Claimed device, a vessel, comprises the first open/close valve arranged at first channel to connect the chamber from rod side with chamber from the piston side. Said chambers are defined by the piston that can open and shutoff the first channel. The second open/close valve arranged in the first channel communicating the chamber from the side of piston with vessel to open and shutoff the second channel. The pump is designed to be actuated at predefined rpm to feed fluid from said tank to the chamber on rod side. The pump rpm is decreased at the force set by the signal lower than the normal limiting lower magnitude. The latter makes the lower limiting magnitude of the force to be generated by the drive at the pump revolution at normal rpm. |

Invention relates to wind power engineering, particularly, to windmills. Windmill comprises the base with two vertical rotors, cowl and fin to turn in horizontal plane. Said base is provided with horizontal plane directed parallel with the flow and arranged between vertical rotors. The plate is provided with upstream vertical post arranged between vertical rotors and third vertical post located at the downstream end of the plate. Second plate is equipped with horizontal plates mounted at top and bottom of the post perpendicular to the flow. Fin web is arranged between the second and third posts. Cowl web is stretched between the ends of second post plates and envelops the first plate. |

Invention can be used in turbopump units of liquid-propellant rocket engines incorporated with multiple-shot rockets. Invention aims at increasing the turbopump bearing serviceability at multiple burns of liquid-propellant engine by decreasing the bearing heating. For this, claimed turbopump unit comprises housing 1, rotor with rotary pump 2, turbine 3, bearing support 4, low-pressure pump intake pump 5, high-pressure pump outlet 6, high-pressure chamber 7, pipe 8, check valve 9 and jet 10. At engine shutdown, the pressure downstream of the pump drops to zero. Note here that check valve 9 closes to force the liquid component from high-pressure chamber 7 via jet 10 by fuel component vapour pressure into bearing support to cool down the bearings. |

Method of hydrogen accumulation in lamellar electrodes Reservoir for hydrogen storage represents a regular nickel-cadmium accumulator with lamellar electrodes. The proposed hydrogen accumulation method consists in saturation of electrodes with hydrogen by means of its diffusion inside electrodes. Electrodes are saturated with hydrogen, due to electrolysis of electrolyte during accumulator recharge under voltage of 1.7 V for 1.8 years. |

Method of aircraft engine augmentation Operation of gas turbine engine with augmentation chamber consists in the making of fuel-air mix to be combusted in the main combustion chamber. Combustion products are expanded in the turbine and fed into the augmenter wherein combustion products are mixed with augmentation fuel. Said augmentation fuel is composed of aluminium nanoparticles, their radius not exceeding 25 nm. Water vapours and carbon dioxide contained in the main combustion chamber products are used as the oxidizer for augmentation fuel. |

Valves for urea injection system Device comprises a chamber configured to receive a compressed gas through the first inlet, obtaining the urea solution through the second inlet, and supplying the combined flow of compressed gas and urea to the outlet, the flow channel extending from the first inlet to the placement surface, and a valve element made movable between the open position in which the valve element is spaced from the placement surface, and a closed position in which the valve element contacts the placement surface. When moving the valve element from the open position to the closed position of the valve element contacts the placement surface at the first point and wipes the placement surface area extending from the first point in the direction of the flow channel. The method and the system of dispensing for subsequent treatment of exhaust gases are also disclosed. |
