Known rotary piston internal combustion engines have distinct disadvantages such as a complex structure and do not use the gas pressure arising during combustion in an optimum manner. Disclosed is a rotary piston internal combustion engine comprising a housing (1), at least one working wheel (2) which can rotate about an axis of rotation (R) in the housing (1), at least one working piston (3) provided on the working wheel (2) and used to suction and compress air or a fuel-air mixture and to convert the gas pressure arising during combustion of a fuel-air mixture into mechanical energy, at least one counter wheel (4) having at least one working piston recess (5), a plurality of rotationally driven first air blades (6) which are used to pre-compress air or a fuel mixture, and at least one combustion chamber (7) used to combust a fuel-air mixture. According to the invention, the at least one combustion chamber (7), when in operation, is continuously formed anew between the working piston (3), the working wheel (2), counter wheel (4) and housing (1) and the first air blades form part of the working wheel (2) in a spoke-like manner, suctioning the fuel air mixture or the air during operation in a substantially parallel position with respect to the axis of rotation (R) of the working wheel by means of said working wheel (2).

Les moteurs à combustion interne à piston rotatif connus présentent certains inconvénients, tel qu'un montage complexe et une exploitation non optimale de la pression gazeuse émanant de la combustion. La présente invention concerne un moteur à combustion interne à piston rotatif comprenant un carter (1), au moins une roue de travail (2), qui peut tourner dans le carter (1) autour d'un axe de rotation (R), au moins un piston de travail (3), qui est pourvu sur ladite roue de travail (2) et permet d'aspirer et de comprimer de l'air ou un mélange air-carburant et de transformer la pression gazeuse émanant de la combustion d'un mélange air-carburant en énergie mécanique, au moins une roue conjuguée (4), qui comprend au moins un logement (5) destiné au piston de travail, un certain nombre de premières pales à air (6), qui peuvent être entraînées en rotation et permettent une pré-compression d'air ou d'un mélange air-carburant, ainsi qu'au moins une chambre de combustion (7), qui permet la combustion d'un mélange air-carburant. Cette chambre à combustion (7), en service, est formée de manière continuellement nouvelle entre le piston de travail (3), la roue de travail (2), la roue conjuguée (4) et le carter (1). Les premières pales à air font partie de la roue de travail (2), sous forme de rayons de roue, et, en service, aspirent le mélange air-carburant ou l'air à travers la roue de travail (2), de manière sensiblement parallèle à l'axe de rotation (R) de la roue de travail (2).
