  • the engine is adapted with both turbine and piston, and is constructed in such a way that the piston fit directly to the blades of the turbine engine under demarcation of a ring-shaped combustion chamber around the turbine blades.
  • the piston fit directly to the blades of the turbine engine under demarcation of a ring-shaped combustion chamber around the turbine blades.
  • a very direct effect of the combustion pressure on the piston and the turbine blades is partly achieved a very direct effect of the combustion pressure on the piston and the turbine blades, and partly a direct effect of the combustion products kine ⁇ tic and dynamic energy in the turbine.
  • the result is a motor with optimum ter ic degree of effect, i.e.good fuel economy, with good tough drawing qualities because of the piston function, and with high effect compared to the weight on account of the turbine function.

  • the rotor is supplied with radius placed turbine blades la (fig. 6), which move a ring-shaped com ⁇ bustion chamber 6 in the turbine house 2.
  • On the sides of the rotor are supplied a number of air leading sheets 7. The shape of these is chosen, so the air is forced from the centre of the rotor and out against the cumbu ⁇ - ' tion chamber 6 during the rotation.

  • a blend of gasoli- ne and air in the combustion chamber is ⁇ ucted via the suction channels 9 in the rotor 1.
  • the piston moves towards the rotor again at the same time as the suction valves are closed.
  • the blend of gas which is in the combustion chamber, is compressed.
  • the compressed gas ignite and combust regularly in the combustion chamber.
  • the gas pressure will drive the ro ⁇ tor round, as the pressure will influence on the turbine blades in such a way that the resulting body on the bla ⁇ des will force a turning factor on the rotor.
  • con ⁇ tribute the slanting positions of the blades and alterna ⁇ tely right and left in proportion to the rotation level (fig. 6).
  • the gas pressure on the piston will con- tribute to increase the effect and factor progress of the engine.
  • the piston moves towards the rotor again and the ex- pansioned and in some degree cooled combustion gasses are led out through the exhaust channels of the engine via the rotation channels 9 and the turning valve 10.

Abstract

La présente invention se rapporte à un moteur à combustion interne qui combine les modes de fonctionnement d'un moteur à quatre temps et d'un moteur à turbine. Le moteur à combustion interne comprend une turbine (1), un logement (2) et un piston en forme d'anneau (3) effectuant un déplacement relatif dans une chambre de combustion en forme d'anneau qui entoure les ailettes (1a) de la turbine. Un accouplement mécanique servant à synchroniser le mouvement alternatif du piston avec le mouvement rotatif de la turbine est disposé entre la turbine et le piston. Le moteur effectue de préférence le cycle des quatre temps en un seul tour. Il se caractérise également par sa simplicité, sa robustesse et par des caractéristiques de rotation à faible vitesse favorables. Il effectue une combustion propre qui répond à des normes antipollution sévères sans l'utilisation d'un catalyseur.
