Abstract
Description
Die Erfindung betrifft einen Verbindungsstutzen für die Kurbelgehäuseentlüftung einer Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a connecting piece for the Crankcase ventilation one Internal combustion engine according to the preamble of patent claim 1.
In der
Aufgabe der Erfindung ist es daher, ein zuverlässiges und dauerhaltbares Abdichtungssystem für die elektrischen Heizwiderstände des Verbindungsstutzens zu entwickeln.The object of the invention is therefore a reliable and durable sealing system for the electrical heating resistors of the To develop connecting pieces.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the Features of claim 1 solved.
Der erfindungsgemäße Verbindungsstutzen zeichnet sich dadurch aus, dass die Metallhülse im Bereich des Heizwiderstandes gegenüber einem Flanschabschnitt des Verbindungsstutzens elastisch abgedichtet ist. Damit wird trotz des unterschiedlichen Wärmeausdehnungsverhaltens von Verbindungsstutzen und Metallhülse die Entstehung von Dichtspalten zuverlässig verhindert. Das Abdichtungskonzept zeichnet sich neben seiner Zuverlässigkeit und Dauerhaltbarkeit durch einen einfachen und fertigungsprozesssicheren Aufbau aus.The connecting piece according to the invention draws is characterized in that the metal sleeve in the area of the heating resistor across from a flange portion of the connecting piece sealed elastically is. In spite of the different thermal expansion behavior of Connection piece and metal sleeve reliably prevents the formation of sealing gaps. The sealing concept stands out in addition to its reliability and durability through a simple and reliable manufacturing process.
Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen aufgeführt.Further, embodying the invention Features are in the subclaims listed.
Auf vorteilhafte Art und Weise sind auf der Außenmantelseite der Metallhülse im Bereich des Heizwiderstandes Ringnuten vorgesehen, in denen elastische Dichtringe aufgenommen sind. Die Dichtringe bestehen aus einem Silikonmaterial, das auch bei extremen Minustemperaturen (bis –35° C) seine Grundelastizität beibehält.Are in an advantageous way on the outer shell side the metal sleeve Ring grooves are provided in the area of the heating resistor, in which elastic Sealing rings are included. The sealing rings are made of a silicone material, that maintains its basic elasticity even at extreme sub-zero temperatures (down to –35 ° C).
Die Heizwiderstände sind vorzugsweise als PTC-Elemente ausgebildet, die auf der Außenmantelseite der Metallhülse beispielsweise aufgelötet oder aufgeklebt sind.The heating resistors are preferably PTC elements trained on the outer shell side the metal sleeve for example soldered or are glued on.
Die Metallhülse weist einen konisch verlaufenden Endabschnitt auf, der beim Einsetzen in den Kunststoff-Verbindungsstutzen leicht eingepresst wird. Damit ist die Metallhülse verliersicher im Flanschabschnitt des Verbindungsstutzens gehalten.The metal sleeve has a tapered End section on which when inserted into the plastic connector is pressed in easily. The metal sleeve is thus captive in the flange section of the connector.
Der auf der anderen Stirnseite der Metallhülse ausgebildete Kragen weist eine Montage- und/oder Positionierhilfe in Form von zwei auf der Kragenaußenseite vorgesehenen Aussparungen auf. Damit ist u. a. sicher gestellt, dass die an den PTC-Widerständen befestigten Kontaktelemente mit den im Flanschabschnitt des Verbindungsstutzens eingebrachten Kontaktelementen korrespondieren.The one on the other end of the metal sleeve trained collar has an assembly and / or positioning aid in the form of two on the outside of the collar provided recesses. So u. a. made sure that the on the PTC resistors attached contact elements with the inserted in the flange section of the connecting piece Contact elements correspond.
