccentric bush brake. Background technique [0002] Generally, scroll compressors such as figure 1 As shown, the main frame 2 and the auxiliary frame 3 including the inner upper and lower parts of the shell 1 are pressed into the inside of the shell 1 by the stator 4 between the main frame 2 and the auxiliary frame 3, and the inside of the stator 4 is provided with The rotor 5 is rotated by the input power. The central part of the rotor 5 is inserted and fixed with a vertical crankshaft 6 that rotates together with the rotor 5. The upper and lower parts of the crankshaft 6 are rotatable by the main frame 2 and the auxiliar...
