Title: Temperature control valve
Inventor: HONDA SHIN
IPC: F16K31/70
Filed: 2018-04-11
Abstract: To provide a temperature control valve which can control the displacement of a valve body by a temperature sensing part which is constituted of a shape memory alloy irrespective of a magnitude of a pressure difference of a refrigerant between before and after the refrigerant passes through the valve body.SOLUTION: Since a valve body 105 is accommodated in a hollow part 115 of a sleeve 103 and pressure equalization holes 125, 130 and 131 are formed, the pressure of a refrigerant flowing out of an opening part 118 of the sleeve 103 does not act as an opening/closing force of the valve body 105. Therefore, a constitution for coping with the pressure difference of the refrigerant between before and after the refrigerant passes through the valve body 105 is unnecessary. Accordingly, the displacement of the valve body 105 can be controlled within a range of a force which is exerted by a shape memory spring 106 irrespective of a magnitude of the pressure difference of the refrigerant between before and after the refrigerant passes through the valve body 105.SELECTED DRAWING: Figure 1
