Abstract:
A linear compressor, comprising:a cylinder block having a first surface with a cylinder receiving a piston while allowing the piston to linearly reciprocate in said cylinder; a cylinder head assembled with a second surface of the cylinder block and used to guide inlet and outlet refrigerant; a movable member connected to the piston and provided with a magnet arranged around the cylinder; a drive unit reciprocating both the piston and the movable member; and an anti-collision device set between the first surface of the cylinder block and an end of the movable member, and used to prevent the piston from moving past an upper dead center position, wherein the anti-collision device comprises an elastic part supported by the first surface of the cylinder block and a portion of the elastic part is spaced apart from the first surface of the cylinder block with a gap therebetween such that the portion of the elastic part, which is spaced apart from the first surface of the cylinder block, collides with the end of the movable member just before the piston moves past the upper dead end position to prevent the piston from colliding with the cylinder head.
