Abstract

The closure element to which the invention relates is composed of a cylindrical basic body (1) with a support flange (2) and with a spreading body (4) which is connected to said support flange (2), the position of which spreading body (4) can be varied during use by an external action of force in such a way that said spreading body (4) exerts a radial pressure on the inner wall of the basic body (1) and presses the outer surface of said basic body (1) against a bore wall which is to be closed off.

Description

Verschlusselement für BohrungenClosing element for bores
Die vorliegende Erfindung betrifft ein Verschlusselement zum dichtenden Verschliessen von Bohrungen, mit einem zum Einsetzen in eine zu verschliessende Bohrung vorgesehenen expandierbaren zylindrischen Grundkörper mit nach aussen abstehendem Stützflansch und einem im Innern des Grundkörpers zur Wirkung bringbaren Spreizkörper für den Grundkörper, welcher gleichzeitig einen Abschlussdeckel für die Bohrung des Grundkörpers bildet.The present invention relates to a closure element for sealing closure of holes, with an intended for insertion into a hole to be closed expandable cylindrical body with outwardly projecting support flange and a bring in the interior of the body to effect expansion body for the body, which at the same time a cover for the Bore of the body forms.
Verschlusselemente dieser Art sind als sog. Expander bekannt und dienen als dichte Verschlüsse für Bohrungen bei oft herrschenden hohen Drücken, z.B. bis 1000 bar (siehe z.B. EP 0 364 699 der Anmelderin) . Dabei wird in der Regel ein stopfenförmiger Grundkörper, d.h. eine Hülse mit Abschlussdeckel, mittels eines Expansionskörpers radial aufgespreizt und gegen die Wand der zu verschliessenden Bohrung angelegt (und an dieser formschlüssig verankert) .Closure elements of this type are known as so-called expander and serve as tight seals for bores at often high pressures, e.g. to 1000 bar (see for example EP 0 364 699 of the Applicant). As a rule, a plug-shaped basic body, i. a sleeve with end cover, spread radially by means of an expansion body and against the wall of the hole to be closed created (and anchored to this form-fitting).
Da eine hohen Kräften standhaltende Verankerung gewährleistet sein muss, werden an die Fertigungsqualität der Stopfen und die Vorbereitung der Bohrungen höchste Anforderungen gestellt. Auch eignen sich die bekannten Systeme hauptsächlich für Bohrungen mit relativ kleinem Durchmesser . Aufgabe der vorliegenden Erfindung war die Schaffung eines Verschlusselementes auch für Bohrungen im grosseren Durchmesserbereich, welcher weniger hohe Drücke aushalten muss (z.B. bis 15 bar) und eine geringere Fertigungspräzision verlangt, dafür jedoch äusserst einfach zu bedienen ist, normalen einfachen Verschlussdeckeln jedoch überlegen ist (Anwendung z.B. im Motorenbau als Dichtelement für Bohrungen des Motorblocks). Diese Aufgabe wird bei einem Verschlusselement der eingangs definierten Art erfindungsgemäss durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.Since high-strength anchorage must be guaranteed, the production quality of the plugs and the preparation of the holes are of the highest importance. Also, the known systems are mainly for holes with a relatively small diameter. Object of the present invention was to provide a closure element for drilling in the larger diameter range, which must withstand less high pressures (eg up to 15 bar) and requires less precision manufacturing, but it is extremely easy to use, but normal simple cap is superior (application eg in engine construction as a sealing element for bores of the engine block). This object is achieved according to the invention in a closure element of the type defined by the features of the characterizing part of claim 1.
