Abstract

946,188. Fluid-pressure servomotor control systems. RECHERCHES ETUDES PRODUCTION R.E.P. July 13,1962 [July 17, 1961], No. 27114/62. Heading G3P. [Also in Division F2] In a relay valve as described in Specification 928, 616 axial movement of the rigid shaft within the torsien tube 2 is prevented by two rods 9, 10 fixed to the end of the shaft and to the housing 11.
