Abstract

704,829. Fluid-pressure servomotor-control systems. HOBSON, Ltd., H. M., and GREENLAND, L. S. Jan. 21, 1953 [April 7, 1952], No. 8830/52. Addition to 698,281. Class 135 In a servomotor system according to the parent Specification, the control valve 26 serves to vary differentially the restrictions in both outlets from the ends of the servomotor housing. Also, the stem 13 of the servo-piston extends through both ends of the housing so that the effective areas of the faces of the piston are equal and the piston will be unaffected by variations in total inlet or outlet pressure.
