Abstract (en)
[origin: EP1512926A2] An expansion device 1 allows to cancel part of the refrigerant pressure by a pressure-cancelling structure. Due to the pressure on a valve-closing pressure-receiving surface 27, the elastic force of a spring 18 is reduced. The spring 18 has a small size. The expansion device 1 is compact. When a differential pressure is equal or higher than a predetermined value, a relief mechanism relieves refrigerant from the upstream side through a valve element 20 into a separate passage, to prevent an abnormal inside pressure rise.
