Abstract
A linear compressor includes a casing having a suction pipe and a discharge pipe and a unit including a cylinder formed therein and an inner stator assembly and an outer stator assembly installed on the exterior of the cylinder and a magnet assembly inserted into the certain void of the inner and outer stator assembly for performing a reciprocating motion linearly and a piston connected to the magnet assembly by forming a connection portion and a gas through hole formed in the connection portion of the magnet assembly and piston, which is capable of decreasing a flow resistance by forming the gas through holes in the connection portion of the magnet assembly and the piston and decreasing the specific volume of the suction coolant by making the coolant gas filled the both area of the connection portion flow reciprocally in the reciprocating motion of the piston.
