PURPOSE:To simplify structure and go without so much requiremtn for precision of parts by providing a slide valve on the tip of a screw rod making screw engagement with a motor rotor of a solenoid four-ways selector valve used for refrigerant circuit switching and having valve holes opened and closed. CONSTITUTION:Piping connection ports 51-54 are provided on a cylindrical valve main body 21 and a freely sliding slide valve 16 is engaged with a valve seat 33 having opening connection ports 52-54. A screw rod 23 connected to the slide valve 16 is screw engaged with a motor rotor 22. When a coil 26 is set conductive and the rotor 22 is rotated, the screw rod 23 makes a longitudinal movement so that the piping connection ports 53,54 are subjected to switching connection. |
