Problems solved by technology

[0011] Because in order to make the above-mentioned piston 6 reciprocate at the same distance, it is necessary to set the resonant spring 7A and the resonant spring 7B having the same length at both ends of the above-mentioned piston 6, so the above-mentioned back cover supporting the above-mentioned resonant spring 7A and the resonant spring 7B is 2 increases, resulting in an increase in the overall volume of the compressor

Abstract

The reciprocating compressor consists of sealed container, frame, cylinder, reciprocating motor, piston and resonant spring. The frame is set inside the sealed container and has back cover, the reciprocating motor comprising inner and outer stator assembly and rotor magnet assembly is installed on the inner side of the back cover, the cylinder is inserted into the through hole in the frame, and the piston is combined with the magnet assembly and inserted into the cylinder for linear reciprocation. There are the first fixing part and the second fixing part at the back of the frame and the piston separately for fixing the two ends of resonant spring separately. The present invention can reduce the number of the resonant springs and reduce the volume of the compressor.

Description

technical field [0001] The invention relates to a reciprocating compressor, in particular to a reciprocating compressor whose overall machine volume can be miniaturized. Background technique [0002] A general reciprocating compressor is a compressor that combines a piston with a magnet assembly that forms the rotor of a reciprocating motor instead of a crankshaft, and makes the piston and the magnet assembly reciprocate linearly to suck, compress, and discharge fluid. [0003] figure 1 It is a longitudinal section view of a reciprocating compressor in the prior art. [0004] Such as figure 1 As shown, the prior art reciprocating compressor includes the following structures: frame 1, back cover 2, cylinder 3, inner stator assembly 4A, outer stator assembly 4B, magnet assembly 5, piston 6, inner resonance spring 7A , Outer resonant spring 7B and discharge valve assembly 8 . The above-mentioned annular frame 1 is arranged laterally inside the airtight container V; the abov...
