ね定数より大きくしているからである。In this state, Ikkyu 111I1 Pilgrimage Route 4 and Nikudori Passage 4 are completely connected to each other. □ Now, if you supply pressure oil all the way through the Ikkushi route while moving the DC on-off renoid (uJ k in accordance with Pal No. 191), the pressure oil will flow out from the rJ secondary information DI & 4. Next - When the pressure in the pronation of the passage increases, that pressure acts on the pressure chamber QiK4 and the spool (8). The off-off solenoid moves against the spring member S while maintaining their relative relationship as shown in the figure. Only the first spring member can move while maintaining their relative relationship in this way. This is because the spring constant a of - is made larger than the spring constant of spring sm- of #&2.

l [L, maintain the pressure in the secondary hook passage 4 at the set pressure. The pressure in the tab pressure 1il- and the average suction force generated by the solenoid ON time ring and the suction force of the solenoid t91 eye body determine the pressure in the secondary passage pronation.

When the force due to the internal pressure and the spring force of the M21j spring member (b) are balanced, the positioning position is achieved by the ζ loop ◎In this way, the DC on-on solenoid (9) is positioned according to the pressure inside the spool, and the spool (Since the relative positional relationship with the 4th cylinder is also constant, the force due to the pressure inside the pressure 14I and the solenoid suction force can be balanced.

(At 9, the relative barrier force of the spool is kept constant at tK, and the average European gravity becomes constant regardless of the position of the spool.)
