FIELD: mechanical engineering. ^ SUBSTANCE: rotatable damper comprises housing provided with intake, rotor which is mounted in the intake for rotation and is locked against movement in axial direction, piston which is inserted in the intake between the rotor and bottom of the intake for permitting movement in the axial direction, is locked against rotation, and divides the inner space of the intake into the first chamber near the bottom and the second chamber near the rotor, viscid fluid which fills the first and second chambers, and cam mechanism interposed between the rotor and piston. The cam mechanism allows the piston to move from the second chamber to the first chamber when the rotor rotates in one direction and from the first chamber to the second chamber when the rotor rotates in the opposite direction. The first chamber receives the cam member which is unmovable in the axial direction of the intake and can rotate. The second cam mechanism is interposed between the cam member and piston and causes the piston to move from the second chamber to the first chamber when rotor rotates in one direction and from the first chamber to the second chamber when rotor rotates in opposite direction. ^ EFFECT: improved functional capabilities. ^ 8 cl, 10 dwg |
