Abstract:
(DE) Bekannte Vorrichtungen haben einen exzentrisch in einer Pumpenkammer gelagerten Rotor (15) und am Umfang des Rotors angeordnete Nuten (40), in denen an einer Formlaufbahn (24) der Pumpenkammer anliegende Rollen als Dichtkörper vorgesehen sind. Zwischen dem Rotor (15) und der Formlaufbahn (24) ist ein m Spalt (48) gebildet, der von den Rollen in Spalträume (49) aufgeteilt ist, die mittels der Rollen gegeneinander abgedichtet sind. Erfindungsgemäß ist vorgesehen, dass die Dichtk&dgr;rper (39) als elastische Federelemente ausgebildet sind.
(EN) Generic devices comprise a rotor (15), eccentrically mounted in a pump chamber, and grooves (40), disposed on the periphery of a rotor and receiving rolls as the sealing bodies, said sealing bodies resting against a curved track (24) of the pump chamber. A gap (48) is defined between the rotor (15) and the curved track (24) and is subdivided into gap spaces (49) that are sealed from each other by the rolls. The invention is characterized in that the sealing bodies (39) are configured as elastic spring elements.
(FR) Les dispositifs connus ont un rotor (15) qui est monté excentrique dans une chambre de pompe et présente, sur sa circonférence, des rainures (40) dans lesquelles se trouvent, en tant que corps d'étanchéité, des rouleaux qui sont en contact avec un chemin de roulement de forme (24) de la chambre de pompe. Une fente (48), formée entre le rotor (15) et le chemin de roulement de forme (24), est divisée par les rouleaux en intervalles (49) qui sont étanchéifiés les uns par rapport aux autres par des rouleaux. Selon l'invention, les corps d'étanchéité (39) se présentent sous la forme d'éléments élastiques.
