Abstract

943,650. Fluid-pressure servomotor control systems. J. C. ECKAKDT A.G. Feb. 14, 1961 [Noy. 25, 1960], No. 5457/61. Heading G3P. A pneumatic controller comprises a measured value bellows 11, a desired value bellows 12 and a pair of feedback bellows 13, 14, the inner ends of which are fixed to a support 15 and the outer ends of which act on the internal surface of a ring 16 the outer surface of which cooperates with a nozzle 18 rotationally adjustable with respect to a scale 19. If desired the inner surface of the ring may cooperate with the nozzle and the bellows may be inclined to the axes shown. In another example the outer ends of the bellows are fixed and their inner ends act on a ring which co-operates with a nozzle.
