DEFINITION

Classification: 60/508

(under the class definition) Apparatus comprising a motor having a working chamber and a working member therein with means affecting the temperature and thus the pressure of fluid after being supplied to and isolated within the working chamber to actuate the working member.

(1) Note. The motor working chamber and member includes a cylinder and piston or its equivalent.

(2) Note. See Class 92, Schedule, section II for a definition of a working chamber and member for an expansible chamber type motor.

(3) Note. See Class 415 for a definition of a Rotary kinetic fluid motor.

(4) Note. An indeterminate motor (Black box) having internal generation not classified elsewhere is classified under this subclass.

123, Internal Combustion Engines, for motors wherein unburned hydrocarbons are cyclically introduced into an expansible chamber device, isolated therein and then ignited to increase the pressure of said isolated material. See Class 123

22, for motors which may operate as an internal combustion engine or a hot air motor, of the type herein classified, alternating between the two modes of operation either

selectively or as the result of a predetermined cyclic operation.
