Abstract

1,211,495. 211,495. Fluid-pressure servomotor systems. SOC. D'OPTIQUE PRECISION ELECTRONIQUE ET MECANIQUE. Feb.5, 1969 [April 26, 1968], No.6277/69. Heading G3P. A conventional two stage flapper valve Fig. 3 (not shown) controlled by an electromagnet is housed in a casing which also contains the elec - trical circuitry feeding the electromagnet. This circuitry includes a D.C. input 6 feeding a voltage stabilizer 7 providing a power supply to differential amplifier 8 in circuit with a comparitor 9 which is fed with a reference signal through lines 10, and a variable signal through line 11. The stabilizer also provides power supplies to the reference variable signal sources (not shown) through lines 12 and 13.
