Abstract

The engine has an annular chamber (101) between rotor (104) and external stator (103). Four crescent-shaped rotors (102) are synchronised with the main rotor and run partly in circular recesses in the stator wall and partly in the annular chamber. These rotors are positioned so as the raised part of the rotor passes their inner surface completes the curvature of the inside of the rotor.

Description

 The present invention consists of a device of mechanical parts rotating on their respective axes, realizing by their designs of shapes and movements of gas chambers with variable volumes, activating the 4-stroke of internal combustion thermal engines The parts constituting the device allow according to their arrangements 4 particular embodiments of this said device. The 4 embodiments are intended for motorization they are rotary 4-stroke thermal motors.

In the conventional design of 4-stroke thermal engines, the basic movements are linear and must be converted into circular movements to be usable. The gases are distributed, 11 is heavy, the parts are numerous, the vibrations are always present, the power supply weakens with the revving up, the noises emitted must be reduced
The device according to the invention overcomes these drawbacks in that the gases exert their thrusts in closed chambers formed on the periphery of a drive shaft exerting a direct engine torque on it in a uniform and continuous movement where gases enter and exit in an uninterrupted flow.

The faces of the parts constituting the chambers are produced as close as possible to one another without undergoing any effort or conceptual mechanical friction between them; these parts are therefore guided lubricated outside the gas chambers
The gases which can escape from the chambers through any play in the parts constituting these said chambers are evacuated towards the upstream or downstream chambers.

Combustion residues cause deposits on the faces of the parts constituting the walls of the chambers and then strengthen the seal.

The thickness of these deposits is constantly adjusted by the abrasive or laminar movements of the moving parts constituting the gas chambers.

 It is not useful to equip the device with a kinetic inertia flywheel.

The motor device is light and compact.

The engine is capable of low or very high revs.

the gases are activated in very hot insulated chambers while the mechanical parts remain temperate.

 Depending on the application affected, the device can be produced according to various particular embodiments.

according to some of these modes one can observe the plotting of torque curves on a rotor turn as fairly straight, thanks to the large number of explosions on the turn and observe a peak of torque very soon after the explosion.

It generates high engine torque, several times greater than its conventional equivalent with equal displacement.

It does not vibrate.

Energy losses due to friction are low
