Document Type and Number:
WIPO Patent Application WO/2022/070838
Kind Code:
A1
Abstract:
A valve device (10) is provided with a housing (12) and a plate-like fixed disc (14) in which at least one flow path hole (141, 142) for passing a fluid therethrough is formed. This valve device is provided with: a drive portion (16) for outputting a rotational force; a shaft (18) that rotates about a predetermined axis (CL) by the rotational force; and a rotor (20) for increasing/decreasing the opening degree of the flow path hole in accordance with the rotation of the shaft. The rotor includes: a plate-like drive disc (22) that slides while facing the fixed disc; and a lever (24) which is fixed to the drive disc and which couples the drive disc and the shaft to each other so as to be integrally rotatable while the drive disc can be displaced in the axial direction of the shaft. Between the shaft and the lever, a torsion spring (30) for biasing the lever toward the shaft in the circumferential direction about the axis of the shaft is arranged. The shaft is provided with abutting portions (187a, 188a) contacting the lever at different positions in the circumferential direction.
