Hydraulic damper, particularly passive compensation unit for decreasing attenuation entering due to temperature increase of hydraulic mediums, has throttle through which hydraulic medium flows, and flow cross-sectional of throttle is varied

摘要

The hydraulic damper has a throttle (1) through which a hydraulic medium (2) flows. The flow cross-sectional (4) of the throttle is varied. A passive compensation device is provided for a discharging of a damping of the damper, entering as a result of a rise in temperature of the hydraulic medium. The damper continuously narrows the flow cross section of the throttle in a partial range of a working temperature range of the damper over a material (5) delimited with a temperature increase corresponding thermal expansion of the flow cross section.
