<p>An improved rotary internal combustion engine comprising a cylindrical chamber (1) in which two-double sector walls (2,3,4,5) rotating about a driving-shaft (12) coaxial with it are housed and where intake and exhaust ports (22,23) as well as ignition means (24) are provided for. A first double sector wall (2,3) comprises a first sleeve (6) with which there are rotatably engaged the driving-shaft (12) and a second sleeve (7) integral to the other double sector wall (4,5). Each sleeve (6,7) pivotally engages (10,11) at one end with a connecting rod (20,21) supporting a pin (18,19) which extends from a throw (25,26) of a planetary gear shaft (15,16) of an epiciclic train keyed on said driving-shaft (12) and on a crankcase (13) flanged to the cylindrical chamber (1). Inside the latter the double sector walls (2,3,4,5) define four variable volume chambers (31,32,33,34) in everyone of which, during a complete revolution of the driving-shaft (12) about its axis, the four strokes of intake of mixture, compression, combustion and exhaust occur. <IMAGE></p> |
