Abstract

602,837. Fluid-pressure servomotor-control systems. GROUPEMENT FRANCAIS POUR LE DEVELOPPEMENT DES RECHERCHES AERONAUTIQUES. Nov. 8, 1945, No. 29854. Convention date, Sept. 24, 1941. Drawings to Specification. [Class 135] [Also in Groups XXVII and XXVIII] In a two-stroke internal-combustion engine cylinder having two exhaust valves the timing of one of which is adjustable, the pressure in the exhaust pipe is maintained constant as the altitude increases by a valve therein which is moved by a piston operated by pressure fluid, controlled by a bellows subject to exhaust pipe pressure.
