Vorrichtung zum Einstellen des Steuerdruckes bei hydraulisch, betätigten Bremsventilen.Device for adjusting the control pressure when hydraulically operated Brake valves.
Die Neuerung betrifft eine Vorrichtung zum stufenweisen Einstellen des Steuerdruckes bei hydraulisch betätigten Bremsventilen mit einem federbelasteten Ventilkörper.The innovation relates to a device for stepwise Adjustment of the control pressure for hydraulically operated brake valves with a spring-loaded valve body.
Hydraulische Bremsventile werden fm Rücklau* von Hydraulikkreisläufen angeordnet, um eine Last kontrolliert absenken zu können. Um unterschiedliche Verateilkräfte zu erhalten, ist eine aufwendige mechanische Verstellung der Ventilfedervorspannkraft erforderlich.Hydraulic brake valves are arranged fm return of candidat * of hydraulic circuits, to be able to lower controlled to a load. In order to obtain different distribution forces, a complex mechanical adjustment of the valve spring pretensioning force is necessary.
Um diesen Mangel zu beseitigen und in einfacher Weise den Steuerdruck von Bremsventilen stufenweise einstellen zu können, ist nach der Neuerung vorgesehen, dass dem Yentilkörper mindestens ein Steuerkolben mechanisch vorgeschaltet ist und Ventilkör~>er und Steuerkolben eine axiale Durchbohrung aufweisen, von denen jeweils eine mit einem Verschluss abachliessbar ist. Die axialen DurchbohrungenIn order to eliminate this deficiency and in a simple way To be able to adjust the control pressure of brake valves in stages, the innovation provides that the valve body at least one control piston is mechanically connected upstream and the valve body and control piston have an axial through-hole have, one of which can be closed off with a lock. The axial perforations

können wahlweise verschlossen werden. Auf diese Weise wird es möglich, den Steuerdruck je nach Anordnung bei einer axialen Durchbohrung wahlweise auf unterschiedliche Kolbenflächen wirken zu lassen, wodurch bei gleichen Verstellkräften unterschiedliche Steuerdrücke wirksam werden. Eine aufwendige mechanische Verstellung der Ventilfedervorspann kraft Kann bei dieser Anordnung entfallen.can optionally be locked. In this way it is possible to adjust the control pressure depending on the arrangement at a to allow axial through-hole to act optionally on different piston surfaces, whereby the same adjustment forces different control pressures take effect. A complex mechanical adjustment of the valve spring preload force Can be omitted with this arrangement.
