PURPOSE:To obtain a four port connection valve for a refrigerating cycle with high reliability as to switching operation and operable for switchover at all times by providing a solenoid to be used for moving cylindrical sliders for switching refrigerant passages in the axial direction of the cylinders. CONSTITUTION:Cylindrical sliders 24, 25 for switching respective refrigerant passages 21, 22, 23, 17 include a stem 35 having one end fixed through a spring 34, and a solenoid coil 32 is disposed around the stem 35. Therefore, in the above four port connection valve for a refrigerating cycle, energization of the solenoid coil 32 causes the stem 35 to be pulled up, permitting free valve operation even when the air conditioner is stopped, and furthermore improved reliability is obtainable because of its electromagnetic control.
