Abstract: In a pneumatic position controller for controlling the position of a pneumatic servomotor (10) to a value determined by a pneumatic command pressure, the command pressure acts through a movable wall member (30) on a pivotable balancing member (40). The balancing member (40) controls through a baffle plate (52) the outlet nozzle (56) of a pneumatic amplifier (24). The balancing member (40) is axially spaced from a feedback lever (44), with aligned pivot axes. A helical torsion spring (50) has one end attached to the balancing member (40) and the other end attached to the feedback lever (44). The feedback lever (44) is rotatable by the servomotor (10). An advantageous and compact construction permitted by the use of the helical torsion spring (50) is described.
