Benefits of technology

[0020] Therefore, it is an object of the present invention to provide a reciprocating compressor capable of moving a resonant spring horizontally and straight forwardly by reducing a torsion moment of the resonant spring, reducing a width of the compressor, and maintaining a concentricity of a driving unit and a compression unit.

Problems solved by technology

Because of this, it is difficult for the piston 124 to keep its linear movement, so performance of a motor is deteriorated.

Abstract

A reciprocating compressor includes a driving unit (16) having an outer stator (26) and an inner stator disposed at a predetermined air gap there between, and a moving member positioned between the outer stator (26) and the inner stator (28) and linearly and reciprocally moved; a compression unit (18) having a cylinder (38) fixed at an inner circumferential surface of the inner stator (28) and a piston (22) linearly moved in the cylinder (38) by being connected to the moving member, a support portion (20) supporting the compression unit (18) and the driving unit (16); and a resonant spring unit positioned (24) at a rear portion of the driving unit (16), disposed at the support portion (20), and inducing a resonant movement of the piston (22). Therefore, a resonant spring (62,64) of the compressor can be moved horizontally and straight forwardly by reducing a torsion moment of the resonant spring (62,64), a width of the compressor can be reduced, and a concentricity of a driving unit (16) and a compression unit can be maintained.

Description

TECHNICAL FIELD [0001] The present invention relates to a reciprocating compressor, and particularly to a reciprocating compressor that can be compact in size and having improved performance. BACKGROUND ART [0002]FIG. 1 is a sectional view showing a reciprocating compressor in accordance with one example of a conventional art. [0003] A conventional reciprocating compressor includes a close casing to which a suction pipe 102 and a discharge pipe 104 are connected respectively; a driving unit 108 disposed in the casing 106 and generating a reciprocal movement force; a compression unit 110 transmitted the reciprocal movement force generated at the driving unit 108 and compressing a fluid; a support portion 112 supporting the driving unit 108 and the compression unit 110. [0004] The driving unit 108 includes an outer stator 116 fixed at the support portion 112 and having a winding coil 114 to which power is applied; an inner stator 118 disposed at an inner circumferential surface of the...
