摘要： An expansion valve includes a valve body having a valve body hole, a first passage, a bottomed valve chamber, a second passage, a third passage and a guide member disposed in the valve body hole between the first passage and the third passage. The valve body hole has a first valve body hole portion and a second valve body hole portion of different diameters forming a valve body step between the second passage and the first passage. The guide has a first guide portion and a second guide portion of different diameters forming a guide portion step. The guide is sized to be slidably received by the valve body hole in a close-fitting relationship with the first valve body hole portion receiving the first guide portion, the second valve body hole portion receiving the second guide portion and the valve body step and the guide portion step contacting each other.

摘要： An expansion valve 1 comprises a square-column-shaped valve body 10, and a spherical valve means 30 housed within a valve chamber 20 opposing against a valve seat 22. A working shaft 50 coming into contact with said valves means 30 connects to a stopper member 60, thereby transmitting to the valve means 30 the movement of a diaphragm 230 being displaced by the pressure change in a pressure chamber 240 of a power element 200. A lower housing 220 of the power element 200 is provided with an opening portion and claws, which enable the power element to be coupled to a mounting unit 100 formed to the top portion of the valve body 10. An elastic packing member 150 enables the element to be securely and airtightly coupled to the body. According to the present invention, the assembling of the valve is simplified and the manufacturing cost is reduced.
