Description
Rasensprenger. Die Erfindung betrifft einen Rasenspren ger, welcher ohne bewegte Teile einen grossen Aktionsradius zu erzielen ermöglicht.
Die in früheren Jahren üblichen, einfach aus einer Sprühdüse mit weitem Sprühkegel bestehenden Rasensprenger besitzen nur einen relativ kleinen Aktionsradius, weil der Druck abfall in einer solchen Sprühdüse so gross ist, dass für das Abschleudern der Tröpfchen nicht mehr viel Energie übrigbleibt. Um grö ssere Aktionsradien zu erhalten, ist man des halb in neuerer Zeit dazu übergegangen, den Wasserstrahl gebündelt aus einer Düse mit niögliclist geringem Druckabfall austreten zu lassen und durch rotierende Ablenkfläclien oder dergleichen im Kreis zu führen.
Hierbei gewinnt man zwar einen wesentlich vergrösser- teti Aktionsradius; aber die Anwendung von rotierenden Teilen führt. zwangläufig zu einer erlieblieben Störanfälligkeit.
Der erfindungsgemässe Rasensprenger ist gekennzeichnet durch eine scheibenförmige Sebleuderkapsel, in welche die Wasserzulei tung tangential mündet und in welche ein Austrittsstutzen axial hineinragt. Eine solche Anordnung kann frei von engen Düsen ge- lialten sein und verstopft sich daher praktisch nie. Sie bewirkt, dass (las in den Sprenger ein tretende Wasser zunächst in der Schleuder- kal)sel in rasen kreisende Bewegung gebracht wird, so dass ein Wirbel von hoher Wirbel- geschwindigkeit. entsteht.
Aus dieser rotie- i#enden Wasserscheibe nimmt dann der Aus trittsstutzen den sielt fortlaufend erneuernden Wirbelkern heraus und dieses Wasser strömt dann durch den Austrittsstutzen, um an sei nem äussern Rand in einen feinen Nebel zu zerreissen, der allseitig im Kreise versprüht wird. Es hat sich gezeigt, da.ss man auf diesem Wege nicht nur einen ziemlich grossen Aktions radius, sondern auch eine gleichmässige Be- sprengung des im Aktionsradius liegenden Feldes erhält.
Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegen standes veranschaulicht.
Fig. 1 zeigt einen Vertikalschnitt und Fig. 2 einen Horizontalschnitt durch einen Rasensprenger. Er besteht aus der scheiben förmigen Schleuderkapsel 1 mit dem tangen- tialen Schlauchanschluss 2 und dem zentralen. Austrittsstutzen 3, dessen Innenwand zweck mässig. in der dargestellten Weise etwas ab gerundet ist. Die Richtung der Wasserströ mung ist durch Pfeile angedeutet, der Aus trittskegel des versprühten Wassers durch den Winkelpfeil a. Die Einfachheit des be- s(#hriebenen Gerätes fällt ohne weiteres auf.
Lawn sprinkler. The invention relates to a lawn sprinkler which enables a large radius of action to be achieved without moving parts.
The lawn sprinklers, which were common in earlier years and simply consisted of a spray nozzle with a wide spray cone, only have a relatively small radius of action because the pressure drop in such a spray nozzle is so great that there is not much energy left to throw off the droplets. In order to obtain larger action radii, one has recently switched to letting the water jet emerge bundled from a nozzle with an impossible low pressure drop and to guide it in a circle through rotating deflection surfaces or the like.
In doing so, one gains a considerably larger radius of action; but the application of rotating parts leads. inevitably to an inherited susceptibility to failure.
The lawn sprinkler according to the invention is characterized by a disc-shaped Sebleuderkapsule into which the water supply line opens tangentially and into which an outlet nozzle protrudes axially. Such an arrangement can be free of narrow nozzles and therefore practically never becomes clogged. It has the effect that (read water entering the sprinkler first in the centrifugal caliper) is brought into lawn circular motion, so that a vortex of high vortex speed. arises.
From this rotating water disk the outlet nozzle takes out the continuously renewing vortex core and this water then flows through the outlet nozzle to tear into a fine mist on its outer edge, which is sprayed in circles on all sides. It has been shown that in this way one not only obtains a fairly large radius of action, but also a uniform sprinkling of the field within the radius of action.
On the accompanying drawing, an embodiment of the subject invention is illustrated.
1 shows a vertical section and FIG. 2 shows a horizontal section through a lawn sprinkler. It consists of the disc-shaped centrifugal capsule 1 with the tangential hose connection 2 and the central one. Outlet nozzle 3, the inner wall of which is expedient. is slightly rounded in the manner shown. The direction of the Wasserströ is indicated by arrows, the cone of the sprayed water from the angle arrow a. The simplicity of the used device is immediately noticeable.
