Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Einspritzventil für ein Fluid, insbesondere für Kraftstoff, nach dem Oberbegriff des Anspruchs 1.The invention is based on an injection valve for a fluid, in particular for fuel, according to the preamble of claim 1.
Bei einem bekannten Kraftstoffeinspritzventil (
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Einspritzventil mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass durch die Aufteilung des Anschlussstücks in Ober- und Unterteil das Einstellmittel montagefreundlich mittels Stoffschluss, z. B. Schweißen, im Anschlussstück festgelegt werden kann. Die stoffschlüssige Verbindung, die vorzugsweise mittels einer Schweißnaht zwischen Einstellmittel und Unterteil des Anschlussstücks einerseits und Ober- und Unterteil des Anschlussstücks andererseits hergestellt ist, gewährleistet einerseits eine zuverlässige Fixierung des Einstellmittels, die sich nicht durch thermische und/oder axiale Belastungen löst oder verändert, und andererseits eine zuverlässige Abdichtung des Einstellmittels gegenüber dem Anschlussstück, so dass insbesondere dann, wenn – wie üblich – das Einstellmittel mit dem Fluidzulauf in Verbindung steht, Fluid nicht zu dem nichtfluidresistenten Aktor gelangen und diesen beschädigen kann.The injector according to the invention with the features of claim 1 has the advantage that by adjusting the connection piece in the upper and lower part of the adjustment means easy to install by means of material connection, for. B. welding, can be set in the connector. The cohesive connection, which is preferably made by means of a weld between adjusting and lower part of the connector on the one hand and the upper and lower part of the connector on the other hand, on the one hand ensures a reliable fixation of the adjusting, which does not dissolve or change by thermal and / or axial loads, and on the other hand a reliable sealing of the adjusting means relative to the connecting piece, so that in particular when - as usual - the adjusting means is in communication with the fluid inlet, fluid can not reach the non-fluid-resistant actuator and damage it.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Einspritzventils möglich.The measures listed in the further claims advantageous refinements and improvements of the claim 1 injection valve are possible.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist an der Trennstelle von Ober- und Unterteil eine von Ober- und Unterteil eingeschlossene Fluidkaverne angeordnet, in der einerseits ein im Oberteil verlaufender erster Kanalabschnitt des Zulaufkanals und andererseits ein im Unterteil verlaufender zweiter Kanalabschnitt des Zulaufkanals mündet. Das Einstellmittel ragt in die Fluidkaverne hinein und ist an seiner Eintrittsstelle in die Fluidkaverne mit dem Unterteil stoffschlüssig verbunden, vorzugsweise verschweißt. Durch die Ausbildung der Fluidkaverne ist in konstruktiv einfacher Weise eine Aufteilung des Zulaufkanals für das Fluid auf Ober- und Unterteil des Anschlussstücks und zugleich die stoffschlüssige Verbindung des Einstellmittels mit dem Unterteil in einfacher Weise realisierbar.According to an advantageous embodiment of the invention, a fluid cavern enclosed by upper and lower part is arranged at the separation point of the upper and lower part, in which on the one hand in the upper part extending first channel portion of the inlet channel and on the other hand, a running in the lower second channel portion of the inlet channel opens. The adjusting means protrudes into the fluid cavern and is integrally connected, preferably welded, at its entry point into the fluid cavern with the lower part. Due to the design of the fluid cavern in a structurally simple manner a division of the inlet channel for the fluid on the upper and lower part of the connector and at the same time the cohesive connection of the adjusting means with the lower part in a simple manner.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist die Fluidkaverne von je einer im Ober- und Unterteil des Anschlussstücks vorhandenen Ausnehmung gebildet. Das Oberteil taucht formschlüssig in die Ausnehmung im Unterteil ein und ist längs des Umlaufrandes der Ausnehmung im Unterteil mit dem Unterteil formschlüssig verbunden, vorzugsweise verschweißt. Mit dem formschlüssigen Eintauchen des Oberteils in die Ausnehmung im Unterteil und durch das vorzugsweise Herstellen einer Schweißnaht längs des Umlaufrands der Ausnehmung im Unterteil lässt sich die Fluidkaverne nach außen hin zuverlässig abdichten.According to an advantageous embodiment of the invention, the fluid cavern is formed by a respective existing in the upper and lower part of the connector recess. The upper part dips positively into the recess in the lower part and is connected along the peripheral edge of the recess in the lower part with the lower part in a form-fitting manner, preferably welded. With the positive immersion of the upper part in the recess in the lower part and by preferably producing a weld along the peripheral edge of the recess in the lower part, the fluid cavern can be reliably sealed to the outside.
