In a compressor which has a connecting rod comprising: a second eye (31) connected to the crank pin (12) and a crankshaft (7) and including a radial projection (32) with a longitudinal slot (33), said longitudinal slot (33) having at least two end faces (35) and two opposite lateral faces (34); a fi
In a compressor which has a connecting rod comprising: a second eye (31) connected to the crank pin (12) and a crankshaft (7) and including a radial projection (32) with a longitudinal slot (33), said longitudinal slot (33) having at least two end faces (35) and two opposite lateral faces (34); a first eye (21) connected to the piston and including a rod (22) with an end portion, said end portion having at least two end faces (25) and two opposite lateral faces (24), said end portion being fitted in said longitudinal slot (33) so as to bring the end faces of the slot (33) and the rod (22) into contact therefore defining the axial distance between the centers of the eyes. According to the invention a clamp (40) preferably of spring steel, is fitted in the housing (28, 29, 38, 39) of the radial projection (32) of the second eye (31) and the end portion of the rod (22). The clamp, (40) due to its elastic action, is designed in such a way as to press both parts (20, 30) of the connecting rod (20, 30) to a position of minimum axial distance between the centers of the eyes (21, 31) and fastening these parts (20, 30) in a relative and predetermined position of the eyes (21, 31).
