  • Publication number: 20210102635
    Abstract: A valve device includes a valve, a drive device, a magnet coupling, and a screw mechanism. The valve includes a valve body and changes a flow mode of refrigerant flowing in a circulation path of a refrigeration cycle device. The drive device includes an electric drive unit as a drive source. The magnet coupling includes a driving-side rotary body and a driven-side rotary body that are magnetically connected to each other in a non-contact manner and transmits a rotary motion of the electric drive unit from the driving-side rotary body to the driven-side rotary body. The screw mechanism converts the rotary motion of the driven-side rotary body into an axial linear motion of the valve body. The valve device is configured to change the flow mode of refrigerant by using the linear motion of the valve body caused via the magnet coupling and the screw mechanism in response to the drive of the electric drive unit.
