Summary:PROBLEM TO BE SOLVED: To reduce noise of an electromagnetic valve with a differential pressure valve used in a heat pump cycle.SOLUTION: An electromagnetic valve with a differential pressure valve 100 includes an electromagnetic valve part 200 and a differential pressure valve part 300 integrally in a valve body 102. When the electromagnetic valve part 200 is electrified to a coil 240, a plunger 270 lowers to close a main valve seat 114 by a main valve body 210. Although a differential pressure valve body 330 opens or closes a differential pressure valve seat 312, the differential pressure valve part 300 includes a vibration spring 400 to prevent vibration of the differential pressure valve body 330 from occurring.
