Bodenventil für hydraulische Teleskopstoßdämpfer.Bottom valve for hydraulic telescopic shock absorbers.

Die feuerung betrifft «in Bodenventil für hydraulische !Eeleskopstoßdämpfer mit einem fien Arbeitszylinder •umgebenden ringf örmgen Yorratsraum, der über das Bodenventil aalt «iner Druckkammer in Verbindung steht·The firing concerns «in the bottom valve for hydraulic ! Telescopic shock absorber with a fien working cylinder • Surrounding annular storage room, which is accessible via the bottom valve is in communication in the pressure chamber

Bei Stoßdämpfern aait einem derartigen Bodenventil ergibt sieh der Nachteil, daß "bei ständig offenem Durchgang -der Terbindung zwischen der Druekkaismer und dem Tor— rstsraum die DrucMcammer wänrend des Euhesustandes des StoBdämpfers allmählich durch Abfließen der DämpfungsflüsBigfeeit an Inhalt verliert, so daß heim Gegenhub leicht Jlüssigkeitsschlage auftreten können.In shock absorbers aait such a bottom valve see the disadvantage that "with the passage open all the time -the connection between the Druekkaismer and the gate- the pressure chamber during the euhesustandes of the Shock absorber gradually by draining the damping fluid loses its content, so that home counter stroke Liquid shocks can easily occur.

Die !feuerung sieht daher vor, daß außer dem in bekannter leise mit ständigen Durchgangs Öffnungen versehenen als einseitig wirkendes KLattenventil ausgebildeten Hauptventil ein Zusatsplattenventil angeordnet ist, das den Yerfrindungskanal von £er Druckkammer zum Hauptventil derart abschließt, daß die Druckkammer gefüllt ,gehalten und ein Abfließen xLex Dämpfungsflüssigkeit aus der Druckhammer bei nicht abgehobener Yentilplatte verhindert "wird*The fire therefore provides that, in addition to the main valve, which is quietly provided with constant passage openings and designed as a unilaterally acting disc valve, an additional plate valve is arranged which closes the branching duct from the pressure chamber to the main valve in such a way that the pressure chamber is filled, held and drained xLex damping fluid from the print hammer if the Yentil plate is not lifted "is prevented *

Diese Ausbildungsform hat außerdem den Torteil, daß das Hauptventil weicher anspricht, da bei plötzlichen -Riehtungsänderungen der Stöße zunächst das Susatzventil abhebt und =erst bei stärkerem Druckanstieg das Hauptven— til in !Tätigkeit tritt. Das Zusatzventil ist also vor allem leicht druckabhängig,, das Hauptventil dagegen druck— geschwindigkeitsabhängig*This embodiment also has the Torteil that the main valve softer appeals because in case of sudden surges of -Riehtungsänderungen initially lifts the Susatzventil and = only with stronger pressure increase in the main valve! Activity occurs. The additional valve is therefore primarily slightly pressure-dependent, the main valve, on the other hand, is pressure-dependent on speed *
