Zusammenfassung
(DE) Bei einem fluidtechischen Gerät mit einem Gehäuse, das wenigstens eine Kolbenaufnahme (13) aufweist, in der wenigstens ein Kolben (14) axial verschieblich gelagert ist, wobei zwischen einer Umfangsseite (18) des Kolbens (14) und der der Umfangsseite (18) zugewandten Innenseite (19) der Kolbenaufnahme (13) fluiddicht abdichtende, den Kolben (14) umschließende Dichtmittel (20) angeordnet sind, ist der Kolben und/oder die dem Kolben (14) zugewandte Innenseite (19) der Kolbenaufnahme (13) zur Bildung der Dichtmittel (20) mit Fasermaterial versehen.
(EN) In a fluidic device, comprising a housing, which has at least one piston receiving element (13), in which the at least one piston (14) is supported in an axially displaceable manner, wherein sealing means (20) that enclose the piston (14) and provide a fluidic sealing effect are disposed between a circumferential side (18) of the piston (14) and the inside (19) of the piston receiving element (13) facing the circumferential side (18), the piston and/or the inside (19) of the piston receiving element (13) facing the piston (14) are provided with fibrous material in order to produce the sealing means (20).
(FR) L'invention concerne un appareil fluidique avec un corps qui possède au moins un logement de piston (13) dans lequel est monté au moins un piston (14) pouvant se déplacer axialement. Entre une face périphérique (18) du piston (14) et la face intérieure (19) du logement de piston (13) tournée vers la face périphérique (18) sont disposés des moyens d'étanchéité (20) entourant le piston (14) et assurant une étanchéité au fluide. Le piston (14) et/ou la face intérieure (19) du logement de piston (13) tournée vers le piston (14) est doté de matériau fibreux pour former les moyens d'étanchéité (20).
