Abstract of Disclosure Method and device for regulating the phase angle between a first and a second crankshaft of an internal combustion engine. The engine includes primary cylinders that communicate with secondary cylinders and in every primary cylinder there is movably arranged a primary piston that is connected to the first crankshaft and in every secondary cylinder there is movably arranged a secondary piston that is connected to the second crankshaft. The first and second crankshafts are connected to each other by means of a transmission adapted with the device that includes a crankshaft extension for obtaining the control of the phase angle, the extension being fixed against rotation and displaceably connected to one of the crankshafts and via a grooved portion rotationally connected to the second of the crankshafts. When the crankshaft extension in displaced, rotation is obtained in the grooved portion that results in a corresponding phase angle shift.
A device for controlling the phase angle between a first and a second crankshaft of an internal combustion engine, said internal combustion engine comprising at least one primary cylinder which communicates with at least one secondary cylinder, in each primary cylinder there being movingly arranged a primary piston which is connected to the first crankshaft, and in every secondary cylinder there being movingly arranged a secondary piston which is connected to the second crankshaft, with said first and second crankshaft being connected to each other by means of a transmission, means for obtaining the phase shift control, and a crankshaft extension intended for said phase angle control, which is fixedly connected against rotation to one of said crankshafts and rotationally attached to the second of said crankshafts and further comprising a hydraulic piston arranged in a housing, said hydraulic piston being arranged to obtain an axial displacement of the crankshaft extension relative to one of said crankshafts, said hydraulic piston being arranged to surround the crankshaft extension.
A device for manipulating the phase angle between two crankshafts of an internal combustion engine, said device comprising:
