In Fig.2 ist eine Filtervorrichtung gemäss der Erfindung dargestellt, die ein zylindrisches Gehäuse Io aufweist, das mit einem radialen Einlass 11 und einem axialen Auslass 12 versehen ist.In Figure 2, a filter device according to the invention is shown, which has a cylindrical housing Io, which with a radial inlet 11 and an axial outlet 12 are provided is.
Ein zylindrisches Filterelement 14 ist in dem Gehäuse angeordnet, und das Ende davon steht in abdichtender Berührung mit einem axialen Vorsprung 15 mittels eines O-Rings 16, der die Dichtung bildet.A cylindrical filter element 14 is disposed in the housing and the end thereof is in sealing contact with an axial projection 15 by means of an O-ring 16 which forms the seal.
Das andere Ende des Filterelements 14 ist von gleicher Konstruktion und bildet eine Dichtung mit einem Axialvorsprung 17 auf der Abdeckung mittels eines O-Ringes 18, der wieder die tatsächliche Dichtung bildet. The other end of the filter element 14 is of the same construction and forms a seal with an axial projection 17 on the cover by means of an O-ring 18 which again forms the actual seal.

Der Vorsprung 17 umfasst eine öffnung 19, in der ein Bypassventil 2o angeordnet ist. Das Bypassventil 2o wird federnd nachgiebig nach aussen und oben gemäss Fig.1 gedrängt durch eine Schraubenfeder 21, die zwischen dem Ventil 2o und dem anderen Ende des Filterelements angeordnet ist, wobei die Feder die zusätzliche Funktion übernimmt, das Filterelement gegen die Schulter 22 des Filters zu drücken. Der Axialvorsprung 17 umfasst radiale öffnungen 23, die eine Flüssigkeitsverbindung zwischen dem Einlass 11 und dem anderen Ende des Bypassventils 2o herstellen.The projection 17 comprises an opening 19 in which a bypass valve 2o is arranged. The bypass valve 2o is resiliently pushed outwards and upwards according to FIG a coil spring 21 disposed between the valve 2o and the other end of the filter element, the spring takes on the additional function of pressing the filter element against the shoulder 22 of the filter. The axial projection 17 comprises radial openings 23 which provide a fluid connection Establish between the inlet 11 and the other end of the bypass valve 2o.
Wenn der Filter 14 schmutzig wird, bewegt sich das Bypassventil 2o axial nach innen,und das Ventil öffnet sich, so dass Flüssigkeit über die Bypassleitung direkt zum Auslass 12 gelangen kann. Spezielle Anzeigeeinrichtungen bilden kein Teil dieser vorliegenden Erfindung.When the filter 14 gets dirty, the bypass valve 2o moves axially inward and the valve opens so that Liquid via the bypass line directly to outlet 12 can get. Special display devices do not form part of this present invention.
Eine Feder 3o umgibt das Filterelement und ist zwischen der Abdeckung und dem Gehäuse angeordnet. Wie schematisch in Fig.2 dargestellt ist, wird die Feder 3© magnetisiert in aufeinanderfolgenden Nord-Süd-Polen längs ihrer Länge, um Metallteilchen, die sich in dem Fluidum befinden und durch den Filter gelangen können, anzusammeln.A spring 3o surrounds the filter element and is between the Cover and the housing arranged. As shown schematically in Fig.2, the spring 3 © is magnetized in successive North-South poles along their length to avoid metal particles that are in the fluid and pass through the filter can accumulate.
Die Feder J>o ist vorzugsweise aus leicht magnetisierbarem Material hergestellt, wie beispielsweise Cunife I, das eine Zusammensetzung aus 6o % Kupfer, 2o % Nickel und 2o % Eisen aufweist. Dieses Material ist biegsam und kann kalt bearbeitetThe spring J> o is preferably made of an easily magnetizable material, such as Cunife I, for example, which has a composition of 60 % copper, 20 % nickel and 20 % iron. This material is flexible and can be cold worked

Die Feder befindet sich auf einem Kern 36, der zwischen Backen 31a, ^Ib angeordnet ist,und die Backen bewirken, dass die Feder ^ festgeklemmt wird. Die Backen 31a, 31t) kommen mit im Abstand liegenden Umfangstellen der Feder in Berührung. Jede Backe 31 bildet einen Pol einer magnetischen Spule 33> die erregt wird von einer Gleichstromquelle 3^· Das Backen- oder Polstück 31t) ist verstellbar mittels einer Schraube 35* um eine Anpassung beim Einsetzen und ein Entfernen der Feder zu ermöglichen. In der Magnetisierungsstelle ruht die Spule auf einer Platte 37 aus nichtmagnetischem Material.According to the invention, the spring J> o is magnetized using a device shown in FIGS. The spring is located on a core 36 which is arranged between jaws 31a, ^ Ib, and the jaws cause the spring ^ to be clamped. The jaws 31a, 31t) come into contact with spaced circumferential locations of the spring. Each jaw 31 forms a pole of a magnetic coil 33> which is excited by a direct current source 3 ^ · The jaw or pole piece 31t) is adjustable by means of a screw 35 * to allow adjustment when inserting and removing the spring. In the magnetization point, the coil rests on a plate 37 made of non-magnetic material.
