DAMPER'S BEARING STRUCTURE Russian patent published in 2009 - IPC F15B15/14 F16J1/02 F16F9/32 F16F9/58 

FIELD: machine building.

SUBSTANCE: invention relates to bearing structure of damper in hydraulic actuator. Structure for fixation of damper (72a, 72b) is located in hydraulic actuator. Coats (14, 16) are installed on of the cylinder (12) casing. Piston (18,) is installed inside the cylinder (12) casing. Damper groove (70a, 70b) contains the first and the second grooves. The first groove (74) is open from the side of end surface. The second groove (76) is located adjoining to the first groove (74) and expands relative to it. According to the first version damper groove (70a, 70b) is formed on the end surface of piston (18) perpendicularly to its axis and is directed to covers (14, 16). According to the second version damper groove is formed on the end surface of cover (14, 16) perpendicularly to its axis and is directed to piston (18). Damper (72a, 72b) contains basic element (80) and expanding relative to its guideline element (82).

EFFECT: creation of structure providing easy and reliably install damper on piston or covers.
