Abstract
Fluid-Steuerventilsystem fur eine Pumpensteuerung, mit einem von einer translatorisch beweglichen Kolbenstange (3) der Pumpe betatigbaren Steuerventilschieber (12), der zwischen zwei Extrempositionen verschiebbar ist, jedoch auch Zwischenpositionen zwischen den Extrempositionen einnehmen kann, dadurch gekennzeichnet, dass das Steuerventilsystem einen unter Andruckkraft stehenden Stempelkolben (20) umfasst, der in ein mit dem Steuerventilschieber (12) verbundenes Schritt-Rastfeld eingreift.Fluid control valve system for a pump control, with a control valve slide (12) which can be actuated by a translatory piston rod (3) of the pump and which can be displaced between two extreme positions, but can also take intermediate positions between the extreme positions, characterized in that the control valve system operates under pressure standing plunger (20) which engages in a step locking field connected to the control valve spool (12).
Description
Die Erfindung betrifft ein Fluid-Steuerventilsystem fur eine Pumpensteuerung, mit einem von einer translatorisch beweglichen Kolbenstange der Pumpe betätigbaren Steuerventilschieber, der zwischen zwei Extrempositionen verschiebbar ist, jedoch auch Zwischenpositionen zwischen den Extrempositionen einnehmen kann.The invention relates to a fluid control valve system for a pump control, comprising a controllable from a translationally movable piston rod of the pump control valve spool, which is displaceable between two extreme positions, but can also assume intermediate positions between the extreme positions.
Erfahrungsgemaß ist nachteilig, dass ein erneutes Anfahren der Pumpe bei Zwischenstellung des Steuerventilschiebers zwischen den Extrempositionen nicht ohne weiteres moglich ist, da der Fluidstrom, vorzugsweise ein Druckluftstrom, nicht definiert in einen durch die Stellung der Kolbenstange eingestellten Arbeitsraum nur zu einer Seite der Kolbenstange einfuhrbar ist.Experience has shown that it is disadvantageous that a renewed start-up of the pump at the intermediate position of the control valve slide between the extreme positions is not readily possible, since the fluid flow, preferably a compressed air flow, not defined in a set by the position of the piston rod working space is einfuhrbar only to one side of the piston rod ,
Es stellt sich die Aufgabe, den Steuerventilschieber jeweils auch bei Abstellen der Pumpe in eine Ruheposition einfahren zu lassen, so dass ein Anfahren der Pumpe lediglich durch erneutes Anfahren des Steuerfluidstroms, vorzugsweise Luftstroms, möglich ist.It raises the task of the control valve slide in each case to shut down when stopping the pump in a rest position, so that a start of the pump only by renewed start of the control fluid flow, preferably air flow, is possible.
Diese Aufgabe wird mit einem Steuerventilsystem der eingangs genannten Art gelöst, das einen unter Andruckkraft stehenden Stempelkolben umfasst, der in ein mit dem Steuerventilschieber verbundenes Schritt-Rastfeld eingreift.This object is achieved with a control valve system of the type mentioned, which comprises a standing under pressure piston piston, which engages in a connected to the control valve spool step detent.
Dabei ist das Rastfeld so eingestellt, dass immer nur inkrementale Abstande vom Steuerventilschieber in Bezug auf die Ventilöffnungen für den Fluidstrom vorgenommen werden, wobei vorzugsweise die Einstellung des Rastfeldes so ist, dass ein Sprung in eine der Endstellungen vorgenommen wird.In this case, the detent field is set so that only incremental distances are always made by the control valve spool with respect to the valve openings for the fluid flow, wherein preferably the setting of the detent field is such that a jump is made in one of the end positions.
Als vorzugsweise Ausführungsform wird ein Schritt-Rastfeld aus einem Sägezahnkamm am Fuß des Stempelkolbens und einer entsprechenden Sagezahnstruktur am Steuerventilschieber bestehend vorgeschlagen, die ineinander greifen und deren Sägezahnspitzen gerundet sind, so dass sich ein Verharren von Kolbenstange und Steuerventilschieber zueinander nur bei eingerücktem Sägezahnkamm des Stempelkolbens in die Sägezahnstruktur am Steuerventilschieber einstellt.As a preferred embodiment, a step detent of a sawtooth comb at the foot of the plunger and a corresponding sawtooth structure on the control valve slide is proposed, which interlock and whose sawtooth tips are rounded, so that a persistence of piston rod and control valve to each other only with engaged Sägezahnkamm the plunger in Sets the sawtooth structure on the control valve spool.
Alternativ kann das Schritt-Rastfeld aus unterschiedlich magnetisierten Bereichen am Fuß des Stempelkolben und einer entsprechenden Magnetisierungsstruktur am Steuerventilschieber besteht, so dass sich ein Verharren von Kolbenstange und Steuerventilschieber zueinander nur bei Gegenüberstellung gegengepolter Magnetbereiche am Stempelkolbens und Steuerventilschieber einstellt.Alternatively, the step-detent field consists of differently magnetized areas at the foot of the plunger and a corresponding magnetization structure on the control valve spool, so that a persistence of piston rod and control valve slide each other only when juxtaposed Gegengepolter magnetic areas on the plunger and control valve slide adjusts.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. Die Figuren der Zeichnung zeigen drei Bewegungsphasen eines Steuerventilsystems für eine Pumpensteuerung im Querschnitt der Pumpe gesehen.An embodiment is shown in the drawing. The figures of the drawing show three phases of movement of a control valve system for a pump control seen in cross-section of the pump.
