<p>PURPOSE: A fluid control valve is provided to shorten the length of a fluid control valve due to placing on the axial direction of a spool. CONSTITUTION: A fluid control valve comprises: a spool which moves with sliding in a sleeve member(10); a spring(23a,23b) which pressurize the spool to the sliding direction; a permanent magnet(50a,50b) which form magnetic field of the opposite direction by being arranged to face each other with a middle portion(20c) at the center; and a coil(40a,40b) which is arranged to the perpendicular direction of the axial direction of the spool about a permanent magnet. The middle portion is formed in the spool in order to be expanded to the axial direction of the spool. The coil generates magnetic field which passes through the permanent magnets facing each other with flowing current.</p> |
