Abstract
Die Erfindung betrifft die Ausbildung eines Kaltstartventils mit einem Steuerkolben, mittels dem ein Ein- und Ausgangsanschluss des Kaltstartventils fs Steuerkolbens mit dem Ausgangsanschluss des Kaltstartventils verbunden ist und die andere Steuerseite des Steuerkolbens mit einem Steuerdruckanschluss des Kaltstartventils verbunden und zusätzlich mit einer Vorspannfeder kraftbeaufschlagt ist. Erfindungsgemäß ist ein zusätzlicher Zwangsschaltmechanismus zur (die betriebsmittelbezogene Steuerungsfunktion) überlagernden oder unterstützenden Verschiebung des Steuerkolbens für ein Verbinden des Ein- und Ausgangsanschlusses vorgesehen.The invention relates to the design of a cold start valve with a control piston, by means of which an input and output connection of the cold start valve fs control piston is connected to the output connection of the cold start valve and the other control side of the control piston is connected to a control pressure connection of the cold start valve and is additionally acted upon by a biasing spring. According to the invention, an additional forced switching mechanism for shifting the control piston (which is related to the resource-related control function) or to support it is provided for connecting the input and output connection.
Description
Die vorliegende Erfindung betrifft ein Kaltstartventil gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a cold start valve according to the preamble of
Fahrzeuge mit Brennkraftmaschinen als Hauptantriebseinrichtung sowie mit einer Anzahl hydraulischer Verbraucher besitzen in der Regel eine Speise- oder Ladepumpe, die über ein mechanisches Getriebe mit der Brennkraftmaschine verbunden ist und daher bereits beim Startvorgang der Brennkraftmaschine mit angetrieben wird. Um die hierbei entstehende Drehmomentbelastung auf den Anlasser des Brennkraftmaschine möglichst klein zu halten, ist der Speise- oder Ladepumpe für gewöhnlich ein Kaltstartventil zugeordnet, welches temporär den Eingangs- und Ausgangsanschluss der Speise- oder Ladepumpe kurzschließt und somit einen Neutraldurchlauf bewirkt.Vehicles with internal combustion engines as the main drive device and with a number of hydraulic consumers usually have a feed or charge pump, which is connected via a mechanical transmission with the internal combustion engine and is therefore already driven during the starting process of the internal combustion engine. In order to keep the resulting torque load on the starter of the internal combustion engine as small as possible, the feed or charge pump is usually associated with a cold start valve, which temporarily shorts the input and output terminal of the feed or charge pump and thus causes a neutral pass.
Aus dem Stand der Technik beispielsweise gemäß der
Des Weiteren existieren im Stand der Technik sogenannte Schutzventile, welche eine Betriebsmittelanlage beispielsweise bei kaltem und damit zähflüssigem Betriebsmittel vor Beschädigung schützen sollen. Ein solches Schutzventil ist beispielsweise in der Veröffentlichung
In diesem Fall besteht das Schutzventil aus einem fluidgesteuerten Druckbegrenzungsventil, das in eine Bypassleitung für einen Betriebsmittelfilter zwischengeschaltet ist. Eine Steuerseite des Druckbegrenzungsventils ist an eine stromaufwärtige Seite des Filters und eine andere, zusätzlich federvorgespannte Steuerseite des Druckbegrenzungsventils ist an eine stromabwärtige Steuerseite des Filters angeschlossen. Über die Vorspannfeder ist das Druckbegrenzungsventil so eingestellt, dass es bei Erreichen eines bestimmten Druckgefälles (Druckdifferenz auf 6 bar eingestellt) zwischen der stromaufwärtigen und stromabwärtigen Seite des Filters öffnet und Betriebsmittel in den Betriebsmitteltank entspannt.In this case, the protection valve consists of a fluid-controlled pressure relief valve, which is interposed in a bypass line for a resource filter. One control side of the pressure relief valve is connected to an upstream side of the filter and another, additionally spring biased control side of the pressure relief valve is connected to a downstream control side of the filter. About the biasing spring, the pressure relief valve is set so that it opens when reaching a certain pressure gradient (pressure difference set to 6 bar) between the upstream and downstream side of the filter and relaxes resources in the resource tank.
Wie aus dem beschriebenen Stand der Technik zu ersehen ist, lässt ich mit einem Kaltstartventil, wie es aus der
Angesichts dieser Sachlage besteht die Aufgabe der vorliegenden Erfindung darin, mit geringem konstruktiven Aufwand ein aus dem Stand der Technik bekanntes Schutzventil so weiterzubilden, dass ein ausreichender Schutz des Filters und der gesamten Betriebsmittelanlage vor hohen Drücken und gleichzeitig ein Kaltstart mit geringer Drehmomentbelastung für den Anlasser einer Brennkraftmaschine gewährleistet ist.In view of this situation, the object of the present invention is to develop with little design effort known from the prior art protection valve so that adequate protection of the filter and the entire equipment system against high pressures and at the same time a cold start with low torque load for the starter Internal combustion engine is guaranteed.
Diese Aufgabe wird durch ein Kaltstartventil mit den Merkmalen des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a cold start valve having the features of
Der Kern der Erfindung besteht demzufolge in der Ausbildung eines Kaltstartventils mit einem Steuerkolben, mittels dem ein Ein- und Ausgangsanschluss des Kaltstartventils fluidverbindbar sind, wobei die eine Steuerseite des Steuerkolbens mit dem Ausgangsanschluss des Kaltstartventils verbunden ist und die andere Steuerseite des Steuerkolbens mit einem Steuerdruckanschluss des Kaltstartventils verbunden und zusätzlich mit einer Vorspannfeder kraftbeaufschlagt ist.The core of the invention is therefore in the formation of a cold start valve with a control piston, by means of which an input and output port of the cold start valve are fluid-connectable, wherein the one control side of the control piston is connected to the output port of the cold start valve and the other control side of the control piston with a control pressure port of the Cold start valve connected and additionally subjected to a biasing force.
Erfindungsgemäß ist ein zusätzlicher Zwangsschaltmechanismus zur (die betriebmittelbezogene Steuerungsfunktion) überlagernden oder unterstützenden Verschiebung des Steuerkolbens für ein Verbinden des Ein- und Ausgangsanschlusses vorgesehen.According to the invention, an additional forced switching mechanism is provided for overriding or supporting displacement of the control piston for connecting the input and output ports.
Hierdurch ist es möglich, ein bereits aus dem Stand der Technik bekanntes Schutzventil etwa in der Form eines Druckbegrenzungsventils durch additives Modifizieren mit dem Zwangsschaltmechanismus mit der zusätzlichen Funktion eines Kaltstartventils auszustatten, welches eine Schaltung des Ventils in einen im Wesentlichen drucklosen Neutraldurchlauf erlaubt.This makes it possible to equip an already known from the prior art protection valve in the form of a pressure relief valve by additive Modifikations with the forced switching mechanism with the additional function of a cold start valve, which allows a circuit of the valve in a substantially unpressurized neutral pass.
Die Erfindung wird nachstehend anhand eines bevorzugten Ausführungsbeispiels unter Bezugnahme auf die begleitenden Zeichnungen näher erläutert.The invention will be explained below with reference to a preferred embodiment with reference to the accompanying drawings.
