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 (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.

摘要： A motor operated valve control device (202) is connected with a motor operated valve (1) that adjusts a valve opening degree by rotating a rotor (60). The motor operated valve control device (202) includes a rotation detecting unit (216) that detects a rotation angle of the rotor (60), and a rotation control unit (218) that moves the rotor (60) toward a predetermined initial position (stop position) (Q) by providing instructions on a rotating speed and a rotating direction of the rotor (60). In control of movement of the rotor (60) to the initial position (Q), the rotation control unit (218) lowers the rotating speed of the rotor (60) when a difference between a rotation angle at an origin position (P0) of the rotor (60) and a detected rotation angle of the rotor (60) is sufficiently small.
