Abstract

Es wird eine Zylinderanordnung vorgeschlagen, mit einem Zylinder (10), welcher ein Zylindergehäuse (12) und eine Kolbenstange (18) aufweist, und einer Distanzscheibenanordnung (30), welche einen Träger (32) und eine Vielzahl von mit dem Träger (32) verbundene bewegliche Distanzscheiben (34) umfasst. Die Distanzscheiben (34) sind in eine Aufbewahrstellung (34a) und in eine Anschlagstellung (34b) schwenkbar, wobei die Distanzscheiben (34) in der Anschlagstellung (34b) einen mechanischen Anschlag bilden und das Einfahren der Kolbenstange (18) relativ zum Zylindergehäuse (12) begrenzen. Die Anschlagposition ist dabei von der Anzahl der in Anschlagstellung gebrachten Distanzscheiben (34) abhängig. Die Zylinderanordnung ist dadurch gekennzeichnet, dass die Distanzscheibenanordnung (30) angrenzend zur Kolbenstange (18) mit dem Zylinder (10) verbunden ist, die Distanzscheiben (34) eine an die Kolbenstange (18) angepasste Form aufweisen und in der Anschlagstellung (34b) die Kolbenstange umgebend angeordnet sind, wobei der Anschlag zwischen dem Zylindergehäuse (12) und der Kolbenstange (18) ausgebildet wird.

Figure imgaf001
A cylinder arrangement is proposed, comprising a cylinder (10) which has a cylinder housing (12) and a piston rod (18), and a spacer assembly (30) which has a support (32) and a plurality of supports (32). connected movable spacers (34). The spacers (34) are pivotable into a storage position (34a) and into a stop position (34b), wherein the spacers (34) in the stop position (34b) form a mechanical stop and retraction of the piston rod (18) relative to the cylinder housing (12 ) limit. The stop position is dependent on the number of placed in the stop position spacers (34). The cylinder arrangement is characterized in that the spacer arrangement (30) is connected to the cylinder (10) adjacent to the piston rod (18), the spacers (34) have a shape adapted to the piston rod (18) and in the stop position (34b) Surrounding the piston rod are arranged, wherein the stop between the cylinder housing (12) and the piston rod (18) is formed.
