All engines have at about the time of their largest release of force as a result of the crankshaft torque generation lever arm length goes to 00 and as a result generates almost no torque. 4. In contrast to all types of engines, the WWKM develops power, torque and thus power in every angular position, it is a true one-stroke. Even as a double system, the WWKM is able to deliver only slightly fluctuating torque.
  • the WWKM technology is predestined for the production of very high power with high torques and low speeds.
  • the WWKM technology is used to drive always the same speed and power, then, if it has a positive influence on the efficiency, a conventional steam boiler can be used to generate propellant gas.
  • the reactor technology shown here allows a relatively fast speed or power change.
  • the WWKM technology will be predestined after its successfully completed development phase to be used as a prime mover for power plants, ships or locomotives. It will make a significant contribution to improving these facilities, especially with regard to economic and ecological operation.

Abstract

L'invention concerne un dispositif de production de gaz propulseur destiné à produire un gaz propulseur sous pression en vue d'obtenir un travail mécanique. L'invention concerne en outre un procédé de production d'un gaz propulseur sous pression de manière à obtenir un travail mécanique en recourant à un dispositif de production de gaz propulseur doté d'un récipient sous pression de gaz propulseur, d'une chambre de combustion reliée au récipient sous pression de gaz propulseur et d'une amenée de propulseur secondaire destinée à introduire un propulseur secondaire dans le récipient sous pression de gaz propulseur. L'invention concerne en outre une machine de détente qui convertit l'énergie contenue dans le gaz propulseur sous pression en un déplacement mécanique, en particulier un déplacement de rotation, et qui présente un premier ensemble partiel de détente, ainsi qu'un procédé d'utilisation d'une machine de détente. L'invention concerne également une machine thermodynamique destinée à produire un déplacement mécanique en recourant à un combustible, un compresseur qui comprime un gaz de processus, en particulier de l'air, ainsi qu'un évaporateur qui produit de la vapeur d'eau à partir d'eau.
