Description

Drehkolbenpumpe oder -gebläse Die Erfindung betrifft eine Drehkolbenmaschine, welche als Pumpe oder Gebläse arbeitet. Der im Gehäuse abrollende Kolben kann, wie bekannt, durch Federn, andere elastische Mittel oder Gegenexzenter zur besseren Abdichtung im Gehäuse gebracht werden. Die Saugseite wird von der Druckseite durch die Widerlagerklappe, die auf dem Kolben aufliegt, getrennt. Außer dieser bekannten Widerlagerklappe befindet sich ebenfalls im Gehäuse gelagert eine die Neuerung ausmachende zweite Klappe, welche lose auf der Widerlagerklappe aufliegt und so die Pumpe von der Druckleitung bei sehr geringem schädlichen Raum abschließt (Rückschlagklappe). Die Pumpe oder das Gebläse wird durch diese Anordnung sehr einfach im Bau, klein und billig. Bei Anordnung zweier Kolben nebeneinander, die natürlich durch eine Scheibe getrennt sein müssen, erreicht man Gleichmäßigkeit der Förderung.Rotary piston pump or blower The invention relates to a rotary piston machine, which works as a pump or fan. The piston rolling in the housing can, as known by springs, other elastic means or counter eccentric for better Sealing are brought into the housing. The suction side is through from the pressure side the abutment flap, which rests on the piston, separated. Except for this well-known one The abutment flap is also located in the housing, which is a major innovation second flap, which rests loosely on the abutment flap and thus the pump of the pressure line closes off with very little harmful space (non-return valve). This arrangement makes the pump or the fan very simple in construction, small and cheap. When arranging two pistons side by side, which of course by a Disk must be separated, one achieves uniformity of the conveyance.

Die Pumpe gemäß Abb. i und 2 besteht aus einem oder mehreren Gehäusen i; diese sind durch Scheiben 2 getrennt.- In den Stirnwänden 3 ist die Exzenterwelle 4. gelagert. Die Exzenter können Schlitze 5, welche mit einer elastischen Masse ausgefüllt sind, oder Blattfedern 6 erhalten. Außerdem kann bei jedem Exzenter eine Feder 6' angeordnet werden. Das auf dem Exzenter lose sitzende Kugellager 7 (kann auch -wegfallen) trägt den Ring 8, der als Kolben wirkt. Dieser wird in dem Gehäuse in entgegengesetzter Drehrichtung der Exzenterwelle abgerollt. Zur besseren Abdichtung an den Stirnseiten ist ein Ring 9 in dem Kolben vorgesehen, welcher durch kleine Druckfedern io an die Stirnseiten angedrückt wird. Dieser Ring 9 kann auch fehlen und die Abdichtung an den Stirnseiten und auch am Umfang an der innerer. Gehäusewandung durch Leder- oder Gummieinlagen im Kolben 8 erfolgen. Im Gehäuse sind die Klappen ii und 12 gelagert.The pump according to Fig. I and 2 consists of one or more housings i; these are separated by disks 2. The eccentric shaft 4 is mounted in the end walls 3. The eccentrics can have slots 5, which are filled with an elastic mass, or leaf springs 6. In addition, a spring 6 'can be arranged on each eccentric. The ball bearing 7 , which sits loosely on the eccentric (can also be omitted), carries the ring 8, which acts as a piston. This is unrolled in the housing in the opposite direction of rotation of the eccentric shaft. For better sealing at the end faces, a ring 9 is provided in the piston, which is pressed against the end faces by small compression springs. This ring 9 can also be missing and the seal on the end faces and also on the circumference of the inner one. The housing wall is made by leather or rubber inserts in the piston 8. The flaps ii and 12 are mounted in the housing.

Die erstere, die, wie bekannt, als W'iderlager wirkt, liegt lose auf dem Kolben 8 auf und trennt die Saug- von der Druckseite. Die neue Klappe 12 (Rückschlagklappe) liegt auf der Klappe i i auf und schließt den Pumpenraum von der Druckleitung ab. Durch Schrauben 13 werden die Gehäuseteile und Flanschen zusammengehalten.The former, which, as is known, acts as an abutment, rests loosely on the piston 8 and separates the suction from the pressure side. The new flap 12 (non-return flap) rests on the flap ii and closes the pump chamber from the pressure line. The housing parts and flanges are held together by screws 13.
