Title:
THERMOSTATIC EXPANSION VALVE
Document Type and Number:
Japanese Patent JP2014126280
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve vibration control performance of a thermostatic expansion valve.SOLUTION: A thermostatic expansion valve includes a valve chamber in a valve body, and a valve element arranged in the valve chamber. An operation rod 60 operating the valve element is inserted into a through hole 70 of the valve body, and is driven by a power element. A seal member 80 is inserted into a seal member insertion hole 72, and the operation rod 60 is inserted into an inner peripheral hole 81. The through hole 70 is provided so as to be eccentric with respect to a center Cof the seal member insertion hole 72. Slide friction resistance between the operation rod 60 and the through hole 70 as well as slide friction resistance between the operation rod 60 and the seal member 80 occur to improve vibration control performance.
