Abstract
1445082 Fluid-pressure servomotor systems LUCAS INDUSTRIES Ltd 9 Aug 1973 15475/76 Divided out of 1445081 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 relief valve 46 downstream of an adjustable throttle 44 in a passage 43 communicating the inlet with the chamber 19. The spring-bias 47 of the relief valve is adjusted by the output arm 49 of a torque motor 50 so that the outlet pressure is regulated according to the current in the torque motor.
