Definitions

  • the invention concerns the external combustion engine consisting of at least one cylinder with a rotary piston.
  • the external combustion engine according to this invention incorporating at least one cylinder with a rotary piston, is capable of eliminating the above disadvantages.
  • the substance of this engine is the cylinder, formed by rotating cylinder with both ends counter bevelled at equal angles, which houses a rotary piston with both ends bevelled in parallel, at angle equal to that of cylinder.
  • the piston has a joint with at least three degrees of freedom attached to its base at the top, to which a shaft with axis perpendicular to the cylinder base is connected through an arm.
  • the joint advantageously consists of a pivot with an opening for the arm of the shaft cranked at ⁇ ght angle to slide in
  • the cylinder advantageously employees the inlet and outlet ports while the piston employees piston rings
  • the cylinder may further employ grooves for the medium intake and other grooves for the medium off-take, both being positioned in parallel with the cylinder base

Abstract

L'invention concerne un moteur à combustion externe qui comprend au moins un cylindre (1) doté d'un piston rotatif (4). Le cylindre (1) est constitué d'un cylindre rotatif présentant deux extrémités qui sont inclinées à angles égaux à l'inverse et loge un piston rotatif (4) dont les deux extrémités sont inclinées de manière parallèle à un angle égal à celui du cylindre (1). Le piston (4) comporte un joint (8) qui présente au moins trois degrés de liberté et qui est fixé à sa base sur la partie supérieure, à laquelle un arbre (9), présentant un axe perpendiculaire à la base du cylindre, est relié par l'intermédiaire d'un bras.
