Abstract
PURPOSE:To prevent a refrigerating cycle from unstable phenomenons caused by the change of thermal load in reference to a heat-transmitting device of a heat- sensing cylinder of an expansion valve used for the refrigerating cycle by providing a metallic pipe or plate between the heat-sensing cylinder and a refrigerant pipe for increasing the thermal capacity. CONSTITUTION:A part 4 of the pipe wall of a metallic pipe 1 is gained for giving elasticity. The metallic pipe 1 is fitted on the periphery of a heat-sensing cylinder 2, and brought in contact with a refrigerant pipe 3 on its periphery. The increase of the thermal capacity by the metallic pipe 1 permits to increase the time constant of the thermal conduction between the heat-sensing cylinder 2 and the heat-sensing part of the refrigerant pipe 3 and prevent a refrigerating cycle from the generation of unstable phenomenons caused by the change of thermal load in an evaporator.
