DEFINITION

Classification: 60/235

(under subclass 233) Apparatus in which the condition sensing means controls both the rate of fuel flow to combustion chamber means in the apparatus and the cross sectional area of a motive fluid ejecting means.

(1) Note. Included in this subclass are apparatuses having a fuel control means and a nozzle area control means each responsive to different sensed conditions, or both responsive to the same sensed condition.
