ABSTRACT:
Hot gas engine units of the type having four parallel cylinders arranged in two parallel rows of two cylinders per row may be effectively balanced by a minimum of counterweight masses. The engine pistons are connected to two parallel crank shafts and four primary counterweights are positioned on the crankshafts each diametrically opposite a respective crank. The crankshafts engage a common gear wheel rotating opposite to but at the same angular speed as the two crank shafts, and the gear wheel is mounted on a third shaft parallel to the two crank shafts. Secondary counterweights including at least two axially spaced, oppositely directed secondary counterweights positioned on the third shaft are used to cancel the moment about the engine vertical axis produced by the primary counterweights.
