<p>PURPOSE:To enable the open degree of a throttle valve to control in proportion to an input current value by changing a reciprocal motion of a movable core due to magnetic force of a linear rotary solenoid for the carbureler of a car to a rotary motion through a cam mechanism. CONSTITUTION:Energizing a coil 20, the parts of a first yoke 2, a movable core 9, a second yoke 3, a circular body 16 and a housing 1 composite a magnetic force line circuit and a shaft 8 is sucked right together with the movable core 9. A ball 21 rolles between cam grooves 14, 5 and a disc 13 receives a counterclockwise torque through side thrust generated on the slant faces of both the cam grooves. The torque rotates the shaft 8 against a coil spring 15 generating a rotary torque. The movable core 9 moves right the distance corresponding to the input supplied to the coil 20 and so that the rotary angle of the shaft 8 is proportional to the input.</p> |
