Abstract

Eine Vorrichtung zur Umwandlung einer Drehbewegung in eine hin- und hergehende Bewegung weist ein angetriebenes Nockenelement (2) und ein vom Nockenelement (2) verschieb- oder verschwenkbares Nockenfolgeelement (10) auf, wobei das Nockenelement (2) drehbar in einem flexiblen Umschließungselement (4) angeordnet ist, das in einer zur Drehachse (8) des Nockenelementes (4) senkrechten Ebene beweglich und mit dem Nockenfolgeelement (10) verbunden ist. In der Umfangsfläche (94) des Nockenelementes (2) und/oder der Innenfläche (95) des flexiblen Umschließungselementes (4) ist zumindest eine Mündungsöffnung (98, 99) für ein reibungsverminderndes Medium vorgesehen. Das Nockenelement (2) und/oder das Umschließungselement (4) weist Flächen (96, 97) auf, die zur Umfangsfläche (94) des Nockenelementes (2) in Umfangsrichtung geneigt und nacheinander angeordnet sind.
