Abstract (en)
[origin: EP3239520A1] A control valve (1) includes a solenoid (4) mounted on a body (5), and a pressure sensor (8) to detect a predetermined refrigerant pressure to be referred to for power supply control of the solenoid (4). The solenoid (4) includes a solenoid body integrally mounted on the body (5) in an axial direction, an electromagnetic coil (54) held by the solenoid body and having a working space on an inner side thereof, a core (46) fixed to the solenoid body coaxially with the electromagnetic coil (54), a plunger (50) supported in the working space such that the plunger (50) is displaceable in the axial direction, and a power supply line connected to the electromagnetic coil (54) and drawn out from a side of the solenoid body opposite to the body (5). The pressure sensor (8) includes a pressure sensing part that senses the refrigerant pressure and is displaced by the sensed refrigerant pressure, and an output line to output a detection signal depending on a displacement of the pressure sensing part. The pressure sensor (8) is positioned on a side of the electromagnetic coil (54) opposite to the body (5).
