Gas- und Luftgebläse. Patentiert im Deutschen Reiche vom 7. März 1908 ab.Gas and air blower. Patented in the German Empire on March 7, 1908.

Die vorliegende Erfindung betrifft eine Einrichtung an Gas- und Luftgebläsen, bestehend aus einem Arbeitszylinder mit exzentrisch in einem Gehäuse umlaufenden Kolben, deren Fliehkraft durch einen oder mehrere an Vorsprüngen an ihnen angreifende jstarre, mit den Kolben umlaufende Ringe aufgenommen wird.The present invention relates to a device consisting of gas and air blowers from a working cylinder with eccentrically rotating pistons in a housing, whose Centrifugal force due to one or more jars acting on projections on them, with rings surrounding the piston are added.

Bei den bisherigen Konstruktionen sind dieIn the previous designs, the

ίο Tragringe in dem Gehäuse gelagert und mit Dichtungen versehen, die sich gegen die Innenfläche des Arbeitszylinders legen. Ab-1 gesehen von der beträchtlichen Reibung, die sich durch das Gleiten der Ringe an der Zylinderwandurig bei dem verhältnismäßig großen Halbmesser ergibt, ist es aber auch unmöglich, bei allen Geschwindigkeiten den Druck, welchen die in den Kolben angeordnete Dichtungsleisten gegen die Zylinderwandung ausüben, aufzuheben. Dieses hat bei den bekannten, hier in Frage kommenden Anordnungen, da die Dichtungsleisten der Kolben sich nicht über die ganze Länge des Zylinders erstrecken, eine ungleichmäßige Abnutzung des Zylinders zur Folge.ίο Support rings stored in the housing and provided with seals that lie against the inner surface of the working cylinder. Seen ex 1 of the considerable friction that results to the cylinder wall Obergurig at the relatively large radius by the sliding of the rings, but it is also impossible at all speeds the pressure which the exercise in the piston arranged sealing strips against the cylinder, to cancel. In the case of the known arrangements in question here, since the sealing strips of the pistons do not extend over the entire length of the cylinder, this results in uneven wear of the cylinder.

Die geschilderten Nachteile werden bei der vorliegenden Erfindung dadurch vermieden, daß die Tragflächen der Ringe an eine Stelle verlegt sind, wo die durch die Reibung hervorgerufenen Abnutzungen unschädlich sind, weil hier keine dichtenden Flächen vorhanden sind. Gleichzeitig ergibt sich hierbei der Vorteil, daß der Halbmesser, an welchem der Reibungswiderstand wirkt, wesentlich verkleinert wird, und daß, da die an den Kolben angeordneten Dichtungsstreifen sich über die ganze Länge des Zylinders erstrecken, eine gleichmäßige Abnutzung bewirkt wird.The disadvantages outlined are avoided in the present invention by that the bearing surfaces of the rings are relocated to a point where the friction caused by the friction Wear and tear are harmless because there are no sealing surfaces here. At the same time there is the advantage that the radius at which the frictional resistance acts is significantly reduced is, and that, since the sealing strips arranged on the pistons extend over the extend the entire length of the cylinder, a uniform wear is caused.

Auf der Zeichnung ist das Gebläse in einer Vorderansicht mit abgenommenem Zylinderdeckel dargestellt.The drawing shows the fan in a front view with the cylinder cover removed shown.

Der exzentrisch gelagerte Arbeitszylinder B dreht sich innerhalb des Gebläsegehäuses D und trägt in radialen Schlitzen Kolben C. Diese legen sich mit Zapfen oder Rollen H gegen die Innenseite jiines oder mehrerer Ringe A' an, welche die Fliehkraft der umlaufenden' Kolben aufnehmen und einen Pressungsdruck von dem Gehäuse D fernhalten.. Gegebenenfalls werden die Rollen g. noch von Ringen A geführt, die sich mit ihrer Außenseite gegen sie anlegen.The eccentrically mounted working cylinder B rotates within the fan housing D and supports in radial slots piston C. These lie with pins or rollers H against the inside jiines or more of rings A 'at which the centrifugal force of the orbiting' record piston and a compression pressure of keep away from the housing D. If necessary, the rollers g. still led by rings A , the outside of which lay against them.

Zur Aufnahme der aus den Fliehkräften sich ergebenden, an den Ringen A1 bzw. A einseitig wirkenden Kraft dient eine_ Stütze K 55?- für den Ring" A oder eine solche L für den Ring A1. "' A support K 55? - for the ring " A or such an L for the ring A 1 " is used to absorb the force resulting from the centrifugal forces and acting on one side on the rings A 1 or A.
