Abstract

The elastomer clamping assembly with a valve piston has the advantage over the known double-chamber system that the valve is installed directly in the piston and therefore does not require the double chamber. Due to the valve piston, three forces counteract the entry of the piston rod into the cylinder space. 1. The prestressing force of the compressible elastomer. 2. The prestressed spring. 3. The dynamic pressure on the surface of the valve piston, which is dependent on the speed of the retracting piston rod. On completion of the working stroke of the piston rod, the compressible elastomer expands and extends the piston rod again.

Description

Dieses Patent hat sich zur Aufgabe gestellt, die beiden bisher bekannten Elastomer-Spannpakete nach Patentanmeldung Nr. P 34 04 517.1, bei denen die Vorspannkraft des kompressiblen Elastomers gegen die Fläche der Kolbenstange wirkt und das nach der Patentanmeldung Nr. P 35 08 574.6, wo die Federkraft der Kolbenstange zusätzlich durch ein Zwischen­ kammersystem und einem damit verbundenen vorgespannten Ventil verstärkt wurde, zu vereinfachen.This patent has set itself the task of the two Previously known elastomer clamping packages after patent application P 34 04 517.1, where the preload force of the compressible Elastomer acts against the surface of the piston rod and that after the patent application No. P 35 08 574.6, where the Spring force of the piston rod additionally through an intermediate chamber system and an associated prestressed Valve was reinforced to simplify.

Bei dem Elastomer-Spannpaket mit Ventilkolben wirken drei Elemente als Federkraft gegen die Kolbenstange.There are three in the elastomer clamping package with valve piston Elements as spring force against the piston rod.

  • 1. Das vorgespannte kompressible Elastomer 11, welches sich im Innenraum des Zylinders 12 befindet und dessen Vorspanndruck gegen die Fläche der Kolbenstange 1 wirksam ist.1. The prestressed compressible elastomer 11 , which is located in the interior of the cylinder 12 and whose prestressing pressure is effective against the surface of the piston rod 1 .
  • 2. Die Vorspannung der Feder 6, welche durch die Stellschraube 7 entsprechend vorgespannt wird und beim Einfahren der Kolbenstange 1 das Elastomer 11 durch die Bohrung 13 des Ventilkolbens 3 drückt und somit den Widerstand der Feder 5 überwinden muß.2. The bias of the spring 6 , which is biased accordingly by the adjusting screw 7 and pushes the elastomer 11 through the bore 13 of the valve piston 3 when retracting the piston rod 1 and must therefore overcome the resistance of the spring 5 .
  • 3. Die Verdrängungskraft, die beim Einfahren der Kolben­ stange 1 gegen die Fläche des Ventilkolbens 3 entsteht.3. The displacement force, the rod 1 is created against the surface of the valve piston 3 when retracting the piston.

Durch das Zusammenwirken dieser drei beim Einfedern der Kolbenstange wirksam werdenden Kräfte wird die Federkraft gegenüber der Vorspannkraft des kompressiblen Elastomers in Verbindung mit der einfedernden Geschwindigkeit der Kolbenstange 1 erheblich erhöht.The interaction of these three forces, which become effective when the piston rod is deflected, considerably increases the spring force compared to the preloading force of the compressible elastomer in connection with the spring speed of the piston rod 1 .

Beim Ausfahren der Kolbenstange 1 wird die Kraft und die Rücklaufgeschwindigkeit erheblich vermindert, weil nur die Entspannungskraft des komprimierten Elastomers gegen die Fläche der Kolbenstange wirksam wird. Die Rücklauf­ geschwindigkeit wird verringert, weil das zähflüssige Elastomer durch einen kleinen Schlitz der Kolbendichtung 4 zurückfließen muß.When the piston rod 1 is extended, the force and the return speed are considerably reduced because only the relaxation force of the compressed elastomer acts against the surface of the piston rod. The return speed is reduced because the viscous elastomer must flow back through a small slot in the piston seal 4 .

Claims (3)

1. Elastomer-Spannpaket dadurch gekennzeichnet, daß die Kolbenstange 1, welche im Kolbenlager 2 gelagert ist, einen Ventilkolben 3 besitzt, welcher mit der Mutter 6 gegen die Tellerfeder 5 vorgespannt ist und somit den Durchfluß des Elastomers 9 durch die Bohrungen 10 bremst, weil der Durchfluß des Elastomer 9 zwischen dem Ventilkolben 3 und der Zylinderwand 11 durch die Dichtung 4 verhindert wird.1. Elastomer clamping package characterized in that the piston rod 1 , which is mounted in the piston bearing 2 , has a valve piston 3 , which is biased with the nut 6 against the plate spring 5 and thus brakes the flow of the elastomer 9 through the holes 10 because the flow of the elastomer 9 between the valve piston 3 and the cylinder wall 11 through the seal 4 is prevented. 2. Elastomer-Spannpaket nach Anspruch 1 dadurch gekennzeichnet, daß mittels der Mutter 6 die Vorspannung der Tellerfeder 5 verändert werden kann.2. Elastomer clamping package according to claim 1, characterized in that the bias of the plate spring 5 can be changed by means of the nut 6 . 3. Elastomer-Spannpaket nach Anspruch 1+2 dadurch gekenn­ zeichnet, daß in Kolbenlager 2 eine Ventilkugel 7 vorhanden ist und daß diese Ventilkugel durch die Verschlußschraube 8 abgedeckt wird.3. Elastomer clamping package according to claim 1 + 2 characterized in that a valve ball 7 is present in the piston bearing 2 and that this valve ball is covered by the screw 8 .
