PURPOSE:To decrease a time of electric current conduction in a solenoid part and save energy, by holding a valve shaft of a solenoid driven selector valve suitable for a room cooler or the like through screw action. CONSTITUTION:An internal thread part 10 is provided to a passage 9 extending through the axial direction in a housing 8, and an external thread part 14 of a valve shaft 13 is rotatably fitted to the part 10. A rotor 19 in a stepping motor part 7 is integrally formed with the shaft 13, and the rotor 19 is rotated to laterally move the shaft 13, then a valve can be selected. In case of holding the shaft 13 to a prescribed position, the shaft 13 is held by screw action, and continuous conduction of an electric current is not necessary for a stator 22. |
