VALVE DEVICE

Japanese Patent JP3864008

B2

PROBLEM TO BE SOLVED: To enhance the responsiveness of valve opening and closing operation by arranging a shaft member axially movable according to the oration of a rotor on the center part of the rotor having a plurality of permanent magnet magnetic poles arranged in a position corresponding to each coil of a stator on the circumferential surface, and opening and closing a valve member by the movement of this shaft member.
SOLUTION: When DC is applied from a power source through a first brush 35, the DC is rectified by a commutator, carried to a spring, and supplied to a stator 22 side through a second brush 36. At this time, a rotating force is generated in a rotor 28 by the magnetic flux generated in a coil 24 to which the current is passed and the effect of the permanent magnetic pole 29 of the rotor 28, and a disc 31 is also rotated by this rotating force. Therefore, the contact position of the first brush 35 with the commutator is switched to continuously rotate the rotor 28. A shaft member 30 screwed to the screw hole 28a of the rotor 28 is moved to a valve part 46 side by the rotation of the rotor 28 to separate the valve member 45 from a seal member 41, whereby a valve device is laid in opened state.
