A rescue device contains the case filled with the working fluid, the brake mechanism, the roll for spooling the rope, and the rings attached to the ropes. The hydrodynamic sleeve designed as two wheels of the reactive turbine is used as the brake mechanism. Inside the case, between the wheels of the reactive turbine, the centrifugal pump is installed. The latter is connected to the roll and is capable for rotation relative to the immobile wheels of the reactive turbine. |
