K PATENTAMT.K PATENT OFFICE.
Bei den bisher bekannten Handpumpenfiltern, mittels deren man auf Reisen in den Tropen oder solchen Gegenden, in denen reines Trinkwasser nicht ohne weiteres erhältlich ist, letzteres aus jedem beliebigen Wasserlauf beschaffen kann, hat man die zur Schonung und Erhaltung des Filter Zylinders sehr viel beitragenden Windkessel meist fortgelassen, um den ganzen Filter kleiner und leichter, alsoWith the previously known hand pump filters, by means of which one can travel in the Tropics or areas where pure drinking water is not readily available, the latter can be obtained from any watercourse, one has to protect and Preservation of the filter cylinder very much contributing air chamber mostly omitted to the whole filter smaller and lighter, so
ίο transportfähiger zu machen. Da nun aber durch die Benutzung eines Windkessels in Verbindung mit Handpumpenfiltern der auf den Filterzylinder wirkende Druck der Wassersäule gleichmäßiger verteilt wird, so erscheint die Beibehaltung eines solchen Windkessels äußerst wünschenswert.ίο to make it more transportable. But now by using an air chamber in conjunction with the hand pump filters the pressure of the water column acting on the filter cylinder is distributed more evenly, it appears the retention of such an air chamber is highly desirable.
Mit der vorliegenden Neuerung wird nun bezweckt, die Benutzung eines Windkessels in Verbindung mit einem Handpumpenfilter in der Weise zu ermöglichen, daß die Abmessungen eines solchen Reisefilters nur ganz unwesentlich vergrößert werden.With the present innovation the aim is now to use an air chamber in Connection to a hand pump filter in such a way that the dimensions allow of such a travel filter can only be increased insignificantly.
Zu diesem Zwecke wird der die Filterkerze enthaltende Teil des Filters innerhalb des Windkessels angeordnet.For this purpose, the part of the filter containing the filter candle is inside the Arranged air chamber.
In der Zeichnung ist ein Ausführungsbeispiel der Neuerung in der Seitenansicht teilweise im Schnitt veranschaulicht.In the drawing, an embodiment of the innovation is partially in side view illustrated in section.
In dem eigentlichen Filtergehäuse α ist die Filterkerze b zweckmäßig durch ein mit Durchbrechungen versehenes Versteifungsröhrchen c befestigt. Das Filtergehäuse α ist oben mit einem entsprechenden Anschluß d für die Ableitung des Reinwassers und unten mit einem anderen Anschluß β für die Zuführung des Roh wassers versehen. Außerdem steht das Filtergehäuse α an seinem unteren Ende durch eine Kammer i und ein Verbindungsrohr / mit dem Zylinder einer Handpumpe g in Verbindung. In the actual filter housing α , the filter candle b is expediently attached by a stiffening tube c provided with perforations. The filter housing α is provided above with a corresponding connection d for the discharge of the pure water and below with another connection β for the supply of raw water. In addition, the filter housing α is at its lower end through a chamber i and a connecting pipe / with the cylinder of a hand pump g in connection.
Außen ist gemäß der Erfindung das Filtergehäuse α annähernd auf seiner ganzen Länge > in einiger Entfernung von einem Mantel h umgeben, der an seinem unteren Ende an das Filtergehäuse durch Öffnungen k angeschlossen ist und den Windkessel der Vorrichtung bildet.On the outside, according to the invention, the filter housing α is surrounded almost over its entire length> at some distance by a jacket h which is connected at its lower end to the filter housing through openings k and forms the air chamber of the device.
Bei der Benutzung wird der Filterapparat durch einen Anschluß an den Stutzen β mit der Rohwasserquelle verbunden und die Pumpe g bedient. Beim Heben des Pumpenkolbens strömt das Rohwasser durch den Stutzen β über das vorteilhaft als Kugelventil ausgebildete Rückschlagventil I in die Kammer i und von dort durch das Verbindungsrohr f in den Pumpenzylinder. Bei Abwärtsbewegung des Pumpenkolbens wird das Rohwasser aus dem Pumpenzylinder durch die Verbindung f und Kammer i über das zweite Rückschlagventil m in das Filtergehäuse α hineingedrückt. Hierbei werden Ungleichmäßigkeiten in dem auf die Filterkerze b zur Wirkung kommenden Druck durch die in dem umgebenden Windkessel h befindliche Luft beseitigt.In use, the filter apparatus is connected to the raw water source by a connection to the nozzle β and the pump g is operated. When the pump piston is lifted, the raw water flows through the nozzle β via the check valve I, which is advantageously designed as a ball valve, into the chamber i and from there through the connecting pipe f into the pump cylinder. When the pump piston moves downwards, the raw water is pressed from the pump cylinder through the connection f and chamber i via the second check valve m into the filter housing α . In this case, irregularities in the pressure acting on the filter candle b are eliminated by the air in the surrounding air chamber h.
