SPOOL VALVE BODY STRUCTURE

摘要

PROBLEM TO BE SOLVED: To miniaturize a spool valve body to be used for a hydraulic control device. SOLUTION: A spool valve body 31 is provided with a spool valve chamber 32 provided with a sleeve 35 in which a spool valve 36 is freely slidably stored and an oil introduction passage 33 which communicates with the spool valve chamber 32 via a communicating path 35a and has an axis parallel to an axis of the spool valve chamber 32. In this body 31, the spool valve chamber 32 and the oil introduction passage 33 are formed so as to overlap a part from the viewpoint of the axial direction of the spool valve chamber 32 and the communicating path 35a is formed in the sleeve 35.
