弁割れしやす（なるという欠点がおった。However, when the valve support 041 is cylindrical as described above, the contact with the valve plate α becomes a line contact, and the effect of securely fixing the valve plate 031 to the valve chamber Qll is low, and the liquid compression of the refrigerant causes the valve plate (When an abnormally strong force is applied to I31 and valve support 041, there is a problem of wobbling.) Figure 2 shows another example of a conventional valve support. However, since the diameter of the corner 0υ along the support 0 is small, the valve plate is in strong (bent and The stress increases,
It had the disadvantage of being prone to valve cracking.
