Definitions
- the combustion chamber of the invention comprises an assembly constituted by a deformable pocket enveloped by a tubular braid which is also deformable and fed by a combustion mixture.
- This chamber can thus operate according to the thermodynamic principles of the internal combustion engine.
- the tubular braid is advantageously composed of intertwined threads or fibers forming similar pantographs and resulting from a braiding, knitting, knitting or similar technique.
- the threads from which the tubular braid is formed are advantageously synthetic threads, in particular made of aramid.
- the tubular braid is connected to a fixed end piece and to a mobile end piece, said mobile end piece being suitable for being attached by mechanical means, in particular to a crankshaft.
- the assembly constituted by the deformable pocket, the braid and the ends is the equivalent, for a conventional internal combustion engine, of the assembly constituted by the cylinder head, the jacket, the piston and the connecting rod.
- the other main engine components, in particular the crankshaft and the carburetion device are not specific to the invention and will therefore not be detailed.
- FIG. 1 shows a combustion chamber 9 comprising a deformable pocket 3 produced from a flexible tube made of silicone elastomer, which acts as an air chamber, while resisting high temperatures.
- This deformable pocket is wrapped in a deformable braid 4 of chemical textile fibers, in particular of the aramid type.
- This pocket is terminated at its two ends respectively by a fixed tip 1 and a movable tip 2 linked to the braid.
- the movable end piece 2 is suitable for being attached to mechanical means, in the example a crankshaft 10 (shown diagrammatically).
- an intake valve 6 to allow the introduction into the deformable pocket 3 of a combustion mixture (air and fuel) capable of being ignited by a spark triggered by a spark plug 7 housed in the deformable pocket 3 and carried by the fixed tip 1. 5
- the combustion chamber comprises a single intake and exhaust valve 6, but it could be two separate valves as in the case of FIG. 1.
- the next phase or expansion phase ( Figure 5) constitutes the third stage of the engine.
- the valve is closed and the burnt gases expand in the combustion chamber. It follows that the volume of the deformable pocket increases and that the pressure of the burnt gases at high temperature generates a large tensile force on the crankshaft 10 via the movable end piece 2 and the braid 4. This is thus passed from top dead center to bottom dead center.
- the deformable pocket can be completely waterproof, thus eliminating any dynamic sealing.
- the deformable pocket being made of flexible materials, the "sounding board" effect of conventional motors is greatly reduced.
- FIG. 7 shows a wheel 12 integrating a plurality of combustion chambers 9 according to the invention, in the example eleven in number, in a radial star arrangement.
- the wheel 12 has a hollow rim 13 to which is attached one of the ends of each of the deformable pockets, on the intake-ignition side.
- the other end of each of the deformable pockets is connected to an eccentric rotor 14 rotating at the same speed as the wheel (whose direction of rotation is indicated by the arrow R) but along an offset axis and to which the other end is attached of each deformable pocket, on the exhaust side.
