ABSTRACT:
The expansion valve of the present invention comprises of a heat sensing shaft 36f equipped to the expansion valve 10 and a diaphragm 36a contacting its surface, a large stopper portion 312 for receiving the diaphragm 36a, a large radius portion 314 movably inserted to the lower pressure activate chamber 36c and contacting the back surface of the stopper portion 312 at one end surface and the center of the other end surface formed at the projection 315, and a rod portion 316 whose one end surface fit to the projection 315 of the large radius portion 314 and the other end surface continuing from the valve means 32b, wherein a concave 317 is formed on the outer peripheral of said projection 315. This concave 317 is the fitting means for fitting the resin 101 having low heat transmission rate to the heat sensing shaft in order to prevent the occurrence of hunting phenomenon.
