SOLENOID CONTROLLED MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a solenoid controlled mechanism operable by mechanical urging force in simple constitution without exerting a bad influence upon controlling characteristics by electromagnetic force. SOLUTION: This solenoid controlled mechanism is equipped with a needle 5 made of a magnetic material; a first magnetic path constituting a closed magnetic circuit containing the needle 5 in a first position of the needle 5 and holing the needle 5 in the first position; a second magnetic path constituting the closed magnetic circuit containing the needle 5 in a second position of the needle 5; and a coil 7 moving the needle 5 from the first position to the second position by negating the magnetic flux holding the needle 5 in the first position in the first magnetic path by electrical energizing force, and a mechanical control means comprising a control panel 23 moving the needle 5 from the first position to the second position by mechanical urging force is installed.
