PURPOSE: A reciprocation compressor is provided to reduce the operation noise by lowering the vibration of a frame by arranging a plurality of cylinders at one frame at a regular interval. CONSTITUTION: A reciprocation compressor comprises followings. A crank shaft(33) includes an eccentric pin eccentric from the center of rotation and is installed at a frame of a sealed container inside to rotate by a motor unit. The cylinder is arranged at the both side around the center of rotation of the crank shaft and includes a compression room inside. Pistons(141,142) is inserted at a plurality of cylinders to compress a refrigerant while reciprocating. A connecting rod changes the rotational motion of the crank shaft into the linear motion of the piston. A connection sleeve(120) is combined with an eccentric pin of the crank shaft. A bearing sleeve(180) is inserted between the eccentric pin and the connection sleeve of the crank shaft. |
