Abstract

Die Exzenterpumpe weist eine in einem Pumpengehäuse (8) drehbar gelagerte Exzenterwelle (3) auf. Sie treibt wenigstens eine in einem Exzenterraum (7) angeordnete Förderscheibe (6) an, welche Fluid in einer Förderkammer (16) zwischen der Außenseite der Förderscheibe (6) und der Innenseite eines Außenringes (17) von einem Einlassanschluss zu einem Auslassanschluss fördert. Die Förderkammer (16) ist seitlich von einer in einem Ausgleichsraum (20) im Pumpengehäuse (8) angeordneten, elastischen Dichtscheibe (21) begrenzt, die in die Dichtstellung kraftbeaufschlagt ist. Aufgrund ihrer Elastizität kann sich die Dichtscheibe (21) bei einem entsprechend großen Druck des Fluid in der Förderkammer (16) elastisch verformen. Die Fördervorrichtung hat die Exzenterpumpe (1), die mit wenigstens einer Luftpumpe antriebsverbunden ist.
