Abstract

519,778. Fluid-pressure servomotor-control systems, ASKANIA - WERKE AKT. - GES., (formerly ASKANIA-WERKE AKT-GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU). Sept. 19, 1938, No. 27323. Convention date, Sept. 30, 1937. [Class 135] A fluid-pressure servomotor-control system, more particularly for water level regulation, comprises a main servomotor 17 which is provided with a relay, e.g., a piston valve 16, controlled by an auxiliary servomotor 2 having a small pressure-fluid volume relatively to that of the main servomotor. The auxiliary servomotor 2 is itself controlled by a relay 12 and the pressure fluid circuit 1, 1 thereof is provided with a known,isodromic restoring device 4. A rigid restoring device is interposed between the main servomotor 17 and its relay 16, said device consisting of a cam 22 which is oscillated by movement of the piston 21 of the servomotor and is in engagement with the spring-pressed end 23 of a lever 19 jointed respectively to the said relay and to the rod of the piston 3 of the auxiliary servomotor 2. A modified connection between the piston 21 and cam 22, for use with a vertical servomotor cylinder 17, is also described.
