Abstract
Description
Die Erfindung betrifft eine Spritzpistole für ein Hochdruckfluid nach dem Oberbegriff des Anspruchs 1.The The invention relates to a spray gun for a high pressure fluid after Preamble of claim 1.
Bei Spritzpistolen, die zum Verspritzen von Hochdruckfluid, beispielsweise Hochdruckwasser, verwendet werden, sind wegen der hohen Drücke von bis zu mehreren tausend bar besondere Sicherheitsmaßnahmen erforderlich, um Unfälle zu vermeiden. Hierzu ist es bekannt, im unbetätigten Zustand das über eine Pumpe geförderte Fluid praktisch drucklos über eine Bypassleitung abfließen zu lassen und zur Betätigung die Bypassleitung über ein Hochdruckventil zu verschließen, das seinerseits durch ein Vorsteuerventil betätigt wird. Problematisch ist hierbei allerdings, daß die Ventilbetätigung über Handkraft zu erfolgen hat, was wegen der hierzu notwendigen großen Kraft nicht nur ermüdend ist, sondern auch dazu führt, daß dem Betätiger nicht angezeigt wird, wann das Hochdruckventil geschlossen ist, da der Auslauf von Fluid über die Bypassleitung aus einer Abführleitung gewöhnlich entfernt vom Betätiger ist, damit dieser nicht naß wird. Wenn das Hochdruckventil aber nicht richtig dichtet, ergibt sich ein entsprechend hoher Verschleiß und damit eine geringe Lebensdauer der Spritzpistole.at Spray guns for spraying high pressure fluid, for example High pressure water, are used because of the high pressures of up to several thousand bar special security measures required to accidents to avoid. For this purpose, it is known in the unactuated state that via a Pump promoted Fluid practically depressurized over drain a bypass line to let and to operate the bypass line over to close a high pressure valve, which in turn by a Pilot valve actuated becomes. The problem here, however, that the valve actuation by manual force has to be done, which is because of the necessary for this large force not only tiring is, but also causes that the actuator does not indicate when the high pressure valve is closed, as the spout of fluid over the bypass line from a discharge line usually removed from the actuator is so that it does not get wet. However, if the high pressure valve does not seal properly, it results correspondingly high wear and tear thus a short life of the spray gun.
Aufgabe der Erfindung ist es, eine Spritzpistole für ein Hochdruckfluid nach dem Oberbegriff des Anspruchs 1 zu schaffen, deren Betätigung wenig ermüdend ist und bei dem die Lebensdauer erhöht ist.task The invention is a spray gun for a high pressure fluid after To provide preamble of claim 1, the operation of little tiring is and where the life is increased.
Diese Aufgabe wird entsprechend den Merkmalen des Anspruchs 1 gelöst.These The object is achieved according to the features of claim 1.
Dadurch, daß bei der Spritzpistole ein vom Ventilstößel des Vorsteuerventils unterbrechbarer Leckageweg vom Hochdruckfluidanschluß um das Hochdruckventil herum in die Bypassleitung vorgesehen ist, die auf den Betätigungshebel ausgeübte Betätigungskraft über eine Kraftübertragungsfeder auf den Ventilstößel des Vorsteuerventils übertragen wird und ein Anschlag für den Betätigungshebel in dessen Betätigungsstellung vorgesehen ist, kann die Handkraft den Betätigungshebel leicht bis zum Anschlag drücken, da die Kraftübertragungsfeder die hierzu notwendige Kraft zum Drücken des Betätigungshebels entsprechend erniedrigt, wobei der Anschlag einen definierten Hub ergibt, so daß der Verschleiß entsprechend niedrig gehalten und die Lebensdauer erhöht werden können.Thereby, that at the spray gun a puncture by the valve stem of the pilot valve interruptible from the high-pressure fluid connection the high-pressure valve is provided around in the bypass line, the on the operating lever practiced Operating force over a Power transmission spring on the valve stem of the Pilot valve is transmitted and a stop for the operating lever in its operating position is provided, the manual force, the operating lever easily to Press stop, because the power transmission spring the necessary force for pressing the operating lever lowered accordingly, the attack a defined stroke results, so that the Wear accordingly kept low and the life can be increased.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further Embodiments of the invention are the following description and the dependent claims refer to.
