Abstract (en)
[origin: ES283335U] The expansion valve has a valve lifter which has an axial capillary bore, a shoulder which abuts the membrane and a tapered end which passes through the membrane with clearance forming a gap. A plunger whose movement is controlled by a magnetic coil is used to close and open the capillary bore.
