Abstract

Offenbart ist ein hydraulischer Rotationsdämpfer (1) mit einem Gehäuse (2) in dem ein Rotationskolben (4) geführt ist, wobei das Gehäuse (2) zum Rotationskolben (4) hin vorstehende Stege (62, 64) hat, die gemeinsam mit dem Rotationskolben (4) Druckräume begrenzen, und wobei am Rotationskolben (4) Radialvorsprünge (28, 30) ausgebildet sind, die die Druckräume jeweils in zwei Teilräume (66, 68) teilen, deren Volumen sich mit dem Drehwinkel des Rotationskolbens (4) ändert, wobei zwischen den Teilräumen (66, 68) steuerbare Drosselquerschnitte ausgebildet sind, die ein Überströmen von Druckmittel von dem sich verkleinernden Teilraum zu dem benachbarten, sich vergrößernden Teilraum ermöglichen, wobei sich in zumindest einer Drehrichtung ein Drosselquerschnitt sprunghaft verringert oder vergrößert, wobei zumindest ein steuerbarer Drosselquerschnitt durch eine Tasche (98) begrenzt ist, deren Wirkquerschnitt in der Drehrichtung verringert ist. Erfindungsgemäß hat die Tasche (98) eine Rampe (99), durch die der Drosselquerschnitt in Drehrichtung stufenförmig verringert ist, wobei eine Höhe (H) der Rampe (99) größer ist als die Tiefe (t) einer durch die Rampe (99) ausgebildeten Turbulenzkammer (101) der Tasche (98).Disclosed is a hydraulic rotary damper (1) with a housing (2) in which a rotary piston (4) is guided, the housing (2) having webs (62, 64) protruding towards the rotary piston (4) which, together with the rotary piston (4) delimit pressure chambers, and wherein radial projections (28, 30) are formed on the rotary piston (4), which divide the pressure chambers into two sub-chambers (66, 68), the volume of which changes with the angle of rotation of the rotary piston (4), wherein between the partial chambers (66, 68) controllable throttle cross sections are formed, which allow pressure medium to flow from the decreasing partial chamber to the adjacent, increasing partial chamber, with a throttle cross section suddenly decreasing or increasing in at least one direction of rotation, with at least one controllable throttle cross section is delimited by a pocket (98) whose effective cross-section is reduced in the direction of rotation. According to the invention, the pocket (98) has a ramp (99) through which the throttle cross section is reduced stepwise in the direction of rotation, with a height (H) of the ramp (99) being greater than the depth (t) of a ramp (99) formed turbulence chamber (101) of pocket (98).
