CONTROL DEVICE OF MOVEMENT OF CYLINDRICAL GATE OF HYDRAULIC MACHINE, AND HYDRAULIC MACHINE CONTAINING SUCH DEVICE Russian patent published in 2015 - IPC F03B15/04 F04D15/00 F15B11/22 

FIELD: engines and pumps.

SUBSTANCE: group of inventions can be used in turbines, pumps or turbine pumps. Device (1) controls movement of cylindrical gate (2) of a hydraulic machine between an opening position and a shutting-off position. Device (1) includes at least four hydraulic cylinders (11, 12, 21, 22, 31, 32), stocks (11.3, 12.3) of which have a possibility of being connected to cylindrical gate (2) in places located along perimeter (c2) of cylindrical gate (2). Additionally, device (1) includes at least two hydraulic synchronisation elements (10.1, 20.1, 30.1) of pistons (11.4, 12.4). Synchronisation elements (10.1, 20.1, 30.1) are connected to hydraulic cylinders (11, 12, 21, 22, 31, 32) so that two different groups (10, 20, 30) can be formed. Each group (10, 20, 30) combines at least two hydraulic cylinders (11-12, 21-22, 31-32) connected at least with one synchronisation element (10.1, 20.1, 30.1), with that, two hydraulic cylinders (11, 12, 21, 22, 31, 32) belonging to two different groups (10, 20, 30) are not connected with synchronisation element (10.1, 20.1, 30.1).

EFFECT: inventions are aimed at simplification of adjustments and maintenance operations of the device and creation of a reliable control device, which is easy to adjust.
