Problems solved by technology

In particular, if the pipe is installed inside the chamber, the size of the chamber should be increased to accommodate the pipe therein, making the size of the cylinder undesirably bulky
[0011] Therefore, the space utilization and output of the compressor are reduced

Embodiment Construction

[0032] The following will refer to the attached Figures 1 to 7 An example of a hermetic compressor having a discharge pulsation reducing member installed therein according to the present invention will be specifically described.

[0033] According to the present invention, if figure 1 and 2 As shown, a hermetic compressor having a discharge pulsation reducing part installed therein is installed in a machine compartment of a refrigerator, and is connected to a condenser (not shown) to compress gaseous refrigerant to a high pressure and supply the compressed refrigerant to To the condenser, the hermetic compressor generally includes a casing 1 ; a cylinder 100 disposed in the casing 1 ; and a discharge muffler 200 disposed on an upper portion of the cylinder 100 to reduce a pulsation component of discharged refrigerant.

[0034] The discharge muffler 200 has a first chamber 210 and a divided second chamber 220 , and the first chamber 210 and the second chamber 220 are connect...

Abstract

The present invention relates to a hermetically-sealed compressor in which a member for reducing discharge pulsations is installed, and which includes: a case; a cylinder block disposed in the case; a discharge muffler in which a first chamber and a second chamber are formed so as to be spaced apart from each other in the upper portion of the cylinder block, in order to reduce the pulsations of a refrigerant which is discharged, wherein a connection passage is formed on the inner side between the first chamber and the second chamber; and a pulsation-reducing member inserted in and fixed to the connection passage, wherein a pulsation-reducing passage is formed on the circumferential surface thereof.

Description

technical field [0001] The present invention relates to a compressor, more particularly to a hermetic compressor on which a discharge pulsation reducing component is installed for controlling the pulsation component of working fluid and reducing the vibration and noise generated by the compressor during the refrigeration cycle. Background technique [0002] In general, a refrigeration cycle is a process in which refrigerant gas having high temperature and high pressure compressed by a compressor is liquefied by a condenser, and then vaporized in an evaporator through an expansion valve, thereby cooling using the heat of vaporization of the refrigerant. [0003] In the refrigeration cycle, a compressor is a device used to compress vaporized refrigerant from an evaporator into high temperature and high pressure, and in the evaporator, the liquefied refrigerant is vaporized and cooled by removing surrounding heat. [0004] However, the pulsation component generated when the gas...
