DEFINITION

Classification: 417/375

(under subclass 321) Apparatus in which the motor is of the type which includes a movable working member (e.g., piston, turbine runner, diaphragm, etc.) which is motivated by a fluid.

SEE OR SEARCH THIS CLASS, SUBCLASS:

329, for motors of the type which are motivated by the simple force of weight of a fluent material.

364, for fluid motors of the type which are motivated by the burning of a combustible mixture within an expansible chamber

of the motor (i.e., internal combustion engine).
