<p>A fluid actuated clutch is mounted on a rotating driving shaft of a prime mover, to selectively transmit rotation to a driven shaft. The clutch comprises a rotary structure of substantially annular shape rigidly mounted on the driving shaft, a stationary structure of substantially annular shape supported by a pillow block of the clutch and located independently of the rotary structure while leaving a space therebetween. A fluid actuated sealing piston having a fluid passage and mounted in the stationary structure selectively effects a seal between the rotary and stationary structures, and supplies and discharges fluid under pressure into and from, respectively, an inflatable friction member. Once the seal is effected, the fluid is directed within the rotary structure through the fluid supplying means to activate the friction device and transmit rotative motion to the driven body. A normally closed check valve in the clutch may be opened by remote control means to release fluid pressure from the clutch. A pressure sensing device controls fluid supply to the clutch after pressure therein has reached a predetermined level.</p> |
