Abstract

PURPOSE: To lessen clearance between magnet and iron core, to enlarge adsorptive force of a bobbin and to diminish leak of fluid by forming the bobbin with use of ceramic material.
CONSTITUTION: A bobbin 17 is made of ceramic, clearance between iron core 16 and permanent magnets 19, 20, and leak of fluid is minimized. In the normal time, magnetic flux yielded from the permanent magners 19, 20 forms a magnetic circuit in the closed loop through the iron core 16 and a yoke 18, one part of which is conducted to an electromagnetic coil 18 wound up around said bobbin 17. With this condition, when electric current is applied to the electromagnetic coil 18, according to Fleming's left hand law, force is produced on the right side, the bobbin 17 is actuated and displaced to the right side resistingly to coil springs 25, 26, a conducting bore 22 which conducts the inlet port 11 of the body of a magnetic material 13 to the outlet port 12 is made its opening, atmospheric flow rate to be flowed into the negative pressure source is controlled in proportion to the size of applied electric current value.
