<p>PURPOSE: An airtight compressor is provided to simplify the assembling structure of a piston and a connecting rod and to effectively reduce the deformation of the outer part of the piston. CONSTITUTION: An airtight compressor comprises a connecting rod(60), a space, a piston(22), and a piston pin(70). A first pinhole(62) is formed on one end of the connecting rod. The space accepts one end of the connecting rod, on which the first pinhole has been formed. The piston comprises a pair of second pinholes, which are respectively formed on both sides of the space. The piston fin is connected to the first pinhole and the second pinhole and connects the connecting rod to the piston. The piston pin is forcibly pressed to one of the second pinholes, the second pinhole, to which the piston pin has been pressed, is divided into a first section adjacent to the center of the piston and a second section adjacent to the outer part of the piston, a sliding tolerance is formed between the first section and the piston pin and a pressing tolerance is formed between the second section and the piston pin.</p> |
