ABSTRACT:
A friction clutch or brake includes at least one friction disk which is engageable by a piston to provide a braking effect of the disk. In order to cool the friction disk when the piston engages with the disk, a valve arrangement is arranged which injects oil onto the disk and through an opening provided in the disks. The actuation of the valve arrangement is provided in response to the piston, i.e. when the piston is moved towards the brake disks, the valve arrangement opens a channel through which the oil is injected toward the disks. In order to avoid a collection of oil in the vicinity of the disks after the braking action is terminated, the disks are provided with a toothed profile which discharges continuously oil to an external space and thus away from the friction disk. Thus no drag moments occur which are caused through oil adhering between the friction areas.
