Abstract

A reciprocating piston engine includes a housing; a cylinder disposed in the housing; a piston guided for reciprocation within the cylinder; a crankshaft connected to the piston for effecting a guided reciprocation thereof within the cylinder; at least two camplates connected to the crankshaft such that they rotate together with the crankshaft, each camplate defining a control contour thereon; two balancing masses operatively coupled to the camplates such that the camplates are effective for actuating respective ones of the balancing masses, each balancing mass comprising a pivoting arm; and coupling means connecting the balancing masses to one another thereby effecting a forced reciprocation thereof as a function of a rotation of the crankshaft. The coupling means include: two pivoting shafts disposed on each side of the crankshaft and extending parallel thereto, each pivoting shaft being connected to at least one balancing mass, each balancing mass being aligned in a direction of a main extension thereof perpendicularly with respect to each pivoting shaft; and coupling components connecting the pivoting shafts to one another.
