<p>A driving rod for the piston of a reciprocating compressor of the type that comprises: a cylinder block defining a compression chamber; a piston reciprocating within the compression chamber; a driving means to apply reciprocating forces to the piston; and a driving rod disposed between the piston and the driving means and comprising a number, greater than 1, of rods disposed side by side along the axis of the driving rod and each presenting a cross-section that is dimensioned and configured to impart to the driving rod, jointly with the other rods, a required axial rigidity and a flexibility, in at least one direction transversal to the axis of the driving rod, sufficient to absorb, at least substantially, the forces exerted on the piston by the driving rod and by the driving means.</p> |
