Title:
VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/075086
Kind Code:
A1
Abstract:
A valve device comprising: a housing forming a fluid flow path (111) through which a fluid flows; a fixed valve (40); and a drive valve (30). The fixed valve has an axis (S). Assuming that a direction in which the axis extends is an axial direction, the fixed valve is arranged in the fluid flow path, and forms first flow paths (41, 42) for causing the fluid to flow and a penetration chamber (43) penetrating the fixed valve in the axial direction. The drive valve is arranged on one side of the fixed valve in the axial direction in the fluid flow path, and forms a second flow path (31) for causing the fluid to flow. The drive valve is configured to rotate about the axis while sliding on the fixed valve, to thereby cause the second flow path to communicate with the first flow path. The housing is provided with a bottom portion (110) formed so as to cover the penetration chamber from the other side in the axial direction. In addition, an upstream-side flow path (112) included in the fluid flow path and arranged on an upstream side of the drive valve and the fixed valve in the flow direction of the fluid and the penetration chamber communicate with each other through a communication path.
