PROBLEM TO BE SOLVED: To provide a motor-operated control valve device capable of sufficiently reducing noises generated by the rupture of bubbles or a turbulent flow of a refrigerant. SOLUTION: The motor-operated control valve device is equipped with a refrigerant flow-in part 10a, a flow control part 10c having a valve element 4 and a valve seat 9, a refrigerant flow-out part 10b, and a stepping motor 3 having a stator core 1 and a magnet 2, wherein a passage shaped approximately along a straight line is formed of the refrigerant flow-in part 10a, the flow control part 10c, and the refrigerant flow-out part 10b, and the flow control of the refrigerant is conducted by adjusting a degree of an opening between the tip of the valve element 4 and the valve seat 9 by moving the valve element 4 in the direction of the straight line accompanied by the rotation of the magnet 2 of the stepping motor 3. A passage dividing part 12 to divide the refrigerant passage is formed in at least either of the refrigerant flow-in part 10a and the refrigerant flow-out part 10b. COPYRIGHT: (C)2007,JPO&INPIT
