Description

Gegenstand der Erfindung ist ein Flüssigkeitsfilter mit Dreiweghahn, insbesondere ein Filter für Brennstoffe für Kraftwagen und Motoren, das die bisherigen Mängel dieser Filter beseitigt. Schwierigkeiten im Gebrauch ergaben sich einmal beim Filter selbst, indem sich das nur angeschraubte Filter zu leicht löste, so daß der Brennstoff ungereinigt in den Motor kam. Durch eine starke Schrauhenfeder wird das Filter fest gegen seinen Sitz gedrückt, kann sich also nie lockern. Zweitens wurde der Dreiweghahn dadurch schnell undicht, daß durch die Fernhetätigung seitliche Kräfte das Küken aus seiner Lage zur Seite drückte, wodurch die Gummidichtung einseitig belastet wurde und dadurch schlecht dichtete. Ahh. I zeigt einen Schnitt,4-B der Abb. 2, die einen Vertikalschnitt darstellt. Das Gehäuses ist durch Doppelmutter 24 mit Links- und Rechtsgewinde an den Brennstoffl>ehälter angeschlossen. Die Rohrleitung 19 ragt in bekannter Weise bis zu einer gewissen Tiefe in den Behälter. Sobald der Behälter bis an die t)ffnung des Rohres 19 leergelaufen ist, wird der Motor infolgedessen stehenbleiben, bis der Dreiweghahn 10 auf das kurze Rohr 20 umgestellt wird. The invention relates to a liquid filter with a three-way valve, in particular, a filter for fuels for automobiles and engines that the previous Defects of this filter eliminated. Difficulties in use arose once with the filter itself, as the screwed-on filter came off too easily, like this that the fuel got into the engine uncleaned. With a strong helical spring if the filter is pressed firmly against its seat, it can never loosen. Secondly the three-way tap was quickly leaking because the remote control on the side Forces the chick pushed out of its position to one side, causing the rubber seal to one-sided was burdened and thus wrote poorly. Ahh. I shows a section, 4-B of the Fig. 2, which is a vertical section. The housing is by double nut 24 connected to the fuel container with left and right threads. the Pipeline 19 protrudes in a known manner to a certain depth in the container. As soon as the container has run empty to the opening of the pipe 19, the As a result, the engine will stop until the three-way valve 10 is on the short pipe 20 is switched.

Zwischen dem Gehäuse 1, das die Bohrungen für die Rohrleitungen der drei Rohre I9, 20 und 1 trägt, und dem Küken lo, das durch zwei Schräglocher je nach der Stellung Rohr 19 oder 20 mit dem Eintrittsrohr 1l im Innern des Filters iS verl>indet liegt die Gummidichtung 16, deren Bohrungen mit denen im Gehäuse 1 übereinstimmen müssen. Die Gummidichtung wird zu diesem Zwecke durch den Stift 23 gegen Drehung gesichert.Between the housing 1, which has the holes for the pipelines of the three tubes I9, 20 and 1 carries, and the chick lo, which through two oblique holes each after the position pipe 19 or 20 with the inlet pipe 1l inside the filter The rubber seal 16 is left, its bores with those in the housing 1 must match. The rubber seal is for this purpose through the pin 23 secured against rotation.

Bisher war diese Drehungssicherung bei diesen lähnen unbekannt. Es hat sich ferner herausgestellt, daß die Scheibe 16 besser dichtet, wenn man das Gehäuse I da, wo die Dichtung aufliegt, ganz leicht wölbt, um zu erreichen, daß die Dichtung 16 am Rande stärker gepreßt wird. Von besonderer Wichtigkeit ist es, daß die Dichtung nicht einseitig stärker gedrückt wird. Dies wird beispielsweise durch die beiden gut passenden Lagerbüchsen 8 und g erreicht, die jedes Kil)pen des Küken 10 verhindern. Zwischen den Lagerl)üchsen befindet sich die Druckfeder 2, die das Küken gegen das Gehäuse drückt. Sprengring 22 hält die Feder unter Spannung. Ein Anschlagstift 21 im Küken begrenzt die Einstellung des Kükens, indem er gegen den Stift 23 stößt. Das Filter 18 ist mit seinem Deckel 5 und dem Zulaufrohr 11 fest verbunden.Up to now, this anti-rotation device was unknown on these lära. It has also been found that the disk 16 seals better if you do that Housing I arches very slightly where the seal rests in order to achieve that the seal 16 is pressed harder at the edge. It is of particular importance that the seal is not pressed harder on one side. This is for example thanks to the two well-fitting bearing bushes 8 and g, which every kilo of the chick 10 prevent. The compression spring is located between the bearing sleeves 2, which presses the chick against the housing. Snap ring 22 keeps the spring under tension. A stop pin 21 in the plug limits the adjustment of the plug by acting against it the pin 23 pushes. The filter 18 is with its cover 5 and the inlet pipe 11 firmly connected.

Ein Klemmring 15 hält das Filter fest, wenn man die Glocke 4 abnimmt, damit es nicht von selbst herunterfällt, sondern eine kleine Kraft zum Abziehen erfordert. Die Sehraul)enfeder 3 drückt das Filter gegen seinen Sitz 7. Ein Loslösen ist dadurch unmöglich. Ein umklappbarer Bügel 13 hält die Schraube 14. welche die Glocke 4 andrückt.A clamping ring 15 holds the filter in place when the bell 4 is removed, so that it doesn't fall off by itself, but a little force to pull it off requires. The vision spring 3 presses the filter against its seat 7. A loosening is therefore impossible. A foldable bracket 13 holds the screw 14 which the Bell 4 presses.
