Claims (9)

1. Vorrichtung zur dosierten Entnahme von Flüssigkeit aus einem Flüssigkeitsbehälter, aufweisend ein volumenveränderliches Dosier­ lumen, eine vom Behälter zum Dosierlumen führende, mit einem Saugventil versehene Saugleitung und eine mit dem Dosierlumen in Verbindung stehende, mit einem Druckventil versehene und mittels eines Entnahmeventils verschließbare Entnahmeleitung, gekennzeichnet durch eine mittels eines weiteren Ventils verschließbare, stromaufwärts des Druckventils beginnende, vom Dosierlumen in das Behälterlumen füh­ rende weitere Leitung (11).1.Device for the dosed removal of liquid from a liquid container, comprising a variable-volume dosing lumen, a suction line leading from the container to the dosing lumen, provided with a suction valve, and a discharge line connected to the dosing lumen, provided with a pressure valve and closable by means of a removal valve, characterized by a further line ( 11 ) which can be closed by means of a further valve and starts upstream of the pressure valve and leads from the metering lumen into the container lumen. 2. Entnahmevorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die weitere Leitung (11) ein Rückschlagventil aufweist.2. Removal device according to claim 1, characterized in that the further line ( 11 ) has a check valve. 3. Entnahmevorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die weitere Leitung (11) mittelbar oder unmittelbar unterhalb des Behälterflüssigkeitsspiegels endet. 3. Removal device according to claim 1 or 2, characterized in that the further line ( 11 ) ends indirectly or immediately below the container liquid level. 4. Entnahmevorrichtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass Entnahmeleitung (9) und weitere Leitung (11) zumindest ab­ schnittsweise miteinander verbindbar sind.4. Removal device according to one of claims 1 to 3, characterized in that the removal line ( 9 ) and further line ( 11 ) can be connected to one another at least in sections. 5. Entnahmevorrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die Betätigung von Entnahmeventil und weiterem Ventil kine­ matisch gekoppelt erfolgt.5. Removal device according to one of claims 1 to 4, characterized, that the actuation of the tapping valve and further valve kine matically coupled. 6. Entnahmevorrichtung nach Anspruch 5, dadurch gekennzeichnet, dass die Hähne von Entnahmeventil und weiterem Ventil durch eine gemeinsame, vorzugsweise einstückige Ventilwelle (10) gebildet werden.6. Extraction device according to claim 5, characterized in that the taps of the extraction valve and further valve are formed by a common, preferably one-piece valve shaft ( 10 ). 7. Entnahmevorrichtung nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, dass zumindest Bereiche der Entnahmeleitung (9) durch den Hahn des Entnahmeventils bzw. durch die Ventilwelle (10) gebildet werden.7. Extraction device according to one of claims 1 to 6, characterized in that at least regions of the extraction line ( 9 ) are formed by the tap of the extraction valve or by the valve shaft ( 10 ). 8. Entnahmevorrichtung nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, dass das Entnahmeventil als Mehrwegeventil ausgebildet ist, das eine Stellung aufweist, in der die in der Entnahmeleitung (9) enthaltene Flüssigkeitsmenge in den Flüssigkeitsbehälter (2) zurückleitbar ist. 8. Removal device according to one of claims 1 to 7, characterized in that the removal valve is designed as a multi-way valve, which has a position in which the amount of liquid contained in the removal line ( 9 ) can be returned to the liquid container ( 2 ). 9. Entnahmevorrichtung nach einem der Ansprüche 1 bis 8, dadurch gekennzeichnet, dass ein Ventilhahn bzw. die Ventilwelle (10) eine zumindest teil­ weise umlaufende Ringnut (15) aufweist, die mit einer vorzugsweise stirnseitig am Ventilhahn bzw. an der Ventilwelle (10) angeordneten Lüftungsöffnung (14) sowie über einen Verbindungskanal mit dem Behälterluftraum (12) in Verbindung steht.9. Removal device according to one of claims 1 to 8, characterized in that a valve tap or the valve shaft ( 10 ) has an at least partially circumferential annular groove ( 15 ), which preferably has an end face on the valve tap or on the valve shaft ( 10 ) arranged ventilation opening ( 14 ) and via a connecting channel with the container air space ( 12 ) in connection.
