Abstract
The present invention provides a reciprocating type compressor using resonance, which has the technical scheme that a piston cap with the internal diameter smaller than that of a cylinder is arranged on the end part of a piston; a resonance part with the volume larger than that of the inlet part is formed between the outer diameter of a piston cap between the piston cap and the piston and the inner diameter of the cylinder; the resonance part is positioned at the inner side of the inlet part; the piston cap is combined with the end part of the piston; the piston cap can be in an elliptical shape; when a suction port generates resonance in the suction process of the countermarch of the piston of the cylinder, the sucked refrigerant flows into the resonance part in order to generate resonance; the increase of the speed of the piston makes the suction volume of the refrigerant increase at the initial stage of suction. The present invention has the advantages that the speed is homogeneous through the resonance in the compression process, the damage caused by overpressure is prevented, and the compression efficiency of the compressor is enhanced.
Description
Technical field
The present invention relates to compressor field.
Background technique
Compressor is to suck fluid to compress the machinery that discharge the back generally speaking, is made of the compression member of the rotatable parts that produce driving force with the driving force compressed fluid that utilizes these rotatable parts to produce.Differentiating forms according to compression member is closed revolution type compressor, closed reciprocating motion type compressor, closed axle sleeve compressor.
Fig. 1 is the sectional arrangement drawing of the reciprocating motion type compressor structure of prior art.
As shown in the figure, the reciprocating motion type compressor of prior art is to have in the closed container 1 of enclosed space the rotatable parts 4 that are made of stator 2 and rotor 3 have been installed.Be pressed into running shaft 5 among the axial compression hand-hole 3a of rotor 3 central authorities, insert among the axle supporting hole 6a upper end of running shaft 5, impact when rotating in order to relax rotor 3, a plurality of springs 6 are supported to have fixed in the lower end of stator 2, connected axle sleeve 7 on the eccentric shaft 5a of the upper end off-centre of running shaft 5, connected on the axle sleeve 7 and convert straight-line connecting rod 8 to rotatablely moving.Body upper one side has cylinder 9, and the inside of this cylinder 9 is provided with compression member 11, and piston 10 links together with the front end of connecting rod 8.
The opening portion of cylinder 9 one sides has been installed refrigerant has been drawn into the compression volume 12 of cylinder 9 or the valve 13 of discharging, and the loam cake 14 that separately sucks refrigerant and discharge refrigerant has been installed in the outside of this valve 13.The lower end of loam cake 14 is communicated with the absorbing silencer 15 that reduces the suction coolant noise, and the upper end is communicated with the exhaust silencer 16 that reduces the noise of discharging refrigerant.
