HYDRAULIC ACTUATOR WITH FLEXIBLE ROD Russian patent published in 2009 - IPC F15B15/14 F15B15/20 

FIELD: machine building.

SUBSTANCE: hydraulic actuator is provided for transmission of tractive effort to relocated object. In casing with end cover it is located piston connected to flexible rod with dragging clutch. Compaction unit of flexible rod contains locked cavity with flexible material and sealing element, compressed by piston of cover and pistons of pressure transformer. Hydraulic actuator is outfitted by resilient backbone site including annular bearings connected to resilient members by means of movable bearing bushes installed with ability of shifting in radial direction at caving in of flexible rod and in axial direction at damping of piston or clutch by compaction unit. Resilient members interacting to piston of pressure transducer and movable end cover are matched to cleaning members.

EFFECT: reduction of member's wear higher efficiency, simpler design and pressure transducer.
