OIL-DISTRIBUTION DEVICE OF ADJUSTABLE-BLADE HYDRAULIC MACHINE

摘要

The invention relates to hydro-turbine construction and allows to increase the reliability of the hydraulic machines. Coaxial rods (CS) 5 and 6 are installed between the oil receiver 1 and the servo motor (CM) 2 inside the shaft 3 of the hydraulic machine and are connected to a plug 11 placed in the annular gap 4. The channels 15 of the caps communicate a cavity 7 between CSH 5 and 6 with the over-piston cavity 9 CM 2. The piston rod 12 of the piston 13 CM 2 is partially placed in the cavity 8 of the inner rod 6 and connected to the feedback link 14. When the oil enters KS 5 and 6 in the cavity 9 and 10 CM 2, the piston 13 moves. 6 make only a rotational movement relative to the sealing sleeves oil riem- nickname that reduces wear. 1 il.
