  • Two parts telescopic connecting rod for alternative compressors and method of assembling two-parts telescopic connecting rod in alternative compressors
    Patent number: 10584693
    Abstract: The connecting rod includes a first portion of the connecting rod to be mounted on the eccentric pin of a crankshaft of the compressor and a second portion of the connecting rod to be articulated in a reciprocating piston within a cylinder. One of the first and second portions of the connecting rod includes a tubular stem portion that receives, telescopically and loosely, and retains, by radial inward deformation, a portion of the engagement stem of the other portion of the connecting rod, said stem portions being held together, in an axial and rotational alignment condition, before being attached by a fixation mean in a relative axial positioning, which results in a portion of the compression chamber and a respective portion of dead volume in the condition of upper dead point of the piston.
