Problems solved by technology

However, since there is no device or structure for buffering the disturbance in the conventional suction muffler 10, changes in the amount and flow velocity of the refrigerant at the suction port 12 directly lead to a change in the amount of refrigerant discharged to the discharge port 13. Stablize
[0010] An unstable amount of refrigerant discharged through the discharge port 13 causes abnormal operation of the valve, thereby causing noise at the beginning of cycle operation or during cycle operation and reducing compression efficiency

Embodiment Construction

[0026] Hereinafter, a suction muffler of a reciprocating compressor according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. For the same elements as those of the prior art, the same reference numerals refer to the same elements.

[0027] Such as image 3 As shown, a suction muffler 10 for a reciprocating compressor according to a preferred embodiment of the present invention includes a muffler body 11 , a muffler base 20 , and a flow controller 30 .

[0028] The muffler main body 11 has a suction port 12 connected to the suction pipe 8 at a first side of the muffler, and a discharge port 13 spaced or distanced from the suction port 12 by a predetermined interval. In addition, the muffler main body 11 has a resonator 14 formed at the other side of the muffler, and first and second refrigerants formed between the suction port 12 and the discharge port 13 to provide a passage for refrigerant flow throu...

Abstract

The suction muffler of a reciprocating compressor according to the disclosed invention comprises a flow controller for controlling the flow of refrigerant so that a steady amount of refrigerant flows into the suction port of the suction muffler. The flow controller comprises a fixing member having a main refrigerant path, a plurality of refrigerant sub-paths formed to vertically penetrate the fixing member along and adjacent to a circumference of the main refrigerant path at predetermined intervals, and a space with a diameter larger than an imaginary circle made by connecting the plurality of refrigerant sub-paths, formed under the main refrigerant path and the plurality of refrigerant sub-paths. A movable member has a first through hole formed to correspond to the main refrigerant path, and a plurality of second through holes formed at predetermined intervals on the imaginary circumference having a diameter larger than an imaginary circle made by connecting the plurality of refrigerant sub-paths. This movable member is disposed to move between a first location for closing the plurality of refrigerant sub-paths and a second location for opening the plurality of refrigerant sub-paths. A resilient member resiliently urges the movable member towards the second location.

Description

technical field [0001] This invention relates to compressors, and more particularly to suction mufflers for reciprocating compressors. Background technique [0002] Generally, compressors are used to compress low-pressure refrigerant gas evaporated in the refrigeration system of air-conditioning equipment or refrigerators into a high-pressure and high-temperature state, and this process is part of the refrigeration cycle of continuous compression, condensation, expansion and evaporation of refrigerators. [0003] figure 1 A reciprocating compressor is shown as an example of the above-mentioned compressor. [0004] Such as figure 1 As shown, in a general reciprocating compressor, an electric motor 2 provided in a casing 1 rotates a crankshaft 3, thereby driving a connecting rod 4 arranged on an eccentric portion 3a, whereby a connecting rod 4 arranged on a front end of the connecting rod 4 The piston 5 reciprocates in the cylinder 6 for a predetermined number of strokes. ...
