HYDRAULIC DAMPER Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: hydraulic damper comprises piston provided with axial passages and working cylinder filled with fluid. The piston is connected with the rod. The inner side of the cylinder and outer side of the cylinder, which is in a contact with the piston side, are provided with thread. The piston is mounted on the rod for permitting rotation around the rod. The piston is provided with radial passages whose longitudinal axes intersect with the longitudinal axes of the axial passages of the piston. The diameters of the axial passages decrease from the longitudinal axis of symmetry of the piston to its periphery. The radial passages receive movable spring-loaded slide valves whose diameters exceed these of axial passages of the piston.

EFFECT: expanded functional capabilities.
