Problems solved by technology

This may complicate the scroll compressor manufacturing process
[0010] Secondly, since the valve assembly is arranged between the low-pressure space and the high-pressure space, there is a large pressure difference between the low-pressure space and the high-pressure space
This may cause leakage of refrigerant in the high-pressure space into the low-pressure space, and the above-mentioned leakage may occur even when the scroll compressor performs a normal driving mode, thereby causing a decrease in the performance of the scroll compressor

Embodiment Construction

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] For brief description with reference to the drawings, the same or corresponding components will be given the same reference numerals, and descriptions thereof will not be repeated.

[0031] Hereinafter, a scroll compressor according to the present invention will be explained in more detail with reference to the accompanying drawings.

[0032] figure 1 is a longitudinal sectional view of a low-pressure scroll compressor according to the present invention.

[0033] As shown in the figure, a low-pressure type scroll compressor (hereinafter, referred to as a 'scroll compressor') according to the present invention includes: a hermetic container 1 having an inner space divided into suction as a low-pressure space; Space 11 and a discharge space 12 as a high-pressure space; a drive motor 2 installed in the suction space 11 of the airtight container 1 and generating a r...

Abstract

A scroll compressor is provided. The scroll compressor may include a valve and a valve spring accommodated in a housing as one module, and the housing may be directly coupled to a fixed scroll. This may simplify assembly processes of the scroll compressor. Further, a sealing recess that communicates with a middle pressure chamber may be formed at the housing, thereby forming a damping space between a high pressure space and a low pressure space. This may prevent lowering of performance of the scroll compressor due to leakage of refrigerant inside the high pressure space to the low pressure space in a normal driving mode.

Description

technical field [0001] The present invention relates to a scroll compressor, and more particularly, to a compressor capable of preventing vacuum by returning a part of the refrigerant discharged to the high-pressure space to the low-pressure space when the low-pressure space is evacuated during operation. Scroll compressor. Background technique [0002] A scroll compressor refers to a compression device formed with a pair of compression chambers, when the orbiting scroll is fixed to the inner space of a hermetic container at the fixed scroll and the orbiting scroll body of the orbiting scroll and the fixed scroll of the fixed scroll The compression chamber moves continuously between the fixed roll and the orbiting roll when the orbiting motion is performed in a state where the rolls are interlocked. [0003] Such a scroll compressor may have a higher compression ratio than other types of compressors, and may obtain stable torque since a suction process, a compression proces...
