Abstract

PURPOSE: To reduce a generation of fluid fixing phenomena in a spool by a method wherein entire circumference of the spool is positioned in an annular groove and nonbalanced operating force produced in a radial direction of the spool is reduced.
CONSTITUTION: Inner circumferential ends 21A, 21F of the side walls forming a change-over groove are positioned in the balance grooves 19E, 19C at the land outer circumferential surfaces over their entire circumferences, and the inner circumferential ends 21E, 21C at a low pressure side connecting with oil reservoir are also positioned in the balance grooves 19A, 19F. Therefore, no nonbalanced operating force is generated near the lands 9, 10 where the inner circumferential ends 21A, 21F are positioned, a solenoid device is deenergized from this change-over condition and so a fluid fixing phenomenon a spool is not generated even if the spool is to be returned to its intermediate condition under a nonstriking weak spring 13.
