<p><P>PROBLEM TO BE SOLVED: To prevent the movement of a spool of a solenoid spool valve caused by fluctuations in pressure. <P>SOLUTION: A valve 14 for a solenoid valve includes a valve body 30 having a channel 32 in the vertical direction; and the valve body 30 includes a supply opening 31c, a control opening 31b, and a discharge opening 31a. The spool 36 is slidably arranged in the channel 32 in the vertical direction, and the spool 36 adjusts the connection between the supply opening 31c and the control opening 31b by exterior excitation. Then a pressure adjustment device 40 is connected to the discharge opening 31a, the control opening 31b, and the supply opening 31c so that it is operated, and adjusts at least one connection of the discharge opening 31a with the control opening 31b, and with the supply opening 31c. Then the pressure adjustment device 40 almost maintains the position of the spool 36 regardless of the fluctuations in pressure between the control opening 31b and the supply opening 31c. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
