FLUID PRESSURE-POWER MOTOR Russian patent published in 1998 - IPC

FIELD: self-contained motors for power engineering. SUBSTANCE: motor frame is divided into two parts. One part houses hydraulic turbine and other part incorporates fluid acceleration cylinders and cylinder operating mechanism. Hydraulic turbine has hollow rotor with axial entrance and two nozzle assemblies with peripheral nozzles, as well as blades. Nozzles of one assembly are positioned in opposite direction relative to those of other assembly to organize reversal of output shaft. Blades are used to afford residual kinematic energy of fluid jet downstream of nozzle assembly. Fluid flow transfer from one nozzle assembly to other is provided by special switch. Cylinder operating mechanism provides for sequential connection of cylinders to axial entrance of hollow rotor. Frame communicates through pipelines and pressure-reducing valve with air vessel feeding compressed gas pressure to motor. EFFECT: improved design. 2 cl, 3 dwg
