Embodiment Construction

[0046] Fig. 3 is a detailed perspective view showing a suction muffler equipped with a Tesla valve of the present invention, and Fig. 4 is a cross-sectional view showing a Tesla valve mounted in a suction muffler of the present invention.

[0047] Referring to FIGS. 3 and 4 , the present invention consists of a suction portion 161 installed above the suction valve 180 for passing through the suction valve 180 and the cylinder after the low-temperature and low-pressure refrigerant gas is ejected from the evaporator (not shown). The suction muffler 340 that reduces composite noise including vibration noise, valve resonance, and refrigerant gas flow noise and pulsation noise generated by the suction valve 180 when the suction cylinder 160 is sucked in, and has two suction mufflers inside the suction muffler 340 The distribution paths 351 and 352 are constituted by the Tesla valve 350 that prevents the refrigerant gas from flowing back into the suction muffler 340 from the suction ...

Abstract

The invention relates to a suction muffler in a reciprocating compressor. The suction muffler is installed over a suction valve in order to attenuate complex sound pressure (noise) such as vibrational noise, valve sonance and flowing noise and pulsative noise which is produced from the suction valve when refrigerant gas in low temperature and pressure ejected from an evaporator is sucked into a cylinder via the suction valve and a suction portion of the cylinder. Further, a Tesla valve having the two distribution paths is mounted within the suction muffler in order to attenuate the complex sound pressure (noise) such as vibrational noise, valve sonance and flowing noise and pulsative noise produced from the suction valve while prevent the reflow of the refrigerant gas into the suction muffler from the suction valve. The Tesla valve prevents the reflow of the refrigerant gas into the suction muffler to enhance the cooling ability of the compressor while enhance the attenuation effect of the complex sound pressure (noise) transferred from the suction valve.

Description

technical field [0001] The present invention relates to a suction muffler in a hermetic reciprocating compressor, and in particular, provides a valve structure having a distribution path inside the suction muffler to facilitate the flow and attenuation of refrigerant gas Various noises generated by the suction valve. Background technique [0002] As known to those skilled in the art, compressors for converting mechanical energy into compressive energy for compressed fluids can be classified into: reciprocating compressors, screw-type (scroll-type) compressors, centrifugal (turbine) compressors , Vane (rotary) compressors and so on. [0003] In the reciprocating compressor (so-called hermetic reciprocating compressor) among the above-mentioned compressors, the drive motor drives the crankshaft with rotational force, which is converted into linear reciprocating motion by the connecting rod connected to the crankshaft, so that the piston sucks Low-temperature and low-pressure...
