Definitions

• the invention relates to an explosion turbine provided with a gas distribution system by rotary discs or by sliding drawers.
• the invention solves the problems by creating an explosion turbine equipped with centrifugal or axial compressors, each phase of the thermodynamic cycle of which is carried out fully with disc or drawer distributors while offering the minimum of gas flow resistance as well as a variation of the speed on demand thanks to an electric motor or electromagnets.
• the advantages obtained essentially consist in obtaining an independent explosion turbine, the thermodynamic cycle of which is carried out with maximum efficiency with an instantaneous speed variation.
• the drawings representing only one embodiment include: Figure 1, a longitudinal section of the turbine. Figures 2,3,5 and 6 of the cross sections of the gas distributors along AB of this same turbine. Figure 4 an electrical distributor.
• the thermodynamic cycle of the explosion turbine is defined in 2 stages 1st teaos: Admission-Compression
• the compressor (1) sends compressed air into the volute (6), regulated at a pressure determined by the valve (7). This air passes through the orifices of the intake distributor (8) in the combustion chambers (9) 2nd stage: Explosion-Detent-Sweep Explosion:
• the intake distributor (8) closes, the expansion valve (10) always closed. Fuel injection by the injector (14), ignition of the gas mixture by the spark plugs (15), combustion, rise in temperature and pressure. Relaxation:
• the expansion valve (10) opens.
• the intake distributor (8) opens, the expansion valve (10) always open.
• the fresh air coming from the compressor sweeps the remainder of the burnt gases through the openings of the intake distributor (8) which has just opened.
• the expansion valve (10) closes, the intake valve (8) continues to supply fresh air to the chamber (9) and the cycle begins again.
• the electric motor (11) with its speed variations determines the number of explosions thus performing the role of accelerator, it simultaneously controls the ignition and the injection of fuel.
• the intake (8) and expansion (10) distributors are identical and are placed upstream and downstream of the combustion chambers (9).
• the intake (8) and expansion (10) distributors are each formed (FIG. 2) of two fixed discs (16) and (17) between which a rotating disc (18) on a central ring moves with gentle friction ( 19).
• the outer ring (20) assembles the discs (16) and (17).
• the discs (lô) and (17) have one or more orifices (21) located at the assembly opposite one another.
• the quantity of these orifices (21) corresponds to the number of combustion chambers (9) of the turbine.
• the tightness of the intake or expansion orifices (21) on the combustion chamber side is ensured by circular segments (22) floating on circular springs (23) and friction on the rotary disc (18).
• the segment (22) may have in its middle a groove (24) which would divide it in two.
• the tightness of the intake and expansion side is ensured by two projections (25) in the form of a circular segment around the disc, which allows the minimum of friction to be obtained.
• the rotary disc (18) has one or more openings (26) which, once opposite the orifices (21) of the fixed discs (16) and (17) ensure the admission or the expansion of the combustion chambers (9).
• the rotating discs (18) have teeth (27) on their periphery which mesh with the pinions (13) driven together by the drive shaft (12) and the variable speed electric motor (11).
• the lights (26) of the rotary discs (18) for intake and expansion are identical, in the assembly they overlap slightly (hatched part) which allows scanning at the end of the cycle.
• the combustion chambers (9) are supplied one after the other, with two supply lights of two diametrically opposed combustion chambers, with three lights supply in triangle or star, with four in square, this which gives multiple combinations depending on the number of rooms.
• the rotary discs (18) have sodium in their middle where they are cooled in air by ventilation (28).
• a source of air from the compressor (1) supplies the interior of the rotating disc (18) across the central ring (19).
• Internal ribs (29) channel the air by licking the lights (26) to exit on the periphery like a rotary jet.
• the discs (16) and d7) are cooled with air by means of fins or with water;
• the discs (18) are lubricated by two oil inlets (30) on the combustion chamber side and by two inlets (30) in the projections (25) on the intake and expansion side.
• the drive pinions (13)) are oiled by the fallout and evacuation takes place through the orifice (31).
• the intake (8) and expansion (10) distributors with sliding drawers are the same and formed (FIG. 3) of two identical fixed rectangular plates (32) and (33) each having an orifice (34) located at the assembly opposite and around one of them (the one on the combustion chamber side) is a circular sealing segment (22) floating on a circular spring (23) identical to that of the rotary disc distributors.
• the sliding drawer (35) has in its center at the place where the explosion occurs as well as on the other face, a cavity (37) equal to the diameter of the orifice (34) on the chamber side and larger by l 'other side to obtain, the minimum friction.
• the sliding drawer (35) in its reciprocating movement obstructs or releases the orifices (34) for admission and expansion of the chambers (9).
• the reciprocating movement of these sliding drawers (35) is done by means of a rod (38) controlled by an electromagnet (39) itself controlled by a rotary electrical distributor (40) ( Figure 4).
• the sliding drawers (35) are lubricated by two oil inlets (41), one on each side over the thickness of the drawer and evacuation through the orifice (42).
• the sliding drawers (35) can also be controlled by cams (43) (FIG. 5) driven by the motor (11) by means of the axis (44)
• cams (43) (FIG. 5) driven by the motor (11) by means of the axis (44)
• the particularity of this cam (43) is, that it has all around its profile a groove (45) in which the pins (46) slide with a roller (47) fixed on the sliding drawers (35).
• Two sliding drawers (35) are coupled on the same cam ( Figure 6) which allows two combustion chambers (9) to work alternately.
• the relationship between the cams is made by means of a toothed rubber belt (48).
• the cam (43) is lubricated by two oil inlets (49), one on each side and the discharge through the orifice (50).
• the sliding drawers (35) have sodium in their middle and the plates (32) and (33) are cooled with air by means of fins or with water.
• the turbine object of the invention can be used in cars, aviation, the navy and in industry for the production of electricity.
