<p>A reciprocating internal combustion engine comprises a crankshaft (4) rotatable relative to the engine block (2) and having at least one crank (4a) with which a piston (6a) is associated for sliding in a cylinder (5a) connected to the block (2). Each piston (6a) is connected to the respective crank (4a) by means of a hypocycloid crank-mechanism device which includes a principal eccentric (10a) rotatable eccentrically relative to the crank (4a) and surrounded by a principal annular member (8a) which is rotatable coaxially relative to the principal eccentric and from which a connecting element (7a) of the respective piston (6a) extends.</p> |
