Abstract: Device capable of rotating on itself a shaft according to the desired speed of rotation. The invention relates to a device for rotating a shaft without any human input of energy resources. It is made up of: a housing (1) enclosing a turbine (2), a housing (3) enclosing a gear (4), an air compressor unit (5), a compressed air cylinder (6), a cylinder (7) in which a piston (8) is located, a pressure gauge (9) to indicate the pressure in the circuit, a safety and shut-off valve (10), a function valve (11), a safety valve (12) to prevent air leakage at the pressure-gauge (9) side, an air injection valve (13) for a first startup of the device, a safety valve (14) on the valve (13) side to prevent air leakage, pipes (15; 16 and 17) for use as connectors, a free-rotating shaft (26), an air outlet pipe (18), a rotating shaft (19) connected to the air compressor unit (5), a starting lever (20), and an air inlet (21) in the air compressor unit (5). When the air device is filled by the injection valve (13) to be started up, the piston (8) housed in the cylinder (7) is raised to compress the spring (23), which pushes it downwards. If the spring is sufficiently compressed, the air is discharged through an opening (24) which opens onto the valve (11) which is open and the valve (10) which is closed. The pressurised air strikes the blades (25) of the turbine (2) in the housing (1), which starts to rotate and subsequently drives the movement of the piston (22) of the compressor unit (5). The air device is not filled during this time. The circuit is closed, the small amount of air drawn in and injected into the compressed air circuit by the air compressor unit (5) upon each revolution of the piston (22) escapes from the cylinder (7) under pressure through the opening (24). During this time, the cylinder (7) acts as an overflow vessel. The rotational movement is continued until the valve (10) is opened and the valve (11) is closed. The rotational movement transmission shaft (26) must be connected to all of the motors operated by the rotation of a shaft. In order to restart the device, the lever (20) is turned, which lever is easy to assemble and disassemble without being screwed to the housing (1) containing the turbine (2), the valve (10) is closed and the valve (11) is opened. In order to achieve a high turbine rotation speed and tensile force at the shaft (26) and the shaft (19), it must be difficult for the spring (23) to be compressed by the piston (8) of the cylinder (7). Consequently, the screws (29), inter alia, are tightened. Should the turbine complete one revolution, the shafts (19 and 26) must complete several revolutions and the air compressor unit (5) must pump a certain volume of air per revolution of the piston (22). The device according to the invention is particularly intended to automatically rotate a rotating shaft at a desired speed once the air mechanically drawn in by the device from its immediate surroundings has been compressed and can operate anywhere in the universe or in an enclosure containing a non-flammable gas.
