Abstract
An expansion valve of the degree-of-supercooling control type can be easily adjusted when assembling the degree of supercooling of a high-pressure refrigerant control to be held constant if an exerting force adjusting member is used for finely adjusting the exerting force. If either a throttling portion or a valve seat is formed with the exerting force adjusting member, a simple and compact design or construction can be achieved.
