Abstract

1477282 Fluid-pressure servomotor systems W VOLKI 12 Feb 1975 [6 March 1974] 6067/75 Heading G3P In a solenoid operated piston valve a throttle 11 is provided in the passageway 6 leading to a work port. When solenoid 8 is actuated to shift the valve to the left the pressure on each side of the throttle is fed to respective ends of the valve to produce a resultant force opposing the opening force of the solenoid. In an alternative embodiment, Fig. 2 (not shown) the throttle is provided within an axial passage in the piston valve. In a further embodiment, Fig. 3 (not shown) passages are provided in the piston so that in the neutral position the inlet (28) is connected to exhaust (24).
