Document Type and Number:
Japanese Patent JP7302468
Kind Code:
B2
Abstract:
To provide a valve device and a refrigeration cycle device, capable of controlling a plurality of valves while suppressing increase of the number of components.SOLUTION: A valve device 13 includes: a first valve 160 in which a throttle opening of a first internal flow channel 162 is changed according to a pressure of a control fluid introduced to a first pressure chamber PC1; and a second valve 180 in which a throttle opening of a second internal flow channel 182 is changed according a pressure of the control fluid introduced to a second pressure chamber PC2. The valve device 13 includes an actuator 130 for driving each of the first valve 160 and the second valve 180. The actuator 130 includes: a pressure regulation portion 131 for regulating the pressure of the control fluid; and a pressure introduction portion 132 for introducing the control fluid of which the pressure is regulated at the pressure regulation portion 131, to the first pressure chamber PC1 of the first valve 160 and the second pressure chamber PC2 of the second valve 180.SELECTED DRAWING: Figure 1
