Method and apparatus for attaching a piston to a connecting rod in a compressor

摘要

A piston of a compressor is connected to a motor-driven connecting rod by a piston pin which is inserted into an aperture of the piston and into an opening of the connecting rod which is aligned with the aperture. A first support pin disposed in the piston extends across the aperture to limit the insertion of the piston pin. Then, a second support pin disposed in the piston is pushed manually across the aperture, whereby the piston pin is trapped between the two support pins and cannot be dislodged during operation of the compressor.
