Benefits of technology

The technical effect of the patent text is that the scroll compressor is designed to prevent the horizontal scroll from tilting due to the force of gas.

Problems solved by technology

However, on the contrary, the operating point to which a repulsive force of refrigerant is applied and the operating point to which a reaction force for cancelling out the repulsive force is applied are separated from each other in an axial direction, thereby causing a problem of increasing vibration or noise while the orbiting scroll is tilted during the operational process.

Embodiment Construction

[0032]Hereinafter, a scroll compressor according to the present disclosure will be described in detail based on an embodiment illustrated in the accompanying drawings.

[0033]Referring to FIG. 3, a scroll compressor according to the present embodiment has a cylindrically shaped casing 110, and an upper shell 112 and a lower shell 114 for covering an upper portion and a lower portion of the casing, respectively. The upper shell and lower shell may be bonded to the casing to form one confined space together with the casing.

[0034]A discharge pipe 116 may be provided at an upper portion of the upper shell 112. The discharge pipe 116 corresponds to a path through which compressed refrigerant is discharged to the outside, and an oil separator (not shown) for separating oil mixed with the discharged refrigerant may be connected to the discharge pipe 116. Furthermore, a suction pipe 118 is provided at a lateral surface of the casing 110. As a path through which refrigerant to be compressed fl...

Abstract

The present disclosure relates to a scroll compressor. According to the present disclosure, in a shaft penetration scroll compressor in which an eccentric portion of the rotation shaft is overlapped with a orbiting wrap of the orbiting scroll in a radial direction, a back pressure chamber formed at a rear surface of the orbiting scroll may be eccentrically formed from the circular center around a discharge port to correspond to the eccentric discharge port, thereby effectively preventing tilting of the orbiting scroll due to the eccentricity of a gas force generated while the discharge port is eccentrically formed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to Korean Application No. 10-2011-0098587, filed in Korea on Sep. 28, 2011 and Korean Application No. 10-2011-0098597, filed in Korea on Sep. 28, 2011, which is herein expressly incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]A scroll compressor is disclosed herein.[0004]2. Description of the Related Art[0005]Scroll compressor may include a fixed scroll having a fixed wrap and a orbiting scroll having a orbiting wrap. The scroll compressor provides a method of inhaling and compressing refrigerant through a continuous volume change of the compression chamber formed between the fixed wrap and the orbiting wrap while the orbiting scroll performs a circulating movement on the fixed scroll.[0006]Furthermore, the scroll compressor continuously performs inhalation, compression and discharge, and thus has excellent characteristics in the aspect of vi...
