The invention relates to a hydraulic device (1) having a cylinder (3) and a piston (2) guided in the cylinder (3), which piston (2) can be displaced between a working position and an end position, the piston (2) in the working position sealingly dividing the cylinder chamber into a first subspace (5) and a second subspace (6), and the piston (2) in the end position of the piston (3) in which the piston (2) is arranged in the first subspace (5) and the second subspace (6). The first subspace (5) and the second subspace (6) are fluidically connected to each other via an overflow channel (13). According to the invention, a flow path (14) is formed in the piston (2), said flow path (14) extending between the end side of the piston (2) and the outer circumferential side of the piston (2), and in the end position of the piston, the overflow channel (13) is at least partially formed by the flow path (14).

    本发明涉及一种液压装置(1),其具有缸(3)和在所述缸(3)中引导的活塞(2),所述活塞(2)能够在工作位置和末端位置之间移动,其中,所述活塞(2)在工作位置将缸室密封地分为第一子空间(5)和第二子空间(6),并且在所述活塞(3)的末端位置,所述第一子空间(5)和所述第二子空间(6)通过溢流通道(13)流体传导地相互连接。在所述活塞(2)中构成流路(14),所述流路(14)在所述活塞(2)的端侧和所述活塞(2)的外周侧之间延伸,并且在所述活塞的末端位置,所述溢流通道(13)至少部分地由所述流路(14)构成。
