Beschreibung
Zusammenfassung:	FIELD: hydraulics, possible use for ensuring operation of extending mast devices on underwater technical means. ^ SUBSTANCE: hydraulic drive contains hydraulic distributor with common hydraulic power system, double-sided action hydraulic cylinder with piston and rod working hollows and blocking valve, input of which is in hydraulic connection with one of working hollows, and output - with consumer, and feeding-draining hydraulic lines. New feature is that working liquid leak selector is installed in form of two-positional hydraulically controlled flow interrupter with lines for controlling closing and opening of working liquid passage. Output of leak selector is connected to drain of common hydraulic power system. Inlet of leak selector and line for controlling closing of working liquid passage are connected by hydraulic lines to output of blocking valve, while line for controlling opening of working liquid passage is connected to rod hollow of hydraulic cylinder. ^ EFFECT: increased reliability of hydraulic drive operation. ^ 2 cl, 1 dwg
