PROBLEM TO BE SOLVED: To provide a motor-operated valve always capable of performing the stable valve behavior at any time when performing the operation of a valve body which moves in an axial direction, from the fully opened state of the valve to the closed state or from the fully closed state of the valve to the opened state.SOLUTION: A motor-operated valve for opening/closing a valve body 32 by converting the rotary motion of a rotor 2 into the linear motion comprises: a stopper member 18 disposed movably in an axial direction and between a member 14 on the movable side and the valve body 32; and an elastic body 10 disposed between the stopper member 18 and the valve body 32. When the valve body 32 is at the valve opened state, the elastic body 10 is pressed in a direction to be compressed through a member 8 on the fixed side which is immovable in an axial direction; and by the reaction of the elastic body 10 at this time, the motor-operated valve is configured to act a force to loosen a screw feed mechanism.SELECTED DRAWING: Figure 1 |
