BACKGROUND OF THE INVENTION

(0001) This invention relates to improvement of former patented my rotary internal combustion engine, patent LT Nr 5238.

(0002) The rotary internal combustion engine, known to the applicant, having a multi stage axial air compression rotor, valve which alternatively filling up the combustors with the compressed air and closing them, where after sprincled with the compressed fuel achieves combustion, generating high compression gas, which flows through the cascade of turbines, rotating rotor.

(0003) This engine has next defects:

The axial compression impellers generates insufficient compression, therefore for achievment of proper compression requires big number of impellers.

Power rotor with compressor are joined by the teeth connection, which is placed on the end of engine shaft. They rotates on the separate bearings affected by the high temperature, therefore requires to be cooled by oil supplied by oil pump.

This system of gearwheels are not be able to assure needed rotational speed for starter-generator, fuel and oil pums.

A teeth sealing, which is arranged for stopping of gas penetration between of stationary and rotating surfaces, can not asure proper gas stopping. OBJECT OF THE INVENTION

(0004) Accordingly it is an object of the present invention to provide improvement of rotary internal combustion engine by changing big number inefficient axial compression impellers onto few more efficient centrifugal compression impellers. Another purpose of this invention is to replace the complicated gearwheel system, which do not assure proper rotational speed for starter - generator, fuel and oil pumps and to do reducer, generating needed rotational speed for different devices, also on the outer wall trough bearings mounting a main shaft, on the upside locating starter-generator and fuel pump. The next purpose of the invention is instead of two separate rotating compressor and power rotors, having by high temperature affected and by oil cooled bearings, is to arrange a main shaft, with by left screw mounted centrifugal air compression impellers and hollow impeller on one end, on the other end having mounted by teeth connection two power rotors, comprising cascade of turbines and alternatively air filling up valve between them. The other purpose of the invention is to assure gas flow stopping between stationary and rotating surfaces.

SUMMARY OF THE INVENTION

(0005) The above noted objects are accomplished by the provided improved rotary internal combustion engine, comprising a main shaft with left screw mounted centrifugal air compression impellers and hollow impeller on the one end and by the teeth connection mounted two power rotors, comprising a cascade of power turbines and alternatively air filling up valve between them on the other end. (0006) The main shaft is mounted trough bearings into stabilizer, other end into outer wall of reducer, which is made for replacing the complicated system of gearwheels. These bearings are affected by low temperature, therefore any cooling by oil became not required. (0007) One comer of teeth in the barrier sealings need to cut on thirty degrees and nascent emptiness to fill by mixture of oil with granules of graphite. These granules pushing by gas compression will fully close the gap between stationary and rotating surfaces, generating no friction.
