<p>PURPOSE: A valve for sealing a passage is provided to have a simple and miniaturized structure and to endure high pressure load in spite of high pressure differences and pressure variations. CONSTITUTION: A valve for sealing a passage comprises a valve housing(1), a valve disc(8), and a drive(12). The valve housing has a first wall(2) having a first opening(3). The opening has a geometrical opening axial line(4) and a valve seat(5) surrounding the first opening above a first lateral side(20) of the valve housing. The valve disc has a ring or frame-shaped outer disc portion(9) and a closed inner disc portion(11). The drive is connected to the outer disc portion and is positioned in a part where the valve disc is arranged alongside the first opening.</p> |
