Abstract

PURPOSE: To reduce a surging pressure by forming the valve seat of relief valve into a differential piston type and advancing the timing of poppet action.
CONSTITUTION: If electric current of a prearranged value is applied to a proportional electromagnet, a solenoid suction force acts on armature 17 and movable valve seat body 5 and poppet 13 are displaced to the left, compressing springs 14, 12. The movable valve seat body 5 and poppet 13 stop where the solenoid suction force and the power generated on the both springs 12, 14 are balanced. When the pressure of fluid circuit connected to the primary port 9 sharply climbs due to delay factors such as friction resistance on the circumferential surface of movable valve seat body 5, the fluid resistance of passage 8, etc., poppet 13 leaves the seat part 11 during a comparatively lower pressure transition and subsequently, movable valve seat body 5 pursues the poppet 13 at a speed to meet resistance. Therefore, the relief action is begun at a comparatively lower pressure.
