ölfiltereinsatzoil filter insert

Die Erfindung bezieht sich auf ölfiltereinsätze für ölfilter in Heizungsanlagen. The invention relates to oil filter inserts for oil filters in heating systems.

Diese Filtereinsätze werden üblicherweise mittels Dreh-Bajonettverschluß mit dem Filterkopf verbunden. Damit ist eine leichte und schnelle Auswechselbarkeit sichergestellt.These filter inserts are usually connected to the filter head using a rotating bayonet lock. This ensures that they can be replaced quickly and easily.

Der Filtereinsatz besteht aus dem Haltering mit dem Bajonettverschluß und dem Filterkörper aus porösem Sinterkunststoff, der die im Heizöl vorhandenen Verunreinigungen zurückhält.The filter insert consists of the retaining ring with the bayonet lock and the filter body made of porous sintered plastic, which retains the impurities present in the heating oil.

Der Filterkörper besitzt zur Erhöhung der Filterfläche zusätzlich ein Innenrohr mit entsprechende Böden.To increase the filter surface, the filter body also has an inner tube with corresponding bases.

Der Haltering und der Filterkörper werden üblicherweise durch Schweißen oder Verkleben miteinander verbunden.The retaining ring and the filter body are usually connected by welding or gluing.

Die Erfindung besteht nun darin, den aufwendigen Schweiß- oder Verklebevorgang durch eine einfache Klemm- bzw. Rastverbindung zu ersetzen.The invention now consists in replacing the complex welding or gluing process with a simple clamping or locking connection.

Erfindungsgemäß wird das dadurch erreicht, daß der Haltering einseitig einen Flansch besitzt mit angeformtem Bajonettverschluß und anderseitig mit Klemm- bzw. Rastfüßen versehen ist. Diese Klemm- bzw. Rastfüße sind mit vorstehenden Nasen bzw. Rippen versehen, die nach der Montage sowohl ein Verdrehen als auch ein Abziehen des Filterkörpers von dem Haltering verhindern. Der Haltering besteht dabei aus einem härteren Kunststoff als der Filterkörper.According to the invention, this is achieved in that the retaining ring has a flange on one side with a molded-on bayonet lock and is provided with clamping or locking feet on the other side. These clamping or locking feet are provided with protruding noses or ribs which, after assembly, prevent the filter body from twisting or being pulled off the retaining ring. The retaining ring is made of a harder plastic than the filter body.

Die Erfindung sei anhand der Figuren 1 und 2 erläutert.The invention is explained with reference to Figures 1 and 2.

Die Figur 1 zeigt den Filtereinsatz mit dem Haltering 1, dem Bajonettverschluß 2 und dem Filterkörper 3. An dem Haltering 1 sind Klemmbzw. Rastfüße 4 angeformt, deren Nasen 5 (härteres Material) in den Filterkörper 3 (weicheres Material) eindringen.Figure 1 shows the filter insert with the retaining ring 1, the bayonet lock 2 and the filter body 3. Clamping or locking feet 4 are formed on the retaining ring 1, the lugs 5 (harder material) of which penetrate into the filter body 3 (softer material).

Die Klemm- bzw. Rastfüße U sind innen mit Längsrippen 6 versehen, die sich fest gegen den zylindrischen Teil bzw. mit entsprechenden Ausnehmungen versehenen Innenrohr 7 des Filterkörpers 3 legen und mit diesem eine drehfeste Verbindung bilden.The clamping or locking feet U are provided with longitudinal ribs 6 on the inside, which lie firmly against the cylindrical part or the inner tube 7 of the filter body 3 provided with corresponding recesses and form a rotationally fixed connection with it.

Der vom Filterkörper 3 übergriffene Bereich 8 des Halteringes 1 ist mit einer umlaufenden Erhebung 9 versehen, die sich in den Filterkörper eindrückt und keine größeren Undichtigkeiten erlaubt, als der Porösität des Filterkörpers entspricht.The area 8 of the retaining ring 1 that is overlapped by the filter body 3 is provided with a circumferential elevation 9 that is pressed into the filter body and does not allow any leaks that are greater than the porosity of the filter body.

Figur 2 zeigt die Draufsicht der Figur 1.Figure 2 shows the top view of Figure 1.
