Title
(EN) BACKFLUSHABLE LIQUID FILTER
(FR) FILTRE À LIQUIDE POUVANT ÊTRE RINCÉ À CONTRE-COURANT
Abstract
(EN) The invention relates to a backflushable liquid filter, especially for fuel filtration of an oil burner, with a filter cartridge 6 arranged in a filter housing for separating a liquid inlet E from a filtrate outlet A, and with a backflushing device 20 for the backflushing of the filter cartridge, comprising an operating shaft 21 being rotatable around an axis. In order to create a back¬ flushable liquid filter with good filtration capacity, a plurality of filter candles 7 in the cartridge are arranged on a pitch circle with a perforated plate 8 being associated with the open ends of the filter candles. The operating shaft 21 functions as a flushing passage 23 for fluidic connection of the flushing head 22 to a flushing outlet 17 and has a flushing head 22 being movable as a result of an axial movement of the operating shaft 21 from a neutral position into a flushing position, in which the flushing head 22 butts against the perforated plate. The operating shaft 21 is axially displaceable relative to the flushing head 22 and the fluid connection between flushing head 22 and flushing passage (23) is openable or closable as a result of an axial displacement.
(FR) L'invention concerne un filtre à liquide pouvant être rincé à contre-courant, en particulier pour la filtration de combustible d'un brûleur à huile, avec une cartouche de filtre 6 placée dans un boîtier de filtre pour séparer une entrée de liquide E d'une sortie de filtrat A, et avec un dispositif de rinçage à contre-courant 20 pour le rinçage à contre-courant de la cartouche de filtre, comprenant un arbre d'entraînement 21 qui peut tourner autour d'un axe. Afin de créer un filtre à liquide pouvant être rincé à contre-courant ayant une bonne capacité de filtration, une pluralité de bougies filtrantes 7 dans la cartouche est disposée sur un cercle primitif avec une plaque perforée 8 qui est associée aux extrémités ouvertes des bougies filtrantes. L'arbre d'entraînement 21 fonctionne comme passage de rinçage 23 pour la connexion fluidique de la tête de rinçage 22 à une sortie de rinçage 17 et comprend une tête de rinçage 22 qui est mobile en résultat du mouvement axial de l'arbre d'entraînement 21 entre une position neutre et une position de rinçage, dans laquelle la tête de rinçage 22 s'appuie sur la plaque perforée. L'arbre d'entraînement 21 est mobile axialement par rapport à la tête de rinçage 22 et la connexion fluidique entre la tête de rinçage 22 et le passage de rinçage (23) peut être ouverte ou fermée par un déplacement axial.
