Abstract
The variation of the cylinder capacity is achieved by the fact that the motor crankshaft (7) is provided with a mechanism which varies the eccentricity. This mechanism is powered by hydraulic actuators carried by the shaft (7) and controlled by a circuit external to the frame (1) of the motor. The circuit comprises a rotating coupling (G) and stop valves (Va,VB). Stability of the cylinder capacity may be carried by means of locking mechanisms (13) carried on the shaft.
