Document Type and Number:
WIPO Patent Application WO/2023/167284
Kind Code:
A1
Abstract:
A valve (11) comprises a housing, a hole (400), a hole (700), a valve diaphragm (80), a seat (43), and a projecting part (90). The housing has a housing member (70) and a flat plate (41) that face each other, and a side wall (42) that connects to the housing member (70) and the flat plate (41), and can define a valve chamber (410) together with the housing member (70) and the flat plate (41). The hole (400) is made in the flat plate (41), and communicates the valve chamber (410) with outside of the valve (11). The hole (700) is made in the housing member (70), and communicates the valve chamber (410) with outside of the valve (11). The valve diaphragm (80) has a through-hole (800) that divides the valve chamber (410) into a first space on the flat plate (41) side and a second space on the housing member (70) side, and allows communication between the first space and the second space. The seat (43) projects from the flat plate (41) into the valve chamber (410), and is disposed at a position overlapping with the through-hole (800) in a planar view of the valve (11) in a first direction in which the flat plate (41) is viewed from the housing member (70). The projecting part (90) is disposed between the hole (400) and the seat (43) in a cross-sectional view of the valve (11) in a second direction orthogonal to the first direction, and is provided on the valve diaphragm (80) or the flat plate (41) in the first space.
