DEVICE FOR CONTROLLING THE PHASE ANGLE BETWEEN A FIRST AND A SECOND CRANKSHAFT
The present invention relates to a device for regulating the phase angle between a first and a second crankshaft of an internal combustion engine. Said internal combustion engine comprises primary cylinders which communicate with secondary cylinders and in every primary cylinder there is movably arranged a primary piston which is connected to the first crankshaft and in every secondary cylinder there is movably arranged a secondary piston which is connected to the second crankshaft. Said first and second crankshafts are connected to each other by means of a transmission with the device comprising a crankshaft extension for obtaining the control of the phase angle, said extension being fixed against rotation and displaceably connected to one of said crankshafts and via a grooved portion rotationally connected to the second of said crankshafts. When the crankshaft extension in displaced rotation is obtained in said grooved portion which results in a corresponding phase angle shift.
