Abstract (en)
[origin: EP1484474A1] The endothermic 4-stroke rotating pistons engine comprises: a stator having an internal stator chamber provided with a fluid exhaust pipe and a fluid suction duct, a drive shaft traversing said chamber coaxially, and a rotor connected to the drive shaft and during its rotation having surfaces facing on parts of the surface of the stator chamber. <??>The engine is characterized in that the rotor comprises rods functioning as cranks, each with one end connected rigidly to the drive shaft and with the other end hinged to a respective prismatically shaped piston, said piston having one convex face surface ending on two opposite sides with two apical rectilinear edges parallel to the axis of the axis of the drive shaft, with said face always facing parts of the surface of the stator chamber during rotation of the drive shaft and displaying a curvature never greater than the curvature of said parts, and in that the stator chamber displays a cross section with ovoidal profile symmetrical with two axes perpendicular to each other and shaped to ensure for each position of the rotor a sealed contact with said apical edges. <IMAGE>
