Abstract
Verbindungsstutzen (10) für die Kurbelgehäuseentlüftung einer Brennkraftmaschine, mit einem Flanschabschnitt (12), in dem eine elektrische beheizbare Metallhülse (24) aufgenommen ist, an deren Außenmantelseite mindestens ein elektrischer Heizwiderstand (30) befestigt ist, der über einen elektrischen Anschluss (22) mit Strom versorgbar ist, wobei die Metallhülse (24) auf ihrer Außenmantelseite im Bereich des Heizwiderstandes (30) Ringnuten aufweist, in denen zur Abdichtung gegenüber dem Flanschabschnitt (12) elastische Dichtringe (26, 28) eingesetzt sind, dadurch gekennzeichnet, dass die Metallhülse (24) an einer ersten Stirnseite einen konisch verlaufenden Endabschnitt (35) und an einer zweiten Stirnseite einen Kragen (36) aufweist, an dem eine Montage- und/oder Positionierhilfe in Form von zwei auf der Kragenaußenseite ausgebildeten Aussparungen (38, 40) vorgesehen ist.connecting pieces (10) for the crankcase ventilation a Internal combustion engine, with a flange portion (12) in which a electric heatable metal sleeve (24) is received, on the outer shell side at least one electrical heating resistor (30) is attached, which has a electrical connection (22) can be supplied with power, wherein the metal sleeve (24) on its outer shell side has in the region of the heating resistor (30) annular grooves in which for sealing against the Flange portion (12) elastic sealing rings (26, 28) used are, characterized in that the metal sleeve (24) at a first end face a tapered end portion (35) and at a second End face has a collar (36) on which a mounting and / or Positioning aid in the form of two on the collar outside formed recesses (38, 40) is provided.
Description
Die Erfindung betrifft einen Verbindungsstutzen für die Kurbelgehäuseentlüftung einer Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a connecting piece for the crankcase ventilation a Internal combustion engine according to the preamble of patent claim 1.

Aufgabe der Erfindung ist es daher, ein zuverlässiges und dauerhaltbares Abdichtungssystem für die elektrischen Heizwiderstände des Verbindungsstutzens zu entwickeln.task The invention therefore provides a reliable and durable sealing system for the electrical heating resistors to develop the connecting piece.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Der erfindungsgemäße Verbindungsstutzen zeichnet sich dadurch aus, dass die Metallhülse an einer ersten Stirnseite einen konisch verlaufenden Endabschnitt und an einer zweiten Stirnseite einen Kragen aufweist, an dem eine Montage- und/oder Positionierhilfe in Form von zwei auf der Kragenaußenseite ausgebildeten Aussparungen vorgesehen ist.Of the inventive connecting piece draws characterized in that the metal sleeve at a first end face a tapered end portion and at a second end face a collar on which an assembly and / or positioning aid in the form of two formed on the collar outside recesses is provided.
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.In order to is despite the different thermal expansion behavior of Connecting piece and metal sleeve Reliably prevents the formation of sealing gaps. The sealing concept stands apart from its reliability and durability through a simple and production process safe construction.
Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen aufgeführt.Further, the invention ausgestaltende features are listed in the dependent claims.
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.On advantageous manner are on the outer shell side of the metal sleeve in the area the heating resistor provided annular grooves in which elastic sealing rings are included. The sealing rings are made of a silicone material, which retains its basic elasticity even at extreme minus 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 formed as PTC elements 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 portion which upon insertion in the plastic connecting piece is pressed slightly. Thus, the metal sleeve is captive in the flange held the connecting piece.
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.Of the has on the other end face of the metal sleeve formed collar an assembly and / or Positioning aid in the form of two on the collar outside provided recesses. This is u. a. made sure that at the PTC resistors fastened contact elements with the introduced in the flange portion of the connecting piece Contact elements correspond.
