SYNCHRONOUSLY CONTROLLED HYDRAULIC SYSTEM Russian patent published in 2001 - IPC

FIELD: mechanical engineering; mobile machines converted for hydraulic operation. SUBSTANCE: proposed hydraulic system with synchronous control has variable-capacity hydraulic pump with control hydraulic distributor sensitive to load, working liquid tank and safety valves in power hydraulic line. Each section of hydraulic system has main hydraulic distributor, and two-position two-line comparing distributor. Comparing hydraulic distributor is normally closed and connected at one side with control line of main hydraulic distributor and at other side, with tank. Pressure from working tap is supplied to end face of comparing hydraulic distributor from one side, and from load-sensitive line, to end face of side. Signal from working taps to load-sensitive line passes through check valve. Restrictor is installed in main hydraulic distributor control line before point of connection of comparing hydraulic distributor. EFFECT: simplified hydraulic system of mobile machines with synchronous control. 2 cl, 1 dwg
