LINEAR COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a linear compressor having high efficiency and high reliability, by previously deviating the center of length in the axial direction of a movable part connected to a piston to the compression chamber side relating to the center of length in the axial direction of a fixed part, and by almost conforming the center of length in the axial direction of the movable part of a linear motor to the center of length in the axial direction of the fixed part when operating. SOLUTION: The linear compressor comprises: a cylinder supported by a support mechanism part in a closed vessel; a piston with the same axial center to the cylinder to be supported movably along the axial direction thereof to be formed with a compression chamber between itself and the cylinder; a spring member giving force in the axial direction to the piston; and a linear motor part having a movable part connected to the piston through a hold member and a fixed part fixed to the cylinder for forming a magnetic path between itself and this movable part to make the piston generate thrust moved along its axial direction. The linear compressor is characterized by providing a conformity means conforming the center of length in the axial direction of the fixed part to the center of length in the axial direction of the movable part.
