TWO-PARTS TELESCOPIC CONNECTING ROD FOR ALTERNATIVE COMPRESSORS AND METHOD OF ASSEMBLING TWO-PARTS TELESCOPIC CONNECTING ROD IN ALTERNATIVE COMPRESSORS

摘要

PROBLEM TO BE SOLVED: To provide a method of mounting a connecting rod having two-parts and telescopic engagement in an alternative compressor.SOLUTION: A connecting rod includes a first portion of a connecting rod 10 to be mounted on an eccentric pin 5 of a crankshaft 4 of a compressor and a second portion of a connecting rod 20 to be articulated in a reciprocating piston 6 within a cylinder 2. One of the first and second portions of the connecting rod includes a tubular stem portion 12 that receives, telescopically and loosely, and retains, by radial inward deformation, a portion 22 of the engagement stem of the other portion of the connecting rod, the stem portions being held together, in an axial and rotational alignment condition, before being attached by fixation means 30a in a relative axial positioning form, which results in a portion of the compression chamber and a corresponding portion of dead volume in the condition of an upper dead point of the piston.SELECTED DRAWING: Figure 1
