Kolben für hydraulische geräte, insbesondere hydraulisehe SchwingungsdämpferPistons for hydraulic devices, in particular hydraulic vibration dampers

Die !Teuerung betrifft einen Kolben für hydraulische Geräte, insbesondere hydraulische Schwingungsdämpfer, gekennzeichnet dadurch, daß ein an sich bekanntes federbelastetes Zwischenglied nach der einen Strömungsrichtung hin als Ventil für den Sitz im Kolben und nach der anderen Strömungsrichtung hin als Ventilsitz für die Ventilscheibe bzw. Ventilscheiben, die gleichzeitig die Federbelastung für das Zwischenglied darstellen, ausgebildet ist.The! Price increase concerns a piston for hydraulic devices, in particular hydraulic vibration dampers, characterized in that a known per se Spring-loaded intermediate member in one direction of flow as a valve for the seat in the piston and after the other direction of flow as a valve seat for the valve disk or valve disks, which at the same time represent the spring loading for the intermediate member is formed.

Durch diese Ausbildung des Kolbens für insbesondere hydraulische Schwingungsdämpfer wird eine universellere Anwendungsmöglichkeit sichergestellt, da die Ausbildung erlaubt, daß die Ventilstellungen, die in bekannter Weise durch eine Vorspannmutter eingestellt werden, unabhängig voneinander sind und durch die Vorspannung der Ventilsoheibe bzw. der Ventilscheiben bestimmt werden.This design of the piston for hydraulic vibration dampers in particular makes it more universal Application possibility ensured, since the training allows that the valve positions, which in known Way can be adjusted by a preload nut, are independent of each other and by the preload the valve plate or the valve disks can be determined.

Die Zeichnung zeigt den Schwingungsdämpferkolben in beispielsweiser Ausführung im Schnitt,, Der Kolben 1 besitzt mindestens einen Durchgang 2. Der Sitz 3 im Kolben 1 wird mit einem als Ventil wirkenden Zwischenstück 4 abgedeckt, das mindestens einen Vordrosselquerschnitt 5 aufweist.The drawing shows the vibration damper piston in an exemplary embodiment in section, the piston 1 has at least one passage 2. The seat 3 in the piston 1 is provided with an intermediate piece that acts as a valve 4 covered, which has at least one choke cross section 5.

Auf dem Zwischenstück 4 liegen eine oder mehrere Federseheiben 7 auf, die vermittels einer Mutter 6 vorgespannt werden. Die entgegengerichtete Federscheibe bzw. mehrere entgegengerichtete vorgespannte Federscheiben 8 dienen gleichzeitig als Ventil für das Zwischenstück 4. Die Ausbildung ist in der Weise erfolgt, daß der Sitz 3 des Ventils und die Ventilausbildung des Zwischenstückes 4 in einer Ebene liegen.One or more spring washers 7, which are pretensioned by means of a nut 6, rest on the intermediate piece 4 will. The oppositely directed spring washer or several oppositely directed preloaded spring washers 8 are used at the same time as a valve for the intermediate piece 4. The training is carried out in such a way that the seat 3 of the valve and the valve configuration of the intermediate piece 4 lie in one plane.
