SPRING SUPPORT STRUCTURE FOR RECIPROCATING COMPRESSOR

摘要

A spring support (100) structure for reciprocating compressor having a frame unit (40) elastically supported inside a closed container (10); a reciprocating motor (20) fixed at the frame unit (40); a compression unit (30) having a piston (31) combined to an armature (22) of the reciprocating motor (20) and a cylinder (32) into which the piston (31) is slidably inserted to be fixed at the frame unit (40); and a spring unit (100) supporting a spring support (110) provided at the armature (22) or the piston (31) and guiding a reciprocal movement of the piston (31), wherein the spring unit (100) includes a plurality of front springs (51) supporting one side of the spring support (110) in parallel and a plurality of the rear springs (52) supporting the other side of the spring support.(100) Since the front springs and the rear springs (52) elastically supporting both the armature (22) and the piston (31)are arranged in parallel to overlap with each other for a certain range, the horizontal length of the spring is reduced, resulting in that the compressor can be compact.
