摘要 |
A thermal expansion valve 10-3 includes a passage 32 through which refrigerant enters a prism-shaped body 30 from a receiver, and a valve means 32b placed within a valve chamber 35 for controlling the opening of an orifice 32a. The refrigerant returning from an evaporator 8 travels through a passage 34 toward a compressor 4. A power element 60 that drives the valve means 32b via a heat sensing shaft 36f comprises a disk-shaped housing 36d and a diaphragm 60a placed within said housing, which constitute a pressure working chamber 36b. A working gas is filled inside said pressure working chamber 36b and sealed thereto by a plug body 60k. The diameter size of the diaphragm 60a and the whole size of the plug body 60k are reduced in order to miniaturize and reduce the weight of the thermal expansion valve as a whole. <IMAGE> |
