Definitions

• the invention relates to a rotary compressed air motor essentially comprising:
• a chamber delimited, longitudinally, by the cylindrical walls facing said stator and said rotor and, laterally, by two facing flanges;
• each decompression chamber being delimited, longitudinally, at one end, by a wall, acting as a piston, integral with the rotor and extending to the stator and, at the other end, by a wall, retractable, arranged upstream the corresponding air inlet pipe, integral in translation with the stator and extending to the rotor, associated with a means adapted to make it retractable during the passage of the piston.
• the invention aims to produce a rotary motor of simple, new and original design, making it possible to achieve high yields.
• each air inlet pipe is associated with a means suitable for blowing, into the corresponding decompression chamber, after the passage of the piston over the inlet pipe, a quantity of air of well determined pressure and volume.
• the means adapted to move the retractable wall during the passage of the piston is chosen from mechanical devices with cams, electromechanical relays and pneumatic cylinders;
• the means adapted to move the retractable wall during the passage of the piston is the piston itself which has a shape adapted to disengage said wall during its passage;
• a quantity of air under well defined pressure is chosen from mechanical, electromechanical and pneumatic devices with valves or with valves;
• the means adapted to breathe into the decompression chamber, after the passage of the piston over the air intake pipe, a well defined quantity of air under pressure, is a retractable shutter valve for closing the end of said pipe, which has a shape adapted to release said end under the effect of the passage of said piston.
• - Figure 1 is a cross-sectional view AA of the rotary motor;
• - Figure 2 is a diametrical sectional view BB of said motor;
• FIG. 3 is a cross-sectional view AA of the rotary engine comprising two decompression chambers
• FIG. 4 is a principle view of a triangular piston chamber
• FIG. 5 is an abacus giving the pressure received by the piston for an injection of volume 100 times lower than that of the chamber and according to the position of the piston in its stroke;
• FIG. 6 is a principle view of a compressor with triangular compression chamber associated with a motor with rectangular decompression chamber;
• FIG. 7 is an abacus giving, in the case of a triangular compression chamber, the variations of the successive heights of a piston as a function of its position along its stroke.
• the rotary compressed air motor shown in the figures includes:
• V volume chamber delimited, longitudinally, by the cylindrical walls opposite said stator and said rotor and, laterally, by two flanges (3) and (4) facing;
• each decompression chamber (Va) is delimited, longitudinally, at one end, by a wall (7), acting as a piston, integral with the rotor (2) and extending to the stator (1) and, at the other end, by a retractable wall (8), disposed upstream of the corresponding air inlet pipe (5), integral in translation with the stator (1) and extending to the rotor (2), associated to a means adapted to make it retractable during the passage of the piston (7).
• Each air inlet pipe (5) is associated with a means suitable for blowing, into the corresponding decompression chamber (Va), after the passage of the piston (7) over said inlet pipe, a quantity of air under pressure (P) well defined at each rotor revolution.
• the means adapted to move the retractable wall (8) when. of the passage of the piston (7) can be chosen from mechanical cam devices, electromechanical relays and pneumatic cylinders. It can also be the piston (7) itself which has a shape (fig. 1) adapted to disengage said wall during its passage.
• retractable valve (9) for closing the end of said pipe (5), which has a shape adapted to release said end under the effect of the passage of said piston.
• the retractable wall (8) is associated with a means, in particular a spring, adapted to return it to its initial position after the passage of the piston (7).
• the retractable valve (9) is associated with a means, in particular a spring, adapted to return it to its initial position after the passage of the piston (7).
• the piston (7) can be produced by means of an elastic blade bearing on the cylindrical inner wall of the stator (1).
• decompression chambers (Va) each associated with a pressurized air supply line (5), a residual air discharge line (6), a piston (7) and a retractable wall (8), are arranged uniformly distributed
• the decompression chamber (Va) fills with pressurized air as soon as said piston has crossed the inlet pipe (5).
• the volume of said chamber then represents a small part of the volume (V) of the overall circular chamber.
• the residual air (R) is either evacuated into the atmosphere or recycled.
• a turbine dedicated to compressing atmospheric air at room temperature delivers more than 1 Ncm 3 compressed to 5 bars from a motor energy consumption of 1 joule.
• a second contiguous turbine of different size is wedged on the same shaft (for example) drives the first.
• FIG. 5 represents the pressure (P) received by the piston for an injection of 1/100 ee of the volume of the chamber per cycle, therefore the corresponding force as a function of the position (C) of the piston in its course:
• the final pressure is multiplied in proportion to the percentage of the chamber selected.
• the consumption which for 1/100 e of the volume consumed is:
• the engine chamber (Cm) receives, per pulse and per revolution, a percentage of its volume at a selected pressure. It has a rectangular profile. Its exact capacity is calculated since it is a ring profile by subtracting from the total area of the largest circle, the area of the small inner circle.
• the engine part could also be coupled to the compressor part to recover the calories.
• the compressor part must only consist of compression chambers with a triangular profile.
