PISTON COMPRESSOR WITH A TWO-PIECE CONNECTING ROD AND METHOD FOR ASSEMBLING A TWO-PART CONNECTING ROD

摘要

A two-piece connecting rod for a reciprocating compressor and method for assembling a two-piece connecting rod, said connecting rod comprising an engaging portion (21), which is provided in one of the parts defined by a first connecting rod portion (10), to be mounted to the eccentric (6) of a crankshaft (4) of the compressor, and by a second connecting rod portion (20), to be articulated to a piston (8) reciprocating inside a cylinder (7), which is closed by a cylinder head (9); and a guide portion (11) provided in the other of said parts, to be slidingly coupled with the engaging portion (21); and a fixation means, applied to the coupling region between the engaging portion (21) and the guide portion (11), with the first connecting rod portion (10) being mounted to the eccentric (6) and with the second connecting rod portion (20) being mounted to the piston (8) lodged in the cylinder (7), in order to lock said portions against relative displacements in a position which results in a predetermined axial distance between the top face of the piston, in the upper dead point condition, and the inner face of the cylinder head (9) of the cylinder (7) of the compressor which is being mounted.
