Abstract
Description
Schwimmerventil Float valve
In der Patentanmeldung P 3321 453.0, auf die hier vollinhaltlich Bezug genommen wird, wurde ein Schwimmerventil für einen WC-Spülkasten beschrieben, das durch einen Permanentmagneten zusätzlich so gesteuert wird, daß das Ventil während des gesamten Füllvorgangs geöffnet bleibt und sich erst bei vollstandig gefülltem Spülkasten ziemlich schnell schließt. Dies wird dadurch erreicht, daß der Schwimmer mit jilife der Anziehungskraft eines Permanentmagneten und dessen magnetisierbarem Gegenstück entgegen der Auftriebskraft solange niedergehalten wird, bis die Auftriebskraft des Schwimmers mit steigendem Wasserspiegel diese Anziehungskraft überwindet, sodaß die Magnetlcupplung getrennt wirdJund sich das Ventil schließen kann. In the patent application P 3321 453.0, which is here in full Reference is made to a float valve for a toilet cistern has been described, which is also controlled by a permanent magnet so that the valve during the entire filling process remains open and only when it is completely filled Cistern closes pretty quickly. This is achieved by the swimmer with jilife the attraction of a permanent magnet and its magnetizable Counterpart against the buoyancy force is held down until the buoyancy force the swimmer overcomes this attraction as the water level rises, so that the magnetic coupling is disconnected and the valve can close.
Wie Experimente zeigen, besteht bei dieser Konstruktion das Risiko, daß sich das Ventil so rasch schließt, daß es zu einem Rückschlag kommt.As experiments show, there is a risk with this construction that the valve closes so quickly that there is a kickback.
Aufgabe der vorliegenden Erfindung ist es, Vorschläge offenzulegen, durch welche dieser Mangel beseitigt werden kann. The object of the present invention is to disclose proposals through which this deficiency can be eliminated.
Hierzu bietet sich besonders die Ausnutzung von strömungsmechanischen oder magnetischen Dämpfungsverfahren an. For this purpose, the use of fluid mechanics is particularly useful or magnetic damping method.
Um solche strömungsmechanische Kräfte auszunutzen, wird vorgeschlagen, die äußere Form des Schwimmers so zu gestalten, daß sich beim Auftauchen Wirbel bilden und/oder Wassermassen verdrängt werden müssen, sodaß die nach dem Ne»ton'- schen Grundgesetz b = m/K erreichte Beschleunigung des Schwimmers klein bleibt. Möglichkeiten hierzu sind in den Fign. 1 und 2 dargestellt, die einen mit Einbuchtungen oder Ausbuchtungen versehenen Schwimmer 3 zeigen. In order to exploit such fluid mechanical forces, it is proposed that to design the outer shape of the swimmer so that eddies are created when surfacing form and / or water masses have to be displaced so that the ting Basic law b = m / K achieved acceleration of the swimmer remains small. options in this regard are shown in FIGS. 1 and 2 shown, the one with indentations or bulges provided float 3 show.
Zur Verbesserung der Dämpfung wird weiter vorgeschlagen, im Innern des Schwimmers einen Hohlraum 4 vorzuscheder durch Öffnungen 5 mit dem Außenraum verbunden ist, und sich bei eingetauchtem Schwimmer mit Wasser füllt. Durch die Wassermasse in dem Hohlraum vergrößert sich die gegenüber der Auftriebskraft wirksame effektive träge Masse des Schwimmers, sodaß sich die Geschwindigkeit der Auftriebsbewegung verkleinert. To improve the damping, it is also proposed inside of the float vorzuzueder a cavity 4 through openings 5 with the outside space connected, and fills with water when the swimmer is submerged. Through the The mass of water in the cavity increases that which is effective in relation to the buoyancy force effective inertial mass of the swimmer, so that the speed of the buoyancy movement scaled down.
Die enstehende dynamische Zusatzmasse und die Verringerung des Auftriebs sollen in der Ruhestellung verschwinden. Um dies zu gewährleisten sind die Öffnungen 5 so zu gestalten, daß das Wasser während das Auftauchens des Schwimmers aus dem Hohlraum abfließen kann, sodaß in der Endstellung der Wasserspiegel innerhalb und außerhalb des Schwimmers denselben Pegel aufweist. Ein praktisches Ausführungsbeispiel hierzu ist in Fig. 3 gezeichnet. Durch diese Maßnahme kann die Geschwindigkeit des Schließvorgangs in weiten Bereichen variiert und so den Erfordernissen nach Rücksehlagsicherheit und geräuschlosem Schließen angepaßt werden.The resulting dynamic additional mass and the reduction in lift should disappear in the rest position. The openings are used to ensure this 5 to design so that the water during the ascent of the float from the Cavity can flow away, so that in the end position of the water level within and has the same level outside of the float. A practical embodiment this is shown in FIG. 3. This measure can reduce the speed of the Closing process varies in wide areas and thus the requirements for security against backlash and noiseless closing.
Praktisch kann dieser Hohlraum durch eine Kappe realisiert werden, dieJwie in Fig. 3 angedeutet, seitlich auf den Schwimmer aufgesteckt wird. In practice, this cavity can be realized by a cap, dieJas indicated in Fig. 3, is attached to the side of the float.
imine dynamische Zusatzmasse entsteht übrigens auch bei dem in Fig r,ezeichneten Auführunsbeispiel Als Ausführungsbeispiel eines magnetischen Dämpfungsverfahrens wird vorgeschlagen, daß ein Magnet mit T-förmigem Querschnitt in einen torusförmigen eintaucht wie dies Fig. 4 zeigt. Incidentally, imine dynamic additional mass also arises in the case of the one shown in Fig r, shown example As an embodiment of a magnetic Damping method is proposed that a magnet with a T-shaped cross-section immersed in a toroidal shape as shown in FIG.
Einer der beiden Magnete kann hierbei aus magnetisierbarem Material bestehen.One of the two magnets can be made of magnetizable material exist.
