Abstract:
The invention concerns a method of control of a damping force of a hydraulic damper, which comprises a housing filled with a fluid, inside which a piston connected to a piston rod is guided axially, whereas spaces above and under the piston are connected through connecting channels in which fluid flow rate control members are arranged, the subject matter of which lies in a fact that the damper piston velocity is determined at which a connecting hole between the spaces above and under the piston opens, is kept open at a velocity above the determined piston velocity value and after the piston velocity drops below the determined value, the connecting hole closes. A subject matter of a hydraulic damper, which comprises a housing filled with a fluid, inside which a piston connected to a piston rod is guided axially, whereas the spaces above and under the piston are connected through connecting channels in which fluid flow rate control members are arranged, lies in a fact that piston rod (3) of the damper is connected to a control member for opening of connecting hole (7) between the spaces above piston (2) and under piston (2) of the damper.

Abstract:
Schwingungsdämpfer mit hydraulischem Zuganschlag Ein Schwingungsdämpfer mit hydraulischem Zuganschlag für eine Kraftfahrzeugradaufhängung umfasst ein Behälterrohr (2'''), eine Kolbenstange (3''') und eine hydraulische Dämpfungseinrichtung (10''') mit einem an der Kolbenstange (3) befestigten Dämpfungskolben (11'''), welche in einem Endbereich eines Kolbenstangenauszugswegs vor Erreichen des maximalen Kolbenstangenauszugswegs eine der Zugbewegung der Kolbenstange (3''') entgegen gerichtete hydraulische Kraft bereitstellt. Der Dämpfungskolben (11''') weist eine umlaufende Nut (12''') auf, in der ein geschlitzter Dichtungsring (16''') aufgenommen ist, welcher in besagtem Endbereich des Kolbenstangenauszugswegs bei Bewegung der Kolbenstange (3''') in Zugrichtung in der Nut (12''') hydraulisch abdichtet und bei Bewegung der Kolbenstange (3''') in Druckrichtung von einer druckrichtungsseitigen Flanke (14''') der Nut (12'''), welche die Nut (12''') auf der Seite in Druckrichtung begrenzt und in Zugrichtung weist, zumindest lokal abhebt, um eine definierte Durchlässigkeit für ein hydraulisches Dämpfungsmedium zwischen der Nut (12''') und dem Dichtungsring (16''') hindurch bereitzustellen.

Abstract:
An end member assembly can include a first end member section and a second end member section that together form an end member volume. A partition section is provided separately and is disposed within the end member volume to separate the end member volume into at least two volume portions. At least one passage extends through the partition section and at least one control device is disposed in fluid communication along the passage. The control device substantially fluidically isolates the two volume portions under conditions of use below a predetermined differential pressure threshold. The control device permits fluid communication between the two volume portions under conditions of use in which the predetermined pressure threshold is exceeded. Gas spring assemblies including such an end member assembly as well as suspension systems and methods of manufacture are also included.
