Japanese Patent JP2016090067
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a temperature type expansion valve capable of exhibiting excellent function, while preventing control hunting even in a low load of a refrigeration cycle.SOLUTION: In an expansion valve 1, a space surrounded by a body 2, a lower housing 27 and a diaphragm 28 forms a temperature sensitive chamber 54. In a partition wall 62 between a second passage 14 and the temperature sensitive chamber 54, a communication hole 56 is provided on a downstream side with respect to a shaft 33. With this constitution, refrigerant introduced from the second passage 14 to the temperature sensitive chamber 54 can be guided to the communication hole 56 along the wall surface of the downstream side end part of the temperature sensitive chamber 54, and derived to the downstream side of the second passage 14.SELECTED DRAWING: Figure 2
