A method of utilizing pressurized fluid to produce rotary motion comprising the steps of: injecting said fluid into a motor housing; directing said fluid to a plurality of commutator ports; selectively transmitting said fluid through rotary valve means carrying N valve ports rotatable about a central axis to N sealed variable volume chambers formed between a gear like N toothed inner member with tooth root sections and intermediate tooth crown sections located between said tooth root sections mounted for rotation about said central axis and an annular outer member having a further axis circularly moveable about said central axis without rotation about said further axis, said outer member having an inner peripheral surface of N+1 generated arcuate teeth, said teeth\s profile having a continuously changing radius of curvature which provides for continuous cooperative contact with said toothed inner member to form said N sealed variable volume chambers and wherein such selective transmission of fluid occurs when the valve ports are aligned with the tooth root sections of the inner member; selectively expanding some of said sealed chambers by providing a pressure differential between said sealed chambers in order to produce a rotary motion with said inner member; withdrawing through said valve means said fluid from chambers that have reached their maximum expansion; and removing said fluid from said housing.
