VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/070839
Kind Code:
A1
Abstract:
This valve device comprises a housing (10), a flow hole formation part (20), a rotator (30), and a drive part (40). The housing (10) has a flow path through which a fluid flows. The flow hole formation part (20) is fixed to the interior of the flow path of the housing (10), and has a plurality of flow holes (21–24) through which the fluid passes and partitioning parts (25) provided between adjacent flow holes (21–24). The rotator (30) is provided so as to be able to rotate about a predetermined rotation axis (Ax), and has a flow path opening part (31) and a closed part (32). A virtual circle (C) is defined as being centered on the rotation axis (Ax) of the rotator (30) and perpendicular to the rotation axis (Ax). The partitioning parts (25) of the flow hole formation part (20) each have a parallel part (26) formed parallel along the radial direction of the virtual circle (C), and a gradually changing part (27) provided on the radially outer side of the parallel part (26) and formed so that the circumferential width gradually increases toward the radially outer side.
