Abstract

PURPOSE:To obtain a solenoid hydraulic valve, in which a control pressure can be controlled in accordance with a control current despite a change of supply pressure, by forming all the land parts of a spool in an equal diameter and eliminating a difference between the land parts in their pressure receiving area. CONSTITUTION:In order to perform a throttle control of a pressure of fluid, forming an annular clearance (h) in a facing surface between valve housing 1 and land parts 9, 10 of a spool 8, the annular clearance (h) is provided in a step difference recessed part formed in a side of the valve housing 1. Consequently, the spool 8, enabling its land parts 9, 10, performing the throttle control of the pressure of fluid, to be designed into a diameter D1 equal to a diameter D2 of the other land parts, eliminates a difference between the respective land parts in their pressure receiving area.
