Hydraulically operated double clutch with first and second piston-cylinder devices for engagement and disengagement of the respective clutch unit. The cylinder chamber (17) of the first piston-cylinder device is delimited between its piston (18) and a first wall (4) of the clutch housing (1), while the cylinder chamber (24) of the second piston-cylinder device is delimited between its piston (25) and the first mentioned piston (18). A third cylinder chamber (30) is delimited between the piston (25) of the second piston-cylinder device and a second wall (6) of the clutch housing (1). Channels (31-34) are arranged for supply of pressure medium to and from the cylinder chambers, so that the pressure of the pressure medium in the engagement direction on either piston generates at the same time a return force on the other piston, balancing the force in the engagement direction generated by the centrifugal force on the pressure medium.
