Abstract
(DE)
Die vorliegende Erfindung betrifft ein Filtergerät (1) zum Filtern flüssiger Brennstoffe für Brennkraftmaschinen, insbesondere für große Kolbenmotoren, wie zum Beispiel Schiffsdieselmotoren, umfassend eine Filtereinrichtung (2), die zumindest einen Filterkörper aufweist, der in einem Filterraum einen Rohraum von einem Reinraum trennt, eine Rückspüleinrichtung zum Rückspülen des Filterkörpers mit gereinigtem Brennstoff oder Fremdmedium und eine Ausgleichseinrichtung (4), die einen Kolben aufweist, der in einem mit dem Reinraum kommunizierend verbundenen Zylinderraum hubverstellbar angeordnet ist. Eine kompakte und preiswerte Bauform lässt sich erzielen, wenn ein Gehäuse (5) in einem integralen Korpus (27) den Filterraum und den Zylinderraum enthält.
(EN)
The present invention relates to a filter device (1) for filtering liquid fuels for internal combustion engines, in particular for large piston engines, such as marine diesel engines, comprising a filter apparatus (2) that has at least one filter body that separates an uncleaned chamber from a clean chamber in a filter chamber, a backwash device for backwashing the filter body with cleaned fuel or a foreign medium, and a compensating device (4) that has a piston that is arranged in a stroke-adjustable manner in a cylinder chamber that is connected in a communicating manner to the clean chamber. A compact and inexpensive design can be achieved if a housing (5) contains the filter chamber and the cylinder chamber in an integral body (27).
(FR)
La présente invention porte sur un appareil filtrant (1) pour filtrer des combustibles liquides pour les moteurs à combustion interne, en particulier pour des moteurs à piston de grande taille, comme par exemple des moteurs diesel de navire. Cet appareil comprend un dispositif filtrant (2) qui comporte au moins un corps de filtre, lequel sépare, dans un espace de filtration, un espace non purifié d'un espace purifié, un dispositif de rinçage à contre-courant pour le rinçage à contre-courant du corps de filtre par du combustible purifié ou un milieu étranger et un dispositif d'équilibrage (4) qui comprend un piston, lequel est disposé avec une course réglable dans un espace cylindrique raccordé en communication avec l'espace purifié. Une forme structurale compacte et économique peut être obtenue quand un boîtier (5) contient dans un corps intégral (27) l'espace filtrant et l'espace cylindrique.
