ABSTRACT:
A combined clutch and double-action braking device for use in intermittently operating machines having a rotational driving shaft and a separate driven shaft, clutch or coupling disks secured to the driving shaft, and two braking disks fixedly arranged on a stationary holder, the device comprising a supporting disk secured to the driven shaft and defining a peripheral part and an intermediate part, the peripheral part projecting between the two braking disks, the intermediate part being extended to form two opposite tubular spaces divided by a fixed partition and each having an axially movable wall portion forming a pressure disk sealingly closing the assigned space; in rest condition, pressure springs resiliently urge each pressure disk against an assigned braking disk, whereas in actuated position pressure fluid is applied into the spaces to disengage the pressure disks from the braking disks and for urging one of the pressure disks against the coupling disk.
