Abstract

Es wird ein kolbenstangenloser Druckmittelzylinder (10) vorgeschlagen, bei dem das den Innenraum (13) abdichtende, innere Dichtband (17) durch eine formschlüssig arbeitende Halteeinrichtung (19) so im Längsschlitz (15) gehalten wird, daß neben einer stabilen Halterung des Dichtbandes (17) eine sichere Abdichtung auch bei drucklosem Druckmittelzylinder (10) gegeben ist. Paarweise am Dichtband (17) auskragende Halterippen (32) ragen in gehäuseseitige Haltenuten (23) im Längsschlitz (15), wodurch paarweise angeordnete Dichtlippen (37) dichtend an der Zylinderinnenwand (31) gehalten werden, während die beiden Auflageflächen (34) des Dichtbandes (17) noch im Abstand von gegenüberliegenden Stützflächen (27) im Zylinderrohr (11) liegen und erst bei druckbeaufschlagtem Druckmittelzylinder (10) zur Anlage kommen.

Figure 00000001
A rodless pressure medium cylinder (10) is proposed, in which the inner sealing band (17) sealing the interior (13) is held in the longitudinal slot (15) by a form-fitting holding device (19) such that in addition to a stable mounting of the sealing band ( 17) there is a secure seal even when the pressure medium cylinder (10) is depressurized. Retaining ribs (32) projecting in pairs on the sealing tape (17) protrude into housing-side retaining grooves (23) in the longitudinal slot (15), as a result of which sealing lips (37) arranged in pairs are held in a sealing manner on the cylinder inner wall (31), while the two contact surfaces (34) of the sealing tape (17) are still at a distance from opposite support surfaces (27) in the cylinder tube (11) and only come into contact when the pressure medium cylinder (10) is pressurized.
