DESMODROMIC ENDOTHERMIC ROTARY ENGINE WITH EXTERNAL COMBUSTION CHAMBER AT VARIABLE VOLUME

摘要

An endothermic rotary engine with an external combustion chamber with a variable volume, and a piston with round section that rolls inside a cylinder of larger diameter and of equal length, the piston 2 being supported at either end by eccentric mechanisms 5 located between the axis of the rotating piston and the axis of the cylinder. The configuration of intake, compression, expansion and exhaust chambers is obtained by two cross mobile sliders 4 (vanes) of rectangular section that during the rotation slide within specific slots made in the cylinder wall, the sliders remaining in continuous contact with the rotating piston. The cross mobile sliders movement is obtained through a desmodromic system located outside the cylinder and composed by an eccentric that moves two desmodromic tracks bound to the prisms. The engine provides improvement over the prior art in terms of reduced friction, higher rotational speed and improved sealing.
