Abstract

Die Erfindung betrifft eine Verdrängungspumpe (18, 65) mit einem Flügel zum gegenseitigen Trennen der beiden Kammern im Gehäuseraum (12, 62), der von einer im Pumpengehäuse (10, 61) gelagerten Antriebswelle (14, 63) antreibbar und zu dieser in einer deren Achse enthaltenden Ebene radial verschiebbar geführt ist und der endseitig jeweils eine mit der Innenumfangswand des Gehäuseraumes (12, 62) abdichtend zusammenwirkende Abdichtleiste (20 bzw. 22; 66) trägt, die zur Achse der Antriebswelle (14, 63) voneinander unabhängig radial beweglich sind, wobei am Flügel (18, 65) wenigstens ein Kraftspeicher (48 bzw. 67) vorgesehen ist, der versucht, beide Abdichtleisten (20, 22; 66) ständig mit der Innenumfangswand des Gehäuseraumes (12, 62) abdichtend in Berührung zu halten.

Figure 00000001
The invention relates to a displacement pump (18, 65) with a wing for mutually separating the two chambers in the housing space (12, 62), which can be driven by a drive shaft (14, 63) mounted in the pump housing (10, 61) and to this in one whose axis-containing plane is guided radially displaceably and which carries at the end in each case a sealing strip (20 or 22; 66) which cooperates with the inner circumferential wall of the housing space (12, 62) and which is independently radially movable relative to the axis of the drive shaft (14, 63) at least one energy accumulator (48 or 67) is provided on the wing (18, 65), which tries to keep both sealing strips (20, 22; 66) sealingly in contact with the inner peripheral wall of the housing space (12, 62) ,
