Abstract (en)

[origin: EP1106841A2] The drive has a double-action cylinder-piston unit with a pressure chamber formed by a cylinder casing, an annular piston, a rotatable threaded spindle in a bearing and a spindle rotation blocking element. The spindle bearing is mounted in an end housing. The piston internal thread is engaged by the spindle. A blocking piston subject to a pressurized medium in an end housing bore has a protrusion for engaging the spindle or a blocking sleeve. The drive has a double-action cylinder-piston unit with a pressure chamber formed by a cylinder casing and an annular piston (19), whose piston rod fits concentrically into a rotatably mounted threaded spindle (28) in a bearing (36) and engages its thread, and a spindle rotation blocking element. The spindle bearing is mounted in an end housing (9) and the piston has an internal thread engaged by the spindle. A blocking piston (37) subject to a pressurized medium is arranged in a bore in the end housing and has a blocking protrusion (38) for engagement with the spindle or a connected blocking sleeve (33).
