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
  • the external combustion engine incorporates cylinder 1, formed by a rotating cylinder having both ends counter bevelled at equal angles, which houses the rotary piston 4 having both ends bevelled in parallel, at angle equal to that of cylinder 1
  • the piston 4 has the joint 8 with three degrees of freedom attached to its base at the top, to which the shaft 9 is connected through an arm, having its axis perpendicular to the cylinder 1 base.
  • the joint 8 consists of a pivot with an opening for the arm of the shaft 9 cranked at right angle to slide in.
  • the cylinder 1 is equipped with the medium inlet ports
  • the opening 3 and groove 7 are closed with the piston 4 side surface.
  • the piston 4 moves from the top dead centre to bottom dead centre in a spiral movement by one half of the turn, the opening 3 and groove 7 begin to open, releasing the medium while the opening 2 and groove 6 are closed.
  • the piston 4 continues to move in the same direction in spiral by one half of the turn, reaching the initial top dead centre position.
  • the piston 4 movement is transferred to the output shaft 9 through the joint 8 and the arm.
  • the output shaft 9 has axis perpendicular to the cylinder I base.
  • the engine described above can beneficially be used together with solar collectors, electric dynamos, etc.
  • the external combustion engine according to this invention is particularly applicable for low-output and low-speed engines.
