摘要： A small-sized motor operated valve is disclosed that has high output and high resolution by housing a reduction gear together with a rotor in a single can. A valve shaft 32 having a valve member 30 is inserted to a motor operated valve body 10. A rotor 170 is disposed inside a can 100 attached to the body 10, and inside the rotor 170 is housed a reduction gear 200. The output of the rotor is input to a sun gear 220 and transmitted to planetary gears 230. The planetary gears 230 are engaged both with the fixed gear 250 and the output gear 260, and the output gear 260 is driven at reduced speed by a large reduction ratio. The output of the output gear 260 is transmitted via a driver 300 to a screw shaft 320, where it is converted into a linear movement and transmitted to the valve shaft 32.

摘要： A motor-operated valve includes a driving unit including a rotor and a stator, a feed screw mechanism, and a valve main body unit. In order to remove backlash intrinsic in the feed screw mechanism, a coil spring that urges a valve body in a direction away from a valve seat is arranged in a valve chamber. A spring bearing that forms a housing, in which the coil spring is housed, in the valve chamber is provided. Therefore, the large valve chamber is secured in the valve main body unit and passing sound is reduced when a fluid passes the motor-operated valve. Contact surfaces of the valve body and the coil spring can be aligning curved surfaces that absorb a bend of the coil spring.

摘要： A motor-operated valve has a rotor unit in a can, and is rotationally driven by a stator unit. The rotation of the rotor unit is transmitted to a screw feed member. A stem member fixed to a valve body is engaged threadedly with the screw feed member by a first screw portion. At the same time, the screw feed member is engaged threadedly with an external thread portion fixed to a valve stem by the second screw portion. The first screw portion and the second screw portion constitute a differential screw mechanism, and feeds the valve stem according to a difference in pitch.
