Abstract:
A linear compressor comprising:a cylinder, comprising a brim, a boss projecting from the brim and a cylindrical body for holding a piston, supported in a hermetic vessel by a supporting mechanism,a piston which is concentric with said cylinder and is slidably supported along its axial direction,a space for forming a compression chamber in which a piston head is disposed, said space formed in the boss,a suction port provided at a side of the brim, the suction port in communication with said space,a cylinder bore formed in the cylindrical body, the cylinder bore in communication with said space and a rear end thereof is opened, anda linear motor for generating thrust force by forming a magnetic passage by a movable portion secured to said piston and a stationary portion disposed at an outer periphery of the cylindrical body and secured to the brim, in which refrigerant introduced into said hermetic vessel from a suction tube is inhaled and compressed by reciprocating motion of said piston driven by said linear motor and the compressed refrigerant is discharged out from said hermetic vessel, where said suction tube is provided in the vicinity of said suction port leading to a compression chamber formed by said piston and said cylinder.
