<P>PROBLEM TO BE SOLVED: To provide an electromotive switch valve which can selectively open and close a valve hole which leads to a plurality of gas outflow ports, and can suppress the weight increase and cost increase of an appliance when applied to a gas appliance equipped with a plurality of gas burners. <P>SOLUTION: An electromotive switch valve MV in which a gas inflow port 21 and a plurality of gas outflow ports 22 are formed, concurrently has a gas valve casing 2 having a plurality of valve holes 25 communicating respectively with the plurality of gas outflow ports, and is equipped with a movable body 4 moved by a first motor M1 and a plurality of valve body 3 which opens and closes respectively the plurality of valve holes. To the movable body 4, there is mounted a plurality of electromagnets 5 which absorbs respectively an armature 33 attached to the plurality of valve bodies 3, an energizing means 6 being interposed normally in the upper end position. In the upper part of the movable body, a rotary plate 9 rotated by a second motor M2 around an axis concentric with the movable body is provided so that a plurality of pressing parts 93 may be formed in the lower face of the rotary plate with a predetermined positional relation, and is set so that the combination of the magnets pressed down by the rotation of the rotary plate may change. <P>COPYRIGHT: (C)2012,JPO&INPIT |
