Tiivistetty suodatinCondensed filter
Selitys Tekniikan ala 5 Keksintö liittyy suodatustekniikkaan ja koskee suodatinta, jossa on pitkänomainen suodatinkammio ja siinä vaihdettava suodatinelementti, jossa on sylinterimäinen suodatuspinta. Kammion toisessa päässä on yhde elementin sisäpuolelle ja sylinterimäinen nippa, johon elementti on tiivistetty. Lisäksi kammioon on toinen yhde.TECHNICAL FIELD The invention relates to a filtering technique and relates to a filter having an elongate filter chamber and a replaceable filter element having a cylindrical filtering surface. At one end of the chamber, there is one inside the element and a cylindrical nipple into which the element is sealed. In addition, another chamber is provided in the chamber.
Tekniikan tausta 10 Edellä mainitunlaisissa tunnetuissa suodattimissa suodatinelementti on tiivistetty nippaan tavanomaisella O-rengastiivisteellä. Esimerkiksi julkaisussa US 6 099 726 esitetään eräs tällainen suodatin. Siinä nippa on suodatinkammion alapäässä ja suodatinelementin alakannessa on putki, joka asettuu nipan ulkopinnalle. Putken sisäpinnalla on pyöreä ura, jossa on O-rengastiiviste.BACKGROUND ART In the prior art filters of the type mentioned above, the filter element is sealed to the nipple by a conventional O-ring seal. For example, US 6,099,726 discloses one such filter. It has a nipple at the lower end of the filter chamber and a tube on the lower lid of the filter element which rests on the outer surface of the nipple. The inner surface of the tube has a circular groove with an O-ring seal.
15 Keksinnön yleinen kuvaus15 General Description of the Invention
Se mitä patentilla halutaan suojata, esitetään patenttivaatimuksissa.What the patent is intended to protect is set forth in the claims.
Keksinnön mukaisessa suodattimessa suodatinelementti on tiivistetty nippaan rengastiivisteellä, jolloin joko rengastiivisteen tason normaali muodostaa terävän kulman elementin akselin kanssa tai sen vastinkappaleen, jossa rengastiiviste ei 20 ole, pään määrittämän tason normaali muodostaa terävän kulman elementin akseli Iin kanssa. Kulma on edullisesti 1 - 60 °, edullisemmin 5 - 45 °, edullisimmin 10 - ^ 20 °. Näin elementin paikalleen asettamiseen tarvittava voima on pienempi kuin i o tavanomaista O-rengastiivistystä käytettäessä. Elementti saadaan paikalleen sula- i ^ vasti liuuttaen, eikä tarvita voimakasta äkkiliikettä. Tiiviste ei myöskään irtoa uras- x 25 taan elementtiä paikalleen työnnettäessä niin helposti kuin tavanomaista tiivistystä käytettäessä. Vastaavasti myös elementin poisottaminen on helpompaa. Keksinet nön ansiosta voidaan käyttää tiukempaa ja siten myös varmempaa tiivistystä.In the filter of the invention, the filter element is sealed to the nipple by an O-ring, whereby either the normal level of the O-ring forms an acute angle with the axis of the element or the normal The angle is preferably 1 to 60 °, more preferably 5 to 45 °, most preferably 10 to 20 °. Thus, the force required to insert the element is less than with conventional O-ring sealing. The element is obtained by melt dissolution and no strong sudden movement is required. Also, the gasket does not come loose when inserting the element as easily as when using a conventional gasket. Correspondingly, removing the element is also easier. Thanks to the invention, a tighter and thus more secure seal can be used.
tn o 5 Parhaiten rengastiivisteen normaali muodostaa terävän kulman elementin akselin kanssa.tn o 5 Ideally, the normal ring seal forms an acute angle with the axis of the element.

Nippa on suodatinkammiossa oleva sylinterimäinen putki. Parhaiten se ulottuu kammion sisäpuolelle. Suodatinelementissä on päätykansi, jossa on nippaan tiivistettävä sylinterimäinen vastinputki. Parhaiten vastinputki on samaa kappaletta päätykannen kanssa. Parhaiten vastinputki tulee nipan ulkopinnalle. Parhaiten tii-5 viste on tällöin vastinputken pinnalla olevassa urassa. Vaihtoehtoisesti vastinputki voidaan sovittaa nipan sisäpinnalle. Tällöinkin tiiviste on parhaiten vastinputken pinnalla olevassa urassa.The nipple is a cylindrical tube in the filter chamber. Best of all, it extends inside the chamber. The filter element has an end cap having a cylindrical counter tube to be sealed in a nipple. Ideally, the counter tube is the same piece as the end cap. The counter tube is best placed on the outside of the nipple. In this case, the tie-5 braid is preferably in the groove on the surface of the counter tube. Alternatively, the counter tube may be fitted to the inner surface of the nipple. Here too, the seal is best located in the groove on the surface of the counter tube.
Parhaiten suodatinkammiossa on avattava kansi, jonka kautta suodatinelementit vaihdetaan.Ideally, the filter chamber has a flap opening through which the filter elements are replaced.
10 Suodatinelementin suodatuspinta voi muodostua erityisesti rypytetystä suodatin-kankaasta. Elementissä tukirakenteena reiitetty putki, yläpäässä yläkansi ja alapäässä alakansi.10 The filtering surface of the filter element may consist of a particularly woven filter cloth. The element has a perforated tube with a support structure, a top cover at the top and a bottom cover at the bottom.
Suodatinelementtejä ja vastaavasti nippoja voi olla suodatinkammiossa useampiakin.There may be more than one filter element and nipples in the filter chamber, respectively.
15 Myös suodatinelementin nipan vastakkaisessa päässä tulo- ja poistopuoli voidaan erottaa toisistaan vastaavanlaisella vinolla rengastiivistyksellä kuin nipan puoleisessa päässä.Also, at the opposite end of the nipple of the filter element, the inlet and outlet sides can be separated by a similar oblique ring seal as at the nipple end.
Parhaiten suodatettava neste johdetaan suodatuspinnan läpi ulkopuolelta sisäpuolelle, jolloin suodatettu neste poistetaan nipan kautta.The liquid to be filtered is preferably passed through the filter surface from the outside to the inside, whereby the filtered liquid is discharged through the nipple.
20 Suodatinta voidaan käyttää niin nesteiden kuin kaasujenkin suodattamiseen. Suodatettava neste voi olla esimerkiksi voitelunestettä, polttonestettä, hydraulinestettä tai vettä.20 The filter can be used to filter both liquids and gases. The fluid to be filtered may be, for example, lubricating fluid, fuel fluid, hydraulic fluid or water.
