摘要： A length-adjustable piston cylinder unit comprises a casing which is filled with a fluid and has a central longitudinal axis; a guide and sealing unit which seals off the casing at a first end; a piston rod which is guided through the guide and sealing unit out of the first end of the casing in a sealed manner; a piston which is connected with the piston rod and is guided in the casing in a sealed manner; a first interior portion which is bounded between the piston and the guide and sealing unit; a second interior portion which is bounded by the piston and faces away from the first interior portion; an adjustment valve arranged in the piston for optionally connecting the two interior portions to each other; a guide sleeve which is arranged for displacement on the casing and is concentric to the central longitudinal axis, the guide sleeve being secured to the piston rod at a sleeve end and comprising at least one latch opening which is spaced from the sleeve end along the central longitudinal axis; and a latch sleeve arranged on the guide sleeve, the latch sleeve comprising at least one latch protrusion for engagement into the at least one latch opening, with the at least one latch protrusion of the latch sleeve being arrangeable in the at least one latch opening of the guide sleeve for arranging the piston cylinder unit in a secured position so that the displaceability of the guide sleeve connected with the piston rod relative to the casing is blocked.
摘要翻译：长度可调的活塞缸单元包括一个填充有流体并具有中心纵向轴线的壳体; 引导和密封单元，其在第一端处密封壳体; 活塞杆，其以密封方式被引导通过所述引导和密封单元从所述壳体的所述第一端出来; 活塞，其与活塞杆连接并以密封的方式在壳体中被引导; 第一内部部分，其限定在活塞和引导和密封单元之间; 第二内部部分，其由所述活塞限定并且远离所述第一内部部分; 调节阀，布置在活塞中，用于可选地将两个内部部分彼此连接; 引导套筒，其布置成在壳体上移位并且与中心纵向轴线同心，导向套筒在套筒端处固定到活塞杆，并且包括至少一个闩锁开口，其沿着中心与套筒端部间隔开纵轴; 以及布置在所述引导套筒上的闩锁套筒，所述闩锁套筒包括用于接合到所述至少一个闩锁开口中的至少一个闩锁突起，所述闩锁套筒的所述至少一个闩锁突起可布置在所述至少一个闩锁开口中的至少一个闩锁开口中用于将活塞缸单元布置在紧固位置的引导套筒，使得与活塞杆相连的引导套筒相对于壳体的位移能力被阻挡。
