A rotary apparatus adapted to perform as, compressor, pump, motor or an internal combustion engine; said apparatus comprising of two vanes, two holl ow cylindrical sleeves, hollow cylindrical liner, cams and associated linkages, couplings, shaft, clutch and braking/locking arrangement; said vanes are fitted on to the curved surface of the sleeves, one vane on each sleeve, suc h that the vanes are radial to sleeve's curved surface and at one of the ends of each sleeve so that the vane's surface protrudes out of the sleeve's end; sa id sleeves placed such that their ends, fitted with vanes are placed adjacent, with the vanes angularly displaced; said vanes are placed inside a liner; sa id liner's inner surface is contoured along the path traced by vane edge while rotating about the said axis; said inner surface allows rotation of the vane s about the said axis; said vanes divide the said enclosure formed inside the liner into two sealed chambers; enclosure; said two sleeves, are coupled and uncoupled with a shaft by means of coupling arrangement actuated by cams or other timing devices; said cams or timing devices are dependent on sleeve position; said cams or timing devices actuate said braking/locking arrangements such that each vane is held at a predetermined position alternately, and the vanes are free to rotate through an defined angle alternately; said cams or timing devices allow both vanes to rotate simultaneously through an predefined angle; said cams or timing devices defines the angle by which the vanes are separated, rotated simultaneously o r independently.
