ABSTRACT:
A preferably hermetic motor-compressor unit comprises a usual drive shaft operated by a known electric motor and acting on a compressor section (1) for a fluid, for example a refrigerant fluid, comprising a piston (3) associated with a connecting rod (2) operated by the said shaft, said piston (3) moving within the bore (23) of a corresponding cylinder (4) in which it compresses said fluid. With the connecting rod (2) there are associated means (11) arranged to engage with counter-means (13) associated with the piston (3) so as to connect this latter to the connecting rod (2), retention means (20) being provided to maintain the engagement between said means and counter-means.
