Title:
VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/235508
Kind Code:
A1
Abstract:
This valve device comprises a valve, a drive device, a magnetic joint, and a screw mechanism. The valve comprises a valve body and changes the flow mode of a refrigerant flowing within a circulation path of a refrigeration cycle device. The drive device comprises an electric drive unit as a drive source. The magnetic joint comprises a drive-side rotating body and a driven-side rotating body that are magnetically coupled to each other without being in contact, and rotating motion of the electric drive unit is transmitted to the driven-side rotating body from the drive-side rotating body. The screw mechanism converts the rotating motion of the driven-side rotating body into linear motion in the axial direction of the valve body. The valve device is configured so that the flow mode of the refrigerant is changed by linear motion of the valve body obtained as a result of the driving force of the electric drive unit passing through the magnetic joint and the screw mechanism.
