Definitions

• the present invention relates to rotary engines with gasoline or compressed air based on the rotational movement of a rotor, and relates in particular to a rotary motor with a circular rotor.
• the engines of the vehicles used today are internal combustion engines comprising reciprocating pistons in which the engine force is produced by the explosion of a mixture of air and fuel such as fuel. petrol.
• Each piston that is in a cylinder is pushed violently by the explosion ert causes the rotation of a crankshaft via a connecting rod.
• these engines have a major disadvantage that the stroke of the piston in the cylinder is limited to about 8 cm.
• the lever arm of the crankshaft is limited to about 4 cm, and therefore, all the motor force is on these 4 cm of the lever arm, which significantly limits the engine torque.
• the rotary engine has a slightly more complex operation than the traditional piston engine. Unlike an internal combustion engine that operates through pistons, the rotary engine uses a rotor. Unlike the internal combustion engine, the rotary engine has neither crankshaft nor crankshaft. There are advantages to using a rotary engine rather than the reciprocating engine. First, this engine having no reciprocating parts, its balancing is excellent, which ensures a private operation of vibrations, thereby limiting the noise level regardless of the speed of rotation. Then, this engine causes less vibration since all the parts follow the same path, because they turn in the same direction. In addition, since there are fewer moving parts in the engine, the rotary motor is more reliable.

But this would require having 4 recesses in each flange instead of 2 as is the case in the embodiment described above. One could even have a single flanged element rotating at the same speed as the rotor. But the diameter of the flanged element should be double, which would increase the size.

As the speed increases after the engine has been started, the springs compress with centrifugal force and the pistons move slightly away from the stator surface. When the optimum speed is reached, this speed is such that there is a speed-induced sealing without the need for contact. When the engine is stopped, the pistons retract to come into contact with the stator surface and seal at startup. Since there is no friction on the rotor when it rotates, it is not necessary to put lubricant.
