DEFINITION

Classification: 60/240

(under subclass 233) Apparatus in which the condition sensing means characteristic of the apparatus including means, responsive to a sensed condition change, to control both the flow of a fuel and a combustion supporting oxidizer (e.g., air).

(1) Note. Means to alter the flow of oxidizer include, e.g., air inlet control as by a diffuser having a variable opening, variable flow retarding baffles, air bleed means, liquid oxidizer valve means or pump control means, or compressor vane setting control means. Means which controls fuel flow or an exhaust nozzle opening, resulting in a change in compressor speed and thus a change in oxidizer flow is not included in this definition. For condition responsive fuel flow and exhaust nozzle area control see subclasses 235+, 241 and 243.

(2) Note. See glossary under subclass 205 for meaning of fuel and oxidizer.
