摘要： An expansion valve adapted to achieve a stable operation in case of variations of the pressure of a high-pressure refrigerant is actuated by a power element transmitting an opening force to a valve body via a rod located between the power element and the power body by applying couple forces to the rod and generating a retarding force for the rod while the rod is guided in the direction of its shaft line
