A clutch device within whose housing a first fluid chamber and a second fluid chamber are separated by a piston which is movable by a fluid pressure differential between the fluid chambers. The piston serves to actuate a friction clutch whose friction surfaces are arranged in the first fluid chamber. Fluid can be guided through the first fluid chamber independent from the fluid pressure in the second fluid chamber in order to conduct frictional heat away from the friction clutch and its friction surfaces. For this purpose, fluid passages through which fluid allocated to the first fluid chamber can flow are allocated to the friction surfaces. It is proposed that there is a minimum fluid quantity which flows through the fluid passages and the quantity of fluid flowing through the first fluid chamber is adjustable by means of this minimum fluid quantity, for which purpose the minimum fluid quantity is in a fixed relationship with the amount of fluid introduced into the first fluid chamber and removed from the first fluid chamber.
