LIMITED SLEWING LOCINIATE HYDRAULIC DRIVE Russian patent published in 2009 - IPC F15B15/12 

FIELD: machine building.

SUBSTANCE: device is provided for usage in machine building in the capacity of drive for rotation of execute part of mechanism. On fixed spindle fixed in basis it is installed cylindrical casing with ability of rotation with formation of working cavity. Working cavity allows toroidal shape. On rotary casing and on fixed shaft there are implemented two by two blades, installed diametrically opposite in working cavity. Blades allows in longitudinal section oval shape. Inside the shaft there are implemented channels of pressure and discharge of working fluid with parallel branching, connected to working cavity. In bottom basis and in bottom part of casing there are implemented interacting bearings, limiting rotation of casing. On top basis it is installed contact signalling device spring loaded pusher of which is installed with ability of interaction to guide block fixed on casing. On rotary casing it is installed toothed sector for passing of rotational moment to the consumer. Sealing elements between casing and shaft and also seals of blades are implemented in the form of standard sealing rings.

EFFECT: device provides at small dimensions transferring of significant rotational moment and of necessary implementation of rotation of executing mechanism for rigorously defined angle.
