The closest to the technical nature of the claimed is a pneumatic-hydraulic Converter of mechanical energy into electrical energy, comprising a housing partially filled with liquid, in which the transfer system is open containers, made in the form placed at different heights on the two shafts with the corresponding elements covered by an endless chain to which is attached an open container and the pneumatic system consisting of a compressor and a duct connecting the lower part of the housing with the compressor (see application Germany N 2408682, CL F 03 B 9/00, op. 1975). In the known Converter open container made in the form of bell-shaped floats, the transmitting elements of the shafts in the form of gears, while the outlet duct arranged laterally from the lower gears, and an electric power generator is directly connected with the shaft of this wheel.

The task of the invention is to improve the operational reliability of the pneumatic-hydraulic Converter of mechanical energy into electrical energy while increasing the efficiency of the Converter.

The solution of the stated problem is provided by a new pneumohydraulic is where the transfer system is open containers, comprising at least two shafts with transmitting elements placed at different heights, at least one endless belt covering transmitting elements shaft, and at least one support element located between the opposite sections of the endless belts, each open vessel has the form of an open cylinder with a spherical bottom and attached to the outer surface of the tape, and on both sides of the system installed tubular supporting elements, which are placed in the open cylinders, pneumatic system, comprising at least from one dispenser compressed gas into the open cylinder valve located under the lower conveying element, a location sensor open cylinder above the dispenser and automatic control unit, connected to the valve and to the sensor, and at least one shaft through the gear - multiplier connected to the electricity generator; preferably: a support element located between the opposite sections of the endless belts, to perform in the form of a parallelepiped, parallel to the surface facing the inner surfaces of the endless belts; between the opposite sections of the infinite is the possibility of rotation and cooperating with the inner surface of an endless belt; the tubular supporting elements to perform in the form of semi-cylinders attached to the inner surface of the housing; an endless belt to run in the form of a set being in mesh moving parts, for example, in the form of a caterpillar tractor or tank; an endless belt to run in the form of an elastic element, while transmitting elements shafts to perform with convex corrugated surfaces, for example, to perform an endless tape in a grid, sformirovannoi in the rubber layer; a location sensor open cylinder above the dispenser to perform in the form of a mechanical chopper, and place together with the dispenser; a pneumatic system to perform multiple dispensers, each of which has a nozzle, when this nozzle to be positioned at different heights in accordance with the path of the open cylinder below the lower conveying element.

In the claimed pneumo-hydraulic Converter is provided, at least one supporting element is located between the opposite sections of an endless belt, and a supporting tubular elements placed on both sides of the moving system of open containers, which are moved open container. This can significantly reduce the mechanical on the since bowing of the tape when exposed to a jet of compressed air, fill the open cylinder is minimized due to the fact that the inner surface of the belt cooperates with a support member, a layer of liquid between them performs the function of lubrication. Similarly reduces the load on the endless tape introduction of the tubular supporting elements mounted on both sides of the moving system, in which in the vertical direction are moved to an open container. The gaps between the tubular support elements and moving them in open cylinders are small (about 1-2 mm), this eliminates the possibility of significant roll of the open cylinder and its impacts on the tape, and the liquid in the gap eliminates the friction between the tubular member and the open cylinders. Preferably the support element to perform in the form of a parallelepiped, is placed between the opposite sections of an endless belt, as this maximally simplifies the design of the support element. Preferably the endless tape is run in the form of a set being in mesh moving parts, for example, in the form of a caterpillar tractor or tank, as this may increase the operational reliability due to duplication of work by Paralia the width of the tape. A similar effect is observed when running the tape in the form of an elastic element, for example, in the form of a mesh, molded in the rubber layer, while transmitting elements shafts have a convex corrugated surface. The implementation of open containers in the form of an open cylinder with spherical bottoms enhances the efficiency of the Converter, as reduced loss due to hydraulic resistance when moving in open containers. Execution of the pneumatic system in the form of at least one dispenser compressed gas into the open cylinder valve connected to the automatic control unit, and the introduction of sensor locations open cylinder above the dispenser, also connected to the automatic control unit, virtually eliminates wasteful consumption of compressed gas, due to the fact that each portion of the compressed gas coming from the dispenser, corresponds to the inner volume of the open cylinder, which, when the valve opening is located above the dispenser. The location sensor open cylinder above the dispenser preferably in the form of a mechanical interrupter, as this maximally simplifies the design of the sensor and increases the value of the open position of the vehicle and thus reduce wasteful consumption of compressed gas. You can use multiple dosing with nozzles, which are mounted at different heights in accordance with the path of the open cylinder below the lower conveying element above the dispensers, which also helps to reduce the unproductive consumption of compressed gas and a corresponding increase in the efficiency of the Converter. The connection of the shaft with a generator of electricity through the gear-multiplier improves the efficiency of the Converter, since getting the desired frequency of the generated current is achieved automatically without the use of additional transducers included between the electricity generator and the consumer.
