Abstract
1445081 Fluid-pressure servomotor systems LUCAS INDUSTRIES Ltd 9 Aug 1973 [17 Aug 1972] 38327/72 Heading G3P A fluid-pressure control valve has a piston 16 with flow-control apertures 17 between an inlet 11 and an outlet 12, the position of the piston being controlled by the pressure in chamber 19. The latter is controlled by a pivoted valve-member 23 co-operating with the end of a passage 22 communicating with the inlet and positioned by the force of the solenoid coil 26 on the armature 25 and the adjustable spring-bias 27. Outlet pressure can thus be regulated according to the current in coil 26. In a modification the pivoted valve-member 23 is replaced by one in a cradle on the end of the armature co-operating with a side hole in an inlet tube. The piston armature may be replaced by a bellows or diaphragm. In another embodiment a torque motor acts on the spring-bias or the pivot shaft of a pivoting valve-member 23, the chamber 20 being adjustably vented.
