DruckregelventilPressure control valve
Die Erfindung "betrifft'ein Druckregelventil zur Lieferung eines Mediumdrucks, der ein im wesentlichen fester Wert über einem Regeldruck ist.The invention "relates to a pressure control valve for supplying a medium pressure, which is an essentially fixed value above a control pressure.
Ein Druckregelventil gemäß der Erfindung ist gekennzeichnet durch ein in einem Zylinder verschiebbares Ventilglied, wobei ein Ende des Zylinders mit einer Druckmittelquelle in Verbindung steht, eine periphere Nut in dem Zylinder vorgesehen ist, die mit einem Abfluß in Verbindung steht und durch das Ventilglied mit dessen Bewegung in Richtung auf das andere Ende des Zylinders durch das Druckmittel in dem einen Ende des Zylinders freilegbar ist, in dem anderen Ende des Zylinders angeordnete Federmittel und Mittel zur Erzeugung eines Regeldrucks, der dem anderen Ende des Zylinders zuleitbar ist, wobei eine solche Anordnung vorgesehen ist, daß das Ventilglied zur Regelung des Drucks in dem einen Ende des Zyliiders auf einen Wert wandert, der proportional zum Regeldruck plus einem im wesentlichen festliegenden Wert ist, welcher durch die Pedermittel bestimmt ist.A pressure regulating valve according to the invention is characterized by a Valve member displaceable in a cylinder, one end of the cylinder being connected to a pressure medium source, a peripheral one Groove is provided in the cylinder, which is in communication with a drain and through the valve member with its movement in the direction of the other end of the cylinder can be exposed by the pressure medium in one end of the cylinder, arranged in the other end of the cylinder Spring means and means for generating a regulating pressure which the other Can be fed to the end of the cylinder, such an arrangement being provided that the valve member for regulating the pressure in one end of the cylinder migrates to a value that is proportional to the control pressure plus a substantially fixed value which is determined by the Peder means is.
Die Erfindung ist nachstehend an Hand eines Ausführungsbeispiels unter BezuHgnahme auf die Zeichnung näher erläutert.The invention is shown below on the basis of an exemplary embodiment Referring to the drawing explained in more detail.

Ein Ende des Zylinders 10 steht mit einer Leitiung 12 in Verbindung, die eine Drosselstelle I3 an ihrem Eingang in den Zylinder aufweist. Die Leitung 12 steht mit dem Auslaß einer Pumpe I4 inIn the drawing, a cylinder 10 is shown in which a displaceable Valve member 11 is seated .. One end of the cylinder 10 is connected to a line 12 in connection with a throttle point I3 at its entrance to the cylinder having. The line 12 is connected to the outlet of a pump I4

Verbindung. In die Wand des Zylinders 10 ist eine öffnung 16 eingeformt, die um ein größeres oder kleineres Maß durch das Yentilglied 11 freigelegt werden kann. Der Mediumdruck im Zylinder beaufschlagt die angrenzende Seite des Yentilglieds 11, um eine Kraft zu erzeugen, der mechanische Mittel entgegenwirken. Das Yentilglied 11 wird durch die vorherrschende Kraft bewegt, bis eine Gleichgewichtsstellung erreicht wird, in der die Kraft, mit der das Ventilglied 11 auf Grund des Kediumdrucks im Zylinder 10 beaufschlagt wird, die von den mechanischen Mitteln erzeugte Kraft kompensiert. Falls der !Förderdruck der Pumpe 14 steigt, nimmt das Ventilglied 11 eine neue gleichgewichtsstellung ein.Link. An opening 16 is formed in the wall of the cylinder 10, which are exposed by the valve member 11 to a greater or lesser extent can be. The medium pressure in the cylinder acts on the adjacent one Side of the y valve member 11 to generate a force counteracting the mechanical means. The Yentil member 11 is dominated by the Force moves until an equilibrium position is reached in which the force with which the valve member 11 due to the Kediumdruck in the cylinder 10 is applied, the force generated by the mechanical means compensated. If the delivery pressure of the pump 14 increases, the valve member decreases 11 a new equilibrium position.
Im beschriebenen Ausführungsbeispiel wird die mechanische Kraft durch zwei Fliehkraftgewichte 17 erzeugt, die im Kreis wandern und die damit auf das Ventilglied 11 eine Kraft ausüben, die sich entsprechend dem Quadrat der Drehzahl ändert, mit der die Gewichte umlaufen. Der Mediumdruck im Zylin- · der 10 ist damit proportional zum Quadrat der Drehzahl, mit der die Gewichte umlaufen.In the embodiment described, the mechanical force is divided by two Centrifugal weights 17 generated, which wander in a circle and thus on the Valve member 11 exert a force which changes according to the square of the speed at which the weights rotate. The medium pressure in the cylinder 10 is therefore proportional to the square of the speed at which the weights rotate.
Die Druckseite der Pumpe 14 steht ferner mit einem Ende eines Zylinders in Verbindung, in dem sich ein verschiebbares Ventilglied 19 befindet. Das Ventilglied wird durch Federmittel in der Form einer Feder 20 entgegengesetzt zur Kraft beaufschlagt, die von dem Mediumdruck erzeugt wird, welcher von der Pumpe erzeugt wird, der auf das Ventilglied einwirkt. Die von der Feder 20 ausgeübte Kraft wird durch die Kraft ergänzt, die von unter Druck stehendem Medium erzeugt wird, das vom Zylinder 10 abgeleitet wird.The pressure side of the pump 14 is also at one end of a cylinder in connection, in which a displaceable valve member 19 is located. That Valve member is acted upon by spring means in the form of a spring 20 opposite to the force that is generated by the medium pressure, which is generated by the pump acting on the valve member. The force exerted by the spring 20 is supplemented by the force exerted by under pressure standing medium is generated, which is derived from the cylinder 10.
In die Wand des Zylinders 18 ist eine periphere Hut 21 eingeformt, die mit einem Abfluß in Verbindung steht, wobei die Eut einen Überlaufweg bildet, der vom Ventilglied 19gesteuert wird. Im Gebrauch werden der Mediumdruck in dem einen Ende des Zylinders 18 und damit der Förderdruck der Pumpe so geregelt, daß im vorliegenden Ausführungsbeispiel dieser gleich dem Druck im Zylinder 1o plus einem festliegenden Wert ist, der durch die von der Feder ausgeübte Kraft bestimmt wird.In the wall of the cylinder 18, a peripheral hat 21 is formed, which with communicates with a drain, the ud forming an overflow path, which is controlled by the valve member 19. In use, the medium pressure in one end of the cylinder 18 and thus the delivery pressure of the pump controlled so that in the present embodiment this is equal to the The pressure in the cylinder is 1o plus a fixed value determined by the force exerted by the spring.
Der Gebrauch einer ringförmigen Hut als den Überlaufweg vom Zylinder 18 bedeutet, daß eine große Änderung in der Größe des Überlaufwegs für eineThe use of an annular hat as the overflow path from cylinder 18 means that a large change in the size of the overflow path for a

kleine Bewegung des Yentilglieds 19 vorhanden ist. Die Federkraft ist damit über einen großen Berich an Förderwerten der Pumpe 14 im wesentlichen konstant.small movement of the valve member 19 is present. The spring force is thus essentially over a large range of delivery values of the pump 14 constant.
Ein Ventil der beschriebenen Art ist von besonderem Nutzen in einer Kraftstoffpumpvorrichtung zur Zuleitung von Kraftstoff in einen Brennkraftemotor. In einer solchen Vorrichtung ist es häufig wünschenswert, daß verschiedene Regelfunktionen durch auf Druck ansprechende Glieder ausgeführt werden, die einem Druck ausgesetzt werden, der sich zum Quadrat der Drehzahl ändert, mit der die Vorrichtung läuft. Dieser Druck kann vom Zylinder 10 erhalten werden. Gleichzeitig ist es wünschenswert, andere Regelfunktionen zu erhalten, die durch Glieder ausgeführt werden, die einem Druck ausgesetzt werden, der um einen im wesentlichen festen Wert über dem Druck liegt, der sich zum Quadrat der Drehzahl ändert. Dieser Druck wird vom Zylinder 18 erhalten.A valve of the type described is of particular use in one Fuel pump device for supplying fuel to an internal combustion engine. In such a device it is often desirable that various control functions by pressure-responsive members which are subjected to a squared pressure the speed at which the device is running changes. This pressure can be obtained from the cylinder 10. At the same time it is desirable to have other control functions carried out by members subjected to a pressure which is above a substantially fixed value is the pressure, which changes to the square of the speed. This pressure is obtained from the cylinder 18.
