Abstract
A linear compressor comprises a cylinder supported in a hermetic vessel by a supporting mechanism, a piston which is concentric with the cylinder and is slidably supported along its axial direction, and a linear motor for generating thrust force by forming a magnetic passage by a movable portion secured to the piston and a stationary portion secured to the cylinder, in which refrigerant introduced into the hermetic vessel from a suction tube is inhaled and compressed by reciprocating motion of the piston driven by the linear motor and the compressed refrigerant is discharged out from the hermetic vessel, wherein the suction tube is provided in the vicinity of a suction port leading to a compression chamber formed by the piston and the cylinder. With this structure, the refrigerant introduced from the suction tube is not heated by a linear motor, and the compressing efficiency can be prevented from being lowered.
