FIELD: mechanical engineering. SUBSTANCE: in starting and during operation of pneumohydraulic motor, air is fed under pressure to lower inter-blade space of rotor mounted in hermetic rotor section filled with liquid at clearance. Rotor sections are coaxially secured on power take-off shaft for transmission of excessive pressure from accumulator to lower inter-blade space of subsequent rotor sections and to atmosphere from last section after building up the working pressure in rotor section. Continuous supply of air is adequate for creating the torque in each rotor section which sets in rotation power take-off shaft. EFFECT: reduction of energy expenditures. 2 cl |
