Abstract
The present invention relates to a piston-cylinder arrangement (2) for the operating device of a clutch, having a cylinder (16), a piston (36) which is arranged in the cylinder (16) and can be displaced in the axial direction (4, 6), and at least one locking element (50) which is associated with the piston (36), wherein the piston (36) can be displaced from a first position into a second position in which the locking element (50) can be moved from a released position into a locked position in which the piston (36) is locked in the second position via the locking element (50) in a positively locking manner. According to the invention, the piston (36) can be displaced by means of a locking piston (52), which in the released position of the locking element (50) is connected via the locking element (50) to the piston (36) in a positively locking manner in the axial direction (4, 6) and in the second position of the piston (36), with displacement of the locking element (50) from the released position into the locked position relative to the piston (36), can be displaced in the axial direction (4) from an initial position into a locked position.
