摘要:
An electromagnetic valve according to one embodiment includes a body having a lead-in port through which a refrigerant is led in, a lead-out port through which the refrigerant is led out, and a valve hole formed in a passage joining the lead-in port to the lead-out port, a main valve element that opens and closes a valve section by moving toward and away from the valve hole, and a solenoid that supplies a drive force in a direction of axis line to the valve element, the solenoid being mounted on the body. The main valve element has a pilot passage that is open to the valve hole and an orifice that throttles and expands the refrigerant led in from the lead-in port so as to be led out to the pilot passage, the orifice being so formed as to communicate between the lead-in port and the pilot passage.
