PURPOSE:To make the axial direction of a valve gear itself possible for miniaturization, by installing a rotary magnet on a rotary shaft, while making a valve body into a rotary operation type in structure. CONSTITUTION:When each of solenoid coils 21 and 22 is impressed with a signal current so as to generate the same directional magnetic flux to both these coils 21 and 22, a parallel magnetic field from the coil 22 acts on a rotary magnet 20 via these magnet 20 and coil 21 and a body 12. Therefore, a rotary shaft 17, namely, a valve body 18 is rotated clockwise whereby an interconnecting through hole 13a is controlled to open or close proportionate to the impressed current. |
