Embodiment Construction

[0015] The exemplary high pressure type scroll compressor shown in FIG. 1 may include a casing 10 forming a sealed inner space, and a main frame 20 and a subframe 30 fixed to upper and lower sides of the casing 10, respectively. A driving motor 40 may be disposed between the main frame 20 and the sub frame 30 to generate rotational force. The fixed scroll 50 may be fixed to the upper surface of the main frame 20 so as to communicate with the gas suction pipe SP. The orbiting scroll 60 having the involute wrap 62 performs an orbital motion through its mutual engagement with the wrap 52 of the fixed scroll 50 so as to form a plurality of pairs of compression chambers P. Referring to FIG. The Oldham ring 70 may be provided between the orbiting scroll 60 and the main frame 20 and surround the orbiting scroll 60 . A shaft hole 22 , a protrusion receiving groove 22 , and a counter pressure groove 23 may also be formed in the main frame 20 . The inlet 53 and the outlet 54 may be fo...

Abstract

A scroll compressor is provided. The scroll compressor includes a fixed scroll and an orbiting scroll, each with a wrap extending from a plate. The wrap or the plate may have different heights so as to prevent a gap from forming between the end of one of the wraps and the opposite plate. Accordingly, performance of the compressor may be enhanced even if manufacturing tolerances are not precisely controlled or the compressor operates for an extended period of time. Furthermore, frictional loss due to increased frictional area of an edge of the plate may be prevented, and refrigerant leakage due to separation between the wrap and the plate may be prevented.

Description

technical field [0001] The present invention relates to compressors, and more particularly to scroll compressors. Background technique [0002] A compressor converts mechanical energy into compression energy. Compressors may be classified into various types including, for example, reciprocating, scroll, centrifugal, and vane types. Scroll compressors can also be classified into low-pressure and high-pressure types based on whether suction gas or discharge gas is filled in their casings. In a scroll compressor, two scrolls perform relative orbital motion, and a pair of substantially symmetrical compression chambers are formed between the two scrolls. As the compression chambers successively move toward the center of the scroll, the volumes of the compression chambers decrease, thereby compressing refrigerant contained therein. The pair of compression chambers may include a high-pressure side compression chamber and a low-pressure side compression chamber. In some cases, r...
