摘要： An expansion valve unit having a pressure detecting function includes a supercooling control expansion valve disposed in a flow path of a refrigerant sent into an evaporator of a refrigeration system constituting a refrigerating cycle to control the flow rate of the refrigerant. A pressure detector is provided at one end of the supercooling control expansion valve to detect the pressure of the refrigerant sent thereto through a passage in the expansion valve. The supercooling control expansion valve and the pressure detector are integrated with each other by a joining means.

摘要： In a pressure controlling valve 3 for causing deformation of a resilient member 32 by a pressure difference between a CO2 gas pressure in a sealed space (heat sensitive portion) corresponding to a refrigerant temperature and a high pressure of the CO2 refrigerant in the refrigeration cycle to open and close the valve, a volume ratio Vs/(Vs−Vo) of a total volume (Vs) of the sealed space when the valve is fully closed and a total volume (Vo) of the sealed space when the valve is fully open is greater than 1.9 or 2.4. To improve this volume ratio, a cavity 31d communicating with the sealed space is formed inside a displacement transmission member 31 coupled with the resilient member, or a recess portion 35a is formed in a cover member 35a, or a member communicating with the sealed space is connected.

摘要： An expansion valve 1 integrated with a solenoid valve includes a valve body 10 and a valve chamber 20 formed inside the valve body 10 to which a high-pressure refrigerant is introduced. A valve member 30 forms a throttle flow path between a valve seat 40, and controls the amount of refrigerant flowing therethrough. The valve body 30 is operated by the movement of a stopper member 80 of a power element 60 via an actuating rod 100. The high-pressure refrigerant acts on a surface 80a of the stopper member 80 opposite to a diaphragm 70 via a pressure equalizing passage 12, a connecting chamber 22 of a solenoid valve 200, and a pressure equalizing passage 14. The stopper member 80 is sealed between the guide member 90, so that the high-pressure refrigerant does not act directly on the diaphragm.
