A compact, rotary gas-operated motor having only three moving components including valving. Pressurized gas entering through a crank causes it to move within a slot in an elongate rotor which rotates end-over-end within a generally triangular chamber. Pressurized gas bypassed to the space between the rotor and a chamber wall also causes rotation. Expansion ratios of 5:1 to 15:1 or more may readily be obtained.
