KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es ist bekannt, der durch die Mündung des Saugmundstückes von Staubabsaugevorrichtungen eintretenden Saugluft bestimmbare Mengen von Nebenluft zwecks Abschwächung der Saugwirkung durch Öffnungen im Saugrohr zutreten zu lassen.It is known that through the mouth of the suction mouthpiece of dust extraction devices incoming suction air, determinable amounts of secondary air for the purpose of weakening the suction effect through openings in the suction pipe to be allowed to enter.

Beim Gegenstand vorliegender Erfindung ist zu dem Zwecke die die Nebenluft in das Saugrohr einlassende Öffnung durch ein Gehäuse überdeckt, welches aus einer feststehenden Kapsel und einer bewegbaren Schraubenmutter besteht; die einen gegen den Kapselrand anpreßbaren, nachschleif baren Kegel trägt, so daß durch Verschiebung des Kegels die Größe der Eintrittsöffnung für die Nebenluft zwischen Kegel und Kapselrand verändert werden kann, wodurch die Saugwirkung an der Mündung des Mundstückes verändert wird.In the subject matter of the present invention, the secondary air in the Suction pipe inlet opening covered by a housing, which consists of a stationary Capsule and a movable nut; one against the edge of the capsule compressible, regrind ble cone carries, so that by shifting the cone the size of the inlet opening for the secondary air between the cone and the edge of the capsule changed can be, whereby the suction at the mouth of the mouthpiece is changed.

In der Zeichnung ist der Gegenstand der Erfindung in einer beispielsweisen Ausführungsform dargestellt und zeigt:
Fig. ι eine Ansicht desselben,
Fig. 2 in größerem Maßstabe einen Schnitt nach A-B der Fig. 1.
In the drawing, the object of the invention is shown in an exemplary embodiment and shows:
Fig. Ι a view of the same,
FIG. 2 shows, on a larger scale, a section according to AB in FIG. 1.

α ist das Mundstück, welches mit seinem Ende b an eine nicht gezeichnete Saugleitung einer Staubabsaugevorrichtung angeschlossen wird; c bedeutet eine oder mehrere Öffnungen im Mundstück. Diese Öffnungen c sind durch ein Gehäuse überdeckt, welches aus einer am Mundstück festsitzenden Kapsel d und einer auf einem ebenfalls festen Gewindeteil f des Mundstückes sitzenden bewegbaren Mutter g α is the mouthpiece, which is connected with its end b to a suction line (not shown) of a dust extraction device; c means one or more openings in the mouthpiece. These openings c are covered by a housing, which consists of a capsule d fixed on the mouthpiece and a movable nut g seated on a likewise fixed threaded part f of the mouthpiece

besteht* welche einen Kegel h besitzt, der in die Kapsel d eindringt und gegen den Kapselrand i anpreßbar ist.consists * which has a cone h which penetrates the capsule d and can be pressed against the capsule rim i.

Ist der Kegel h gegen den Kapselrand i angepreßt, so kann nur Luft durch die Mündung k des Mundstückes eindringen. Wird aber die Mutter g von der Kapsel d weggedreht, also das Gehäuse geöffnet, so kann Nebenluft zwischen dem Konus h und dem Kapselrande i sowie durch die Öffnungen im Mundstück zum Hauptluftstrom hinzutreten. Die Anordnung des Kegels gestattet eine stetige und nicht stoßweise Regelung der durch das so gebildete Ventil eintretenden Nebenluft und damit auch der Saugwirkung, außerdem aber auch einen festen, luftdicht bleibenden Abschluß des Gehäuses nach außen und ermöglicht ein Nachschleifen des durch i und h gebildeten Ventiles. Je nach dem Abstande des Kegels von dem Kapselrande ändert sich die Menge der zutretenden Nebenluft. If the cone h is pressed against the capsule rim i , only air can penetrate through the mouth k of the mouthpiece. If, however, the nut g is turned away from the capsule d, i.e. the housing is opened, secondary air can enter the main air flow between the cone h and the edge of the capsule i and through the openings in the mouthpiece. The arrangement of the cone allows a steady and non-intermittent control of the secondary air entering through the valve formed in this way and thus also the suction effect, but also a firm, airtight closure of the housing to the outside and enables regrinding of the valve formed by i and h. Depending on the distance between the cone and the edge of the capsule, the amount of secondary air entering changes.

Auf dem aus der Kapsel vorstehenden Teile des Kegels kann eine Teilung angebracht sein.A division can be applied to the part of the cone protruding from the capsule.
