DEFINITION

Classification: 416/79

(under the class definition) Apparatus wherein a working member* moves back and forth about an axis, or in an orbit, with an arc of movement of not more than 360 deg., the movement occurring as a proximate result of, or to directly effect, reaction between the member and the working fluid*.

(1) Note. Included under this definition is a working member which undergoes other movements (e.g., rotary) concurrently with the oscillatory reaction motion, the resultant working member motion generally being undulatory or wave-like.

(2) Note. The oscillatory movement for this definition must be that which is the immediate cause or effect of the fluid reaction and does not include mere adjustment (e.g., feathering) or support motion.
