Abstract
Description
Die Erfindung betrifft einen Zylinder mit einem separaten Verschluss gemäß dem Oberbegriff von Patentanspruch 1. The invention relates to a cylinder with a separate closure according to the preamble of
Aus der
Kostentreibend an dieser Konstruktion ist die Armierungshülse, die beim Spritzvorgang zur Herstellung des Anschlussorgans in die Spritzform eingelegt sein muss, um eine optimale Verbindung zwischen der Armierungshülse und dem Kunststoffkörper des Anschlussorgans zu erreichen. The driving force behind this design is the armor sleeve, which must be inserted into the injection mold during the injection process for producing the connection member in order to achieve an optimum connection between the armor sleeve and the plastic body of the connection member.
Die Aufgabe der vorliegenden Verbindung besteht darin, eine kostengünstige Verbindung zwischen einem Verschlussorgan und einem Zylinder zu realisieren. The object of the present invention is to realize a cost-effective connection between a closure member and a cylinder.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Verschluss zumindest partiell radial elastisch ausgeführt ist und ein verschlussseitiges Formschlusselement in ein zylinderseitiges Formschlusselement einrastet. According to the invention the object is achieved in that the closure is at least partially radially elastic and a closure-side positive-locking element engages in a cylinder-side positive-locking element.
Der große Vorteil besteht darin, dass sich die Montage des Verschlusses vereinfacht, da kein plastischer Verformungsaufwand für die Formschlussverbindung notwendig ist. The big advantage is that the assembly of the closure is simplified because no plastic deformation effort for the positive connection is necessary.
Gemäß einem vorteilhaften Unteranspruch ist das verschlussseitige Formschlusselement als mindestens ein radial elastischer Vorsprung ausgeführt. Der Vorsprung kann als massive Nocke oder auch als Zunge ausgeführt sein. According to an advantageous embodiment, the closure-side form-fitting element is designed as at least one radially elastic projection. The projection can be designed as a solid cam or as a tongue.
Um den Fertigungsaufwand am Zylinder zu minimieren weist der Zylinder mindestens ein Aufnahmefenster für die Formschlussverbindung auf. Umformrisse, wie sie bei einer Versickung auftreten können, sind durch diese vorteilhafte Ausgestaltung der Formschlussverbindung ausgeschlossen. To minimize the manufacturing effort on the cylinder, the cylinder has at least one receiving window for the positive connection. Forming cracks, as they can occur in a potting, are excluded by this advantageous embodiment of the positive connection.
Zur Aufnahme von axialen Druckkräften weist der Verschluss einen Absatz auf, der an einer Stirnseite des Zylinders anliegt. For receiving axial compressive forces, the closure has a shoulder which bears against an end face of the cylinder.
Zur leichteren Verriegelung der Formschlussverbindung weist der elastische Vorsprung in Einschubrichtung des Verschlusses in den Zylinder eine Montageschräge auf. For easier locking of the positive connection, the elastic projection in the insertion direction of the closure in the cylinder on a mounting slope.
Um Belastungen in Auszugrichtung des Verschlusses besser aufnehmen zu können, weist der Vorsprung eine axiale Blockierfläche entgegen der Bewegung in Auszugrichtung des Verschlusses auf. In order to absorb loads in the extension direction of the closure better, the projection has an axial blocking surface against the movement in the extension direction of the closure.
Dabei ist vorgesehen, dass die Blockierfläche als Planfläche ausgeführt ist. Die auftretenden Auszugkräfte werden dann vollflächig aufgenommen. It is provided that the blocking surface is designed as a plane surface. The pull-out forces are then absorbed over the entire surface.
Zur Vermeidung von Leckagen zwischen dem Verschluss und dem Zylinder weist der rohrförmige Abschnitt des Verschlusses eine Dichtung zur Innenmantelfläche des Zylinders auf. To avoid leakage between the closure and the cylinder, the tubular portion of the closure has a seal to the inner surface of the cylinder.
Optional kann der rohrförmige Abschnitt zumindest im Bereich der Formschlussverbindung innenseitig eine Stützhülse aufweisen, um die Formschlussverbindung zu verriegeln. Optionally, the tubular section can have a support sleeve on the inside, at least in the area of the form-locking connection, in order to lock the form-locking connection.
Anhand der folgenden Figurenbeschreibung soll die Erfindung näher erläutert werden. The invention will be explained in more detail with reference to the following description of the figures.
