摘要： An exhaust gas purifying system for internal combustion engines includes a three-way catalyst disposed in the exhaust system of the engine, and secondary air is supplied to the exhaust system through an air control valve under the control of an air-fuel ratio control circuit. The air-fuel ratio control circuit produces a control signal which increases or decreases stepwisely at every reception of a clock signal depending on whether the air-fuel ratio in the exhaust system is above or below a stoichiometric air-fuel ratio. The air control valve is of the proportional electromagnetic type and controls the secondary air passing therethrough in proportion to the control signal.

摘要： An electromagnetic rotary driving device including a rotor of a permanent magnet arranged in a hole formed in a bored stator core block of a stator core, made from magnetic material. The air gap formed between the bored block of the stator core and the rotor in the direction parallel with the magnetic path in the stator core is relatively long, while the air gap formed between the bored block of the stator core and the rotor in the direction perpendicular to the magnetic path in the stator core is relatively short. In this device, the angle of rotation of the rotor is continuously changed by the current flowing through the coil of the stator without requiring a spring for return motion.

摘要： A rotary solenoid actuator for proportionally controlling the flow of fluid, such as air, in a pipe comprises a housing with a rotor rotatably mounted thereon. A stationary coreless coil for generating a magnetic field in response to a control current therethrough is mounted in the housing. A permanent magnet is affixed to a rotatably mounted shaft within the coil, and a return spring is attached to the rotating shaft. Due to low hysteresis in the coreless coil, there is a linear relationship between the control current and the fluid flow.

摘要： A rotary driving apparatus suitable for use for a flow control valve provided with a rotor valve rotatably mounted in a housing. The rotor valve is connected to a permanent magnet member. The permanent magnet member is arranged adjacent to a pair of diametrically spaced ends of a core on which a coil is wound so that the ends are oppositely magnetized to provide a two pole electric motor, stopper means is provided for allowing limited rotary motion of the rotor between a first position and a second position. The permanent magnet member is so arranged with respect to the ends of the core that a torque is, during the de-energization of the coil, generated in order to engage the stopper means. Thus, the first or second position of the rotor valve is maintained without energization of the coil.
