Abstract
A hydraulic damper includes at least one valve assembly () provided with rebound () and compression () valves and at least one resilient deflective disk covering flow channels () of the valve assembly and preloaded by a spring (). The hydraulic damper includes means for clamping together the components of the at least one valve assembly and for preloading the spring. In order to increase the repeatability coefficient among dampers of the same production batch and render it independent on the geometrical tolerances of the valve assembly components, the means have a form of an adjustable nut assembly () comprising a clamp nut () and a shoulder sleeve () fixed on the perimeter of the clamp nut. The clamp nut clamps together the components of the valve assembly and the shoulder sleeve preloads the spring with a predetermined force. method of assembling such a damper.
