Abstract
Counterbalancing device in a rotary machine comprising at least one piston axially movable in a cylinder, such as a heat engine and equipped per cylinder with at least one rotating distributor. The distributor, on the one hand, is driven in rotation at the same angular speed as the crankshaft of the machine and in the opposite direction to it and, on the other hand, comprises a counterbalancing compensating mass, of at least one part of the primary inertia of the piston-connecting rod-crank assembly corresponding to the cylinder. Application to the counterbalancing of monocylindrical engines with a crankshaft of reduced bulkiness.
