Abstract
A piston-cylinder with a work cylinder filled with a fluid, a hollow piston rod displaceably arranged in the work cylinder along a longitudinal axis, a connection element at an end located outside the work cylinder and in the work cylinder, a piston that divides the work cylinder into first and second work spaces. A valve needle in the piston rod has a channel extending in axial direction arranged in the piston rod. The valve needle has a recess at one end. The valve needle is rotatable such that a flow of fluid is controllable. A lever extends in radial direction and is swivelably acted upon by an adjusting unit at the end of the valve needle outside the work cylinder. The adjusting unit is arranged at the connection element entirely outside the flow of force of the piston-cylinder unit.
