FLUID CONTROL VALVE

PROBLEM TO BE SOLVED: To provide a fluid control valve capable of shortening the length of the fluid control valve in the axial direction of a spool. SOLUTION: This fluid control valve has the spool 20 slidably stored in a sleeve member 10, and springs 23a and 23b energizing the spool 20 in the slid...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fluid control valve capable of shortening the length of the fluid control valve in the axial direction of a spool. SOLUTION: This fluid control valve has the spool 20 slidably stored in a sleeve member 10, and springs 23a and 23b energizing the spool 20 in the sliding direction. The fluid control valve has an intermediate part 20c (a ferromagnetic substance part) formed in the spool 20 so as to extend in the axial direction of the spool 20, permanent magnets 50a and 50b oppositely arranged by sandwiching the intermediate part 20c in the orthogonal direction to the axial direction of the spool 20, forming oppositely turning magnetic fields juxtaposed in the axial direction between mutual ones and formed longer than the intermediate part 20c in the axial direction of the spool 20, and coils 40a and 40b arranged in the orthogonal direction to the axial direction of the spool 20 to the permanent magnets 50a and 50b and generating the magnetic fields by current-carrying so as to penetrate through the opposed permanent magnets 50a and 50b.
