Reciprocating motion type compressor using resonance

Abstract

A reciprocating compressor using resonance features that a piston cap less than internal diameter of cylinder is integrated on the end of piston to form a resonator. In the sucking procedure, the resonance of sucked cold medium takes place in said resonator for speeding up the piston and increasing the sucked cold medium. In the compression procedure, said resonance can make speed uniform to increase compression efficiency.

Description

technical field [0001] The invention relates to the field of compressors. Background technique [0002] In general, a compressor is a machine that sucks in fluid, compresses it, and discharges it. It consists of a rotating part that generates a driving force and a compression part that compresses the fluid using the driving force generated by the rotating part. According to the shape of the compression parts, it can be divided into hermetic rotary compressors, hermetic reciprocating compressors, and hermetic sleeve compressors. [0003] figure 1 It is a longitudinal sectional view of a reciprocating compressor structure in the prior art. [0004] As shown in the figure, the prior art reciprocating compressor has a closed container 1 with a closed space, and a rotating part 4 composed of a stator 2 and a rotor 3 is installed. The shaft pressing hole 3a in the center of the rotor 3 is pressed into the rotating shaft 5, and the upper end of the rotating shaft 5 is inserted i...

Problems solved by technology

[0011] However, when the conventional hermetic reciprocating compressor sucks the refrigerant into the compression space 12, when the piston 10 moves from the upper end TDP to the lower end BDP inside the cylinder 9, the speed decreases before reaching the lower end BDP. , the refrigerant cannot be fully sucked in, reducing the amount of compressed and discharged refrigerant, which limits the improvement of compressor efficiency
