HYDRAULIC DAMPER Russian patent published in 2007 - IPC F16F9/14 F16F5/00 

FIELD: mechanical engineering.

SUBSTANCE: hydraulic damper contains cylinder with hollow rod and piston provided with L-shaped channels. Piston is rigidly secured on hollow rod. Two semispherical diaphragms are installed in overpiston zone inside hollow rod, one of which is solid and the other is provided with axial through hole. Spherical solid of revolution is installed for movement in space between diaphragms. Said spherical solid of revolution has round flay in horizontal equatorial area and vertical axial through channel. Channels tilted to longitudinal axis of symmetry are made in walls of hollow rod in space between diaphragms.

EFFECT: simplified design, improved efficiency of operation of hydraulic damper.
