Japanese Patent JP7136455

B2

To provide a fluid control valve which is stabilized in performance.SOLUTION: A valve seat face 56 is formed into a cylindrical shape at an inner wall of an inner sleeve 50. A retard supply opening part ORs makes the outside of the inner sleeve 50 and the valve seat face 56 communicate with each other. A spool 60 can control a flow of a working fluid between a working fluid supply source and a retard chamber, and between the working fluid supply source and an advance chamber according to a position in an axial direction with respect to the inner sleeve 50. A retard supply check valve 71 has a valve main body 700 which is formed into a cylindrical shape, and whose external peripheral wall can abut on the valve seat face 56, and a lock part 91 formed at the external peripheral wall of the valve main body 700, and is valve-opened by being contracted in a diameter so that the external peripheral wall of the value main body 700 separates from the valve seat face 56, and valve-closed by being expanded in the diameter so that the external peripheral wall of the valve main body 700 abuts on the valve seat face 56. A rotation regulation part 95 is formed at the valve seat face 56, and can regulate the rotation of the retard supply check valve 71 with respect to the inner sleeve 50 by locking the lock part 91.SELECTED DRAWING: Figure 4
