Pivoting device for pivoting of the compositions, in particular for use in the car body construction of the automotive industry, in opposite directions with a compressed air to alternately on both sides by a piston-cylinder unit, whose in a cylinder (3) so as to be longitudinally displaceable guided oscillating piston (4) is sealed by means of a piston rod (6) and by way of a toggle joint system (15) is a pivoting part (48) by, for example, 135° back and forth (a-b), wherein the drives with the toggle joint system (15) is connected by a piston rod (6) in the direction of the rotary piston (4) which opens chamber (26), in which a on the cylinder cover (12) of the cylinder (3) of the piston-cylinder unit which is arranged a fixed position rod (30) extends, the sealed at its end a calming piston (31) of the sealed in the chamber (26) so as to be longitudinally displaceable and is guided sealingly, wherein this calming piston (31) and the connecting rod part (30) axially by a longitudinal channel (33) are penetrated in the area of the base cover (12) designed as a cylinder cover (12) via a channel (35) to a solenoid operated shut-off valve (36) to a compensating chamber (45) is connected, while on the opposite side of the calming piston (31), the chamber (26) via a transverse and longitudinal channel (34), likewise in the region of the platform (12) via a solenoid operated valve (38) at the same compensating chamber (45) is connected, in which the piston rod (6), the connecting rod part (30) and the compensating chamber (45) are arranged coaxially with respect to one another, and that in the chamber (26) and in the longitudinal channels (33, 34) as well as in the compensating chamber (45) is arranged a hydraulic medium.
