Title (DE) KOLBENZYLINDER-AGGREGAT
(EN) PISTON-CYLINDER UNIT
(FR) ENSEMBLE VÉRIN HYDRAULIQUE
Abstract:
(DE) Kolbenzylinder-Aggregat (1), umfassend eine Kolbenstange (5), an der mindestens ein Kolben (9) angeordnet ist, der an einer äußeren Mantelfläche (37) einen radial elastischen Kolbenring (33) aufweist, der in Abhängigkeit der Hublage der Kolbenstange (5) in einen Zylinder (11) eintaucht und dabei einen kleinere Durchmesser D2 aufweist als in einer Hublage, bei der sich der Kolben (9) außerhalb des Zylinders (3) befindet, wobei der Kolbenring (33) einen Anschlag (47) aufweist, der einen maximalen Durchmesser des Kolbenrings (33) bestimmt.
(EN) Disclosed is a piston-cylinder unit (1) comprising a piston rod (5) on which at least one piston (9) is arranged that has a radially elastic piston ring (33) on an outer lateral surface (37); depending on the stroke position of the piston rod (5), the piston ring (33) plunges into a cylinder (11) and has a smaller diameter (D2) therein than in a stroke position in which the piston (9) is outside the cylinder (3); the piston ring (33) includes a stop (47) which determines a maximum diameter of the piston ring (33).
(FR) L'invention concerne un ensemble vérin hydraulique (1) comprenant une tige de piston (5) sur laquelle est disposé au moins un piston (9) qui comprend, sur une surface extérieure (37), un segment de piston (33) radialement élastique, qui s'introduit dans un cylindre (11) en fonction de la position de la course de la tige de piston (5) et présente ainsi un diamètre inférieur (D2) à celui dans une position de course dans laquelle le piston (9) se situe en dehors du cylindre (3), ledit segment de piston (33) présentant une butée (47) qui détermine un diamètre maximal dudit segment de piston (33).
