James Watt who invented thesteam engine’s connecting rod crank mechanism which made it possible to convertthe piston’s reciprocating motion into rotary motion designed an oscillatingpiston machine in which a wing-shaped rotary blade performed an almost completerevolution uncovering inlet ports in a chamber separated off by a curved radialwall
