Abstract:
The invention relates to a liquid reservoir (1), in particular for an aqueous urea solution, comprising a buffer storage means (2) arranged on the bottom of the liquid reservoir (1) in the installation position, a liquid delivery unit (3), at least one, preferably a plurality of, first filter elements (4) arranged on the bottom in the installation position outside the buffer storage means (2), each of which first filter elements is connected to the liquid delivery unit (3) via a liquid line (5), the first filter elements (4) being constructed such that the filter fabric of the first filter elements (4) is permeable to the liquid located in the liquid reservoir (1) and impermeable to air, a second filter element (6) being arranged between the interior of the buffer storage means (2) and the liquid delivery unit (3), which second filter element is constructed such that the filter fabric of the second filter element (6) is permeable to the liquid located in the liquid reservoir (1) and impermeable to air, the breakthrough pressure of the second filter element (6), at which air is delivered through the filter element, being greater than the breakthrough pressure of the first filter elements (4), furthermore comprising a first valve (7) between the liquid delivery unit (3) and the first filter elements (4), the opening pressure of the first valve (7) being smaller than the breakthrough pressure of the second filter element (6).
Abstract:
Die Erfindung betrifft einen Reduktionsmittelbehälter (1) für Kraftfahrzeuge mit wenigstens einem mit einer Einfüllöffnung (4) versehenen Einfüllrohr (3), mit wenigstens einer Einrichtung zur Befüllentlüftung und mit Mitteln zur Füllstandsbegrenzung bei der Befüllung sowie mit Mitteln zum Verschließen der Befüllentlüftung bei oder nach Erreichen des maximalen Füllstandes, wobei die Einrichtung zur Befüllentlüftung wenigstens eine Befüllentlüftungsleitung (7) umfasst, die sich zumindest abschnittsweise oberhalb des maximalen Füllstandes im Einfüllrohr (3) und/oder im Behälter erstreckt.
Abstract:
The invention relates to a liquid reservoir (1) for urea solution having at least one discharge line, which is embodied as an intake line, and which communicates with the reservoir volume via at least one filter element (4). The filter element (4) comprises at least one filter fabric (10) and/or a non-woven filter material, which when wetted prevents an aspiration of air. A distinguishing feature of the liquid reservoir according to the invention is that the filter element (4) comprises a housing (8), which defines an accumulator volume, which can be at least partially drained when the reservoir volume is empty.
Abstract:
The invention relates to a thermoplastic tank (1) with at least one insert part which is provided in the interior of the tank (1) and is inserted into the tank (1) through an opening (3) in a tank wall (2) and is sealed against a peripheral flange (4) provided in the region of the opening (3). The flange (4) is formed integrally with the tank wall (2) and is countersunk therein.
Abstract:
The invention relates to a pressure equalizing valve (5) for a fuel tank or secondary fluid tank on a motor vehicle, comprising at least one valve housing (10), at least one valve body movably arranged in the valve housing (10), at least one venting opening on the tank side and on the connection side or on the atmosphere side, which form a venting path (16) which may be opened or closed by the valve body depending on the position of the tank, when a predetermined transverse force is exceeded relative to a normal force which holds the valve body in a valve seat, the valve body being able to be lifted or deflected from the valve seat and thus opening the venting path (16) and when falling below said transverse force automatically adopting again the position closing the venting path (16). The valve body is configured as a ball (15) and arranged so that when pressure prevails on the tank side, said valve body is held in the valve seat.

Abstract:
Die Erfindung betrifft einen Reduktionsmittelbehälter 1 zur Aufnahme eines flüssigen Reduktionsmittels als so genannter SCR-Behälter. Der SCR-Behälter umfasst wenigstens eine Einrichtung zur Entlüftung des Behälters, die mit wenigstens einem Druckausgleichselement verschlossen ist, welches einen Gasaustausch zulässt, den Behälter jedoch flüssigkeitsdicht verschließt. Der Reduktionsmittelbehälter (1) umfasst weiterhin wenigstens eine Entlüftungsleitung (5), die mit dem Druckausgleichselement kommuniziert, wobei die Entlüftungsleitung (5) in Einbaulage des Behälters wenigstens bis oberhalb des maximal zulässigen Watniveaus geführt ist. Die Entlüftungsleitung (5) weist wenigstens einen ersten abschüssigen Leitungsabschnitt (5a) auf, der sich in einen zweiten steigenden Leitungsabschnitt (5b) zur Entlüftung und einen dritten fallenden Leitungsabschnitt (5c) zur schwerkraftbedingten Kondensatdrainage verzweigt.
Abstract:
The invention relates to a ventilating device (2) for liquid containers (1), in particular for liquid containers (1) for an aqueous urea solution, comprising a housing (3) which can be mounted at an opening of the liquid container (1) and has a first opening (4) to the liquid container (1) and a second opening (5) to the surroundings of the liquid container (1), a diaphragm (6) which is arranged within the housing (3), is permeable to air, is impermeable to liquid and is configured in such a way that a deformation of the diaphragm (6) takes place by a pressure change in the liquid container (1), as a result of which the volume within the housing (3) within the diaphragm (6) changes, with the result that the displaced volume leaves the housing (3) via the second opening (5) to the surroundings of the liquid container (1). Furthermore, the invention relates to a liquid container (1) having a ventilating device (2) according to the invention.
