Abstract

A ring-shaped plastic end disc (1), e.g. made of polyamide, for a fuel or lubricating oil filter in a combustion engine, comprises a sealing ring (3) made of an elastomer, e.g. silicone rubber. The ring has adhesion additives and is formed onto the end of the disc.

Description

Die Erfindung betrifft eine ringförmige Kunststoff- Endscheibe aus insbesondere Polyamid für ein radial durchströmbares Ringfilter nach dem Oberbegriff des Patentanspruchs 1. The invention relates to an annular plastic End plate made in particular of polyamide for a radial flow-through ring filter according to the preamble of Claim 1.

Eine solche Endscheibe ist aus EP 0 945 160 A1 bekannt. Such an end plate is known from EP 0 945 160 A1.

Die Erfindung beschäftigt sich mit dem Problem, eine kostengünstiger herstellbare, qualitativ zumindest gleichwertige gattungsgemäße Kunststoff-Endscheibe bereit zu stellen. The invention deals with the problem of a Cost-effective to produce, at least equivalent in quality to provide generic plastic end plate.

Gelöst wird diese Aufgabe durch die Ausbildung einer gattungsgemäßen Kunststoff-Endscheibe nach dem kennzeichnenden Merkmal des Patentanspruchs 1. This task is solved by training a Generic plastic end plate according to the characteristic Feature of claim 1.

Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche. Advantageous refinements are the subject of Dependent claims.

Die Erfindung beruht auf dem allgemeinen Gedanken, herausgefunden zu haben, dass für den gattungsgemäßen Dichtring Silikonkautschuk bei einer entsprechenden Materialeinstellung, die einerseits eine feste Anformung an die Kunststoff- Endscheibe erlaubt und andererseits eine ausreichende Öl- und/oder Kraftstoffbeständigkeit gewährleistet, eine erhebliche Kosteneinsparung gegenüber vergleichbaren vorbekannten Ausführungen ermöglicht. The invention is based on the general idea to have found that for the generic sealing ring Silicone rubber with an appropriate material setting, which, on the one hand, form a firm fit with the plastic End plate allowed and on the other hand a sufficient oil and / or fuel resistance, a considerable cost savings compared to comparable previously known Executions possible.

Zur Durchführung geeignete Silikonkautschuke sind als Handelsprodukte von auf die Herstellung dieser Produkte spezialisierten Herstellerfirmen aus der chemischen Industrie erhältlich. Ein Beispiel für ein an eine Polyamid-Endscheibe anzuformendes, das heißt insbesondere anzuspritzenden, Silikonkautschuk-Handelsprodukt ist LIM-90/70 GE-Bayer. Die erforderlichen Adhäsions-Additive für ein festes Anformen an eine Polyamid-Endscheibe werden von der Herstellerfirma dem Anwendungs-Anforderungsprofil entsprechend in an sich bekannter Weise ausgewählt. Suitable silicone rubbers are as Commercial products from on the manufacture of these products specialized manufacturers from the chemical industry available. An example of a on a polyamide end plate to be molded, that is to say in particular to be molded, Commercial silicone rubber product is LIM-90/70 GE-Bayer. The required adhesion additives for a firm molding a polyamide end plate are made by the manufacturer Application requirement profile accordingly in itself selected in a known manner.

Ein nachstehend noch näher erläutertes Ausführungsbeispiel ist in der Zeichnung dargestellt. An embodiment explained in more detail below is shown in the drawing.

Es zeigt It shows

Fig. 1 einen Ausschnitt einer ringförmigen Endscheibe an einem Ringfilter. Fig. 1 shows a section of an annular end plate on a ring filter.

Eine ringförmige Endscheibe 1 aus Polyamid-Material ist mit einer Stirnseite eines zu einem Ringfilter gefalteten Bahnenmaterials 2 dicht verbunden. Die dichte Verbindung ist dadurch gegeben, dass die Stirnkanten des Bahnenmaterials 2 in das Endscheiben-Material einplastifziert sind, wozu das Endscheibenmaterial in dem für die Einplastifizierung vorgesehenen Bereich durch kurzzeitige Erwärmung in einen plastischen Zustand versetzt wird. An annular end disk 1 made of polyamide material is tightly connected to an end face of a sheet material 2 folded into a ring filter. The tight connection is provided in that the end edges of the sheet material 2 material end discs are einplastifziert in that for which the Endscheibenmaterial is placed in the space reserved for the Einplastifizierung area by brief heating to a plastic state.

An der axialen Außenseite ist radial innen auf der Endscheibe 1 ein radial dichtender Dichtring 3 aus Silikonkautschuk vorgesehen. Der Silikonkautschuk ist mit Adhäsions-Additiven für eine feste Verbindung gegenüber der Polyamid-Endscheibe in an sich bekannter Weise ausgerüstet. Radial außen legt der Dichtring 3 an einem axial von der Endscheibe 1 abragenden Ringbund 4 an. Der Dichtring 3 ist in einer Spritzgussform an das Material der bereits fertig vorliegenden Endscheibe 1 angespritzt. Insbesondere durch eine auf Polyamid als Endscheibenmaterial eingestellte Zugabe an Adhäsions- Additiven zu dem Silikonkautschuk, beispielsweise der Handelsmarke LIM-90/70 GE-Bayer, ist die erforderliche feste Verbindung zwischen Dichtring und Endscheibe absolut sicher gewährleistet. On the axial outside, a radially sealing sealing ring 3 made of silicone rubber is provided radially on the inside of the end plate 1 . The silicone rubber is equipped with adhesion additives for a firm connection to the polyamide end plate in a manner known per se. The sealing ring 3 rests radially on the outside on an annular collar 4 projecting axially from the end disk 1 . The sealing ring 3 is injection molded in an injection mold onto the material of the end disc 1 that is already finished. In particular, the addition of adhesive additives to the silicone rubber, for example the trademark LIM-90/70 GE-Bayer, which is set to polyamide as the end plate material, guarantees the required firm connection between the sealing ring and the end plate.
