摘要： A motor operated valve (100) includes: a feed screw mechanism including a guiding part (242) including an external thread portion (244), and a guided part (326) constituting a rotation shaft (326) of a rotor (320) and including an internal thread portion (328) to be engaged with the external thread portion; and a stopper mechanism including a stopper portion (820) on the guided part, and a stopping face (830) on the guiding part. When a valve element (204) is driven by a motor (300) in the valve opening direction, the stopping face stops the stopper portion to restrict the movement of the rotor in the valve opening direction. The guided part includes an enlarged-diameter portion (334), which is open toward the body (200), at a position away from the internal thread portion. The stopping face is located on the inner side of the enlarged-diameter portion depending on the driving state of the rotor.

摘要： A control valve (1) includes a shaft (68) driven in a direction of an axis line to transmit a driving force of a solenoid (3) to a valve element (24), and a vibration absorbing member (100) having viscoelasticity and being set between a shaft support member (72) and the shaft (68). During stationary control of a valve opening degree, the vibration absorbing member (100) dynamically deforms following vibration of the shaft (68) accompanying PWM control. A material and a structure of the vibration absorbing member (100) are set such that, during the stationary control, a vibration amplitude of the shaft (68) is included in a range in which the vibration absorbing member (100) and the shaft (68) are not caused to slide relative to each other.

摘要： A motor operated valve control device (200) controls a motor operated valve (1) including a stepping motor (3) for rotating a rotor (60) by a driving current applied in accordance with an excitation pattern associated with a step, and a mechanism (109) for changing a valve opening degree by rotational movement of the rotor (60). The motor operated valve control device (200) includes an offset value storage unit 222 that stores a step number offset value set for each individual motor operated valve (1), a reception unit (210) that receives a step movement command, a rotation controlling unit (218) that corrects a step number, which is sequentially switched on the basis of the step movement command, on the basis of the step number offset value, and identifies an excitation pattern associated with the corrected step number, and a rotation instructing unit (214) that applies a driving current to the stepping motor (3) in accordance with the identified excitation pattern.

摘要： A motor operated valve (1) includes a body, a valve element, a rotor (320), a can (302), and a stator unit (360). The stator unit (360) includes a case (400) having a cylindrical shape and made of resin, a stator (340) mounted in the case (400) and coaxially around the can (302), a circuit board (420) mounted in the case (400), a power supply terminal (422) connected with the circuit board (420), a connector part (402) made of resin and integrally including the power supply terminal (422) therein, and a cap member (440), the cap member (440) and the case (400) forming a space (S) containing the circuit board (420). The connector part (402) is formed integrally with the case (400). A first seal portion is provided between a first open end portion (403) of the case (400) and the cap member (440), and a second seal portion is provided between a second open end portion (410) of the case (400) and the body.

摘要： A motor operated valve (100) includes a feed screw mechanism and a stopper mechanism. The feed screw mechanism includes a guiding part (242) mounted vertically on a body (200) and including an external thread portion (244), and a guided part (326) made of a cylindrical member constituting a rotation shaft (326) of a rotor (320), and including an internal thread portion (328) to be engaged with the external thread portion. The stopper mechanism includes a projection (250) formed on the outer surface of the guiding part, and a stopper member (500) removably mounted on the guided part, and including a stopper (506) sticking out radially inward of the inner surface of the guided part. When a valve element (204) is driven by a motor (300) to move in a valve opening direction, the stopper is stopped by the projection in a rotor rotating direction, so that the translational movement of the rotor is restricted.
