PROBLEM TO BE SOLVED: To provide an electrically driven change-over valve capable of realizing a reduction in size of an occupied space by an electrically driven valve while avoiding a large-sized formation of a coil and positively performing a sliding motion of a valve body in a rotation direction on a valve seat surface under application of a shape of well-balanced valve body.SOLUTION: This invention relates to an electrically-driven changeover valve comprising an inflow port P arranged to be opened on a plane of a valve seat surface 11a and outflow ports P1, P2 having a plurality of openings arranged to be spaced-apart by prescribed spacing and a valve body 23 rotated and slid on the valve seat surface 11a under driving force of a motor 12, and the rotating valve body 23 selectively opens or closes the plurality of outflow ports P1, P2. The valve seat 11a is fixed to a lower end opening part of a cylindrical housing 11. The valve body 23 has, at its central part, a disc-like valve body and has symmetrical flanges protruded to be arranged outwardly from the outer circumference of the disc, one of the flanges is applied as a stopper and the other flange is provided with a protrusion and the protrusion is fitted into a salient part formed at a gear device. |
