(57) Abstract:The engine is designed to convert the energy of compressed air into mechanical energy. The device comprises a fluid-filled tank. In the upper and lower parts of the containers placed drive wheels covered in endless working body. On the last fixed bell-shaped floats. To the bottom of the tank connected to a source of compressed gas with the gas filling the internal cavity of each float. The floats are on the side of the nozzle directed at an angle to the vertical axis. The nozzles are located above the balance jumper in the role of a shutter, the lower part of the jumper is made at the level of the lower edge of the float and the upper level of the lower part of the nozzle. The design allows the engine to increase its efficiency. 2 Il. The invention relates to energy and can be used to provide consumers with the energy stored in the water and the air.Already known to the pneumatic piston type, containing a cylinder and a piston, in which the heat accumulated in the air, not used, which reduces the efficiency of the engine.There is also known a pneumatic turbine type containing gas is x2">Known pneumatic engine /see RF patent N 2003830/ adopted for the prototype, containing a water-filled enclosure holds a working body, representing the endless chain mounted on it bell-shaped floats and interacting with a generator of electric energy. The prototype takes away heat accumulated in the water and the air, turning it into mechanical work, but occurs when the displacement of water from the float compressed air directed down and acting on the lower float reactive power reduces the efficiency of the engine.The objective of the invention is to increase the efficiency of the engine by changing the direction of the reactive force caused by the displacement of water from the float compressed air.In Fig. 1 depicts pneumohydrodevices, and Fig. 2 - his float. Pneumohydrodevices includes a source of compressed air is connected by a pipe 1 with a bell-shaped floats 2, hinged to the circuits 3, interacting with the toothed wheels 4 and placed into the body of water 5. The floats are on the side facing the inside of the housing, the nozzle 6 above balance jumper 7 in the lower part of the float, at the same time acting as a shutter.Vozduha floats to surface. Occurs when the displacement of water reactive force directed at an angle to the force of buoyancy, directed vertically upwards. Water outlet through the lower part of the float and downward will not, because the water pressure at the lower edge of the float is greater than the water pressure at the level of the upper part of the balance jumper 7, the weight change of which the clamp float to the wall of the housing 5. When the pressure change as the ascent is the heat from the water of the expanding air in the quantity selected in compression. Thus, in addition to the force of buoyancy is used by the reactive force of the displaced water, increasing the efficiency of pneumohydrodevices.Technical and economic efficiency is expressed in removing virtually inexhaustible source of energy, readily available and environmentally friendly, as the energy stored in water and air. Energosberegaushie pneumohydrodevices containing fluid-filled container placed on the top and bottom parts of the drive wheels, covered endless working body, bell-shaped floats, mounted on the working body, and a source of compressed gas connected to the vessel in its lower part with the possibility of filling is about the floats are on the side oriented at an angle to the vertical axis of the nozzle, above balance jumper in the role of a shutter, the lower part of which is maintained at the level of the lower edge of the float and the upper level of the lower part of the nozzle.
