MULTI-FUNCTIONAL HYDRAULIC SYSTEM Russian patent published in 2006 - IPC F16H39/02 F15B15/02 F16D31/02 

FIELD: hydraulics.

SUBSTANCE: multi-functional hydraulic system comprises controlled pump (1), main pipelines (2) and (3), single-rod hydraulic cylinders (4) and (5), hydraulic motor (6), and auxiliary pump (7). Pressure pipeline (8) of pump (7) is connected with safety valve (9) and make-up valves (10) and (11). The outlet of make-up valve (10) is connected with working pipeline (3), and the outlet of make-up valve (11) is connected with working pipeline (2). Hydraulic distributor (12) is connected with the pressure pipeline (8). The output of the hydraulic distributor is connected with drain space of make-up valve (10) through pipeline (13). The drain space is in communication with tank (14). The working spaces of hydraulic cylinders (4) and (5) and hydraulic motor (6) are connected with pipelines (2) and (3) through hydraulic distributors (15), (16), and (17), respectively. The under-piston spaces of hydraulic cylinders (4) and (5) are connected with pipeline (3), and above-piston spaces of them are connected with pipeline (2).

EFFECT: simplified structure and enhanced stability of operation.
