Patent number: 11739853Abstract: A ventilation component includes a valve body portion, a shaft portion, a ventilation path, and a gas-permeable membrane. The shaft portion extends in a normal direction of the valve body portion. The shaft portion supports the valve body portion. The ventilation path extends through the shaft portion. The gas-permeable membrane closes the ventilation path. In a state where the ventilation component is fixed to a housing, a flow of gas passing through a peripheral opening is blocked by the valve body portion, and ventilation occurs between an inner space and an external space via the gas-permeable membrane. When a pressure difference obtained by subtracting a pressure of the external space from a pressure of the inner space is equal to or higher than a predetermined value, the valve body portion elastically deforms to be away from an outer surface to release the pressure of the inner space.Type: GrantFiled: January 24, 2020Date of Patent: August 29, 2023Assignee: NITTO DENKO CORPORATIONInventors: Yusuke Nakayama, Youzou Yano, Tomoyuki Kasagi, Akira Miyagaki

Patent number: 11560962Abstract: A ventilation component (1a) is to be attached to a housing (2) at a ventilation opening (5). The ventilation component (1a) includes a gas-permeable membrane (10), a ventilation valve (20), and a structural member (30). The structural member (30) has an inner space (40), and at least one of a first ventilation path (51) and a second ventilation paths (52). The inner space (40) is a space accommodating the gas-permeable membrane (10) and/or the ventilation valve (20). The first ventilation path (51) allows the inner space (40) to communicate with an external space of the ventilation component (1a). The first ventilation path (51) has a first inner opening (51i) and a first outer opening (51e), and the first inner opening (51i) faces the first outer opening (51e). The first inner opening (51i) and the first outer opening (51e) are present along a plane parallel to an outer surface (2s) of the housing.Type: GrantFiled: October 17, 2019Date of Patent: January 24, 2023Assignee: Nitto Denko CorporationInventors: Yusuke Nakayama, Youzou Yano, Akira Miyagaki

Patent number: 11536383Abstract: A ventilation component (1) includes a gas-permeable membrane (10), a ventilation valve (20), and a structural member (30). The ventilation component (1) is to be attached to a housing (2) having a ventilation opening (5). The ventilation valve (20) includes an elastic body, and is opened and closed by elastic deformation of the elastic body. The structural member (30) supports the gas-permeable membrane (10) and the ventilation valve (20). In an attached state where the ventilation component (1) is attached to the housing (2), ventilation between an inside of the housing (2) and an outside of the housing (2) is carried out via the gas-permeable membrane (10), and the ventilation valve (20) is opened to discharge a gas inside the housing 2 to the outside of the housing 2 when a difference between a pressure inside the housing (2) and a pressure outside the housing (2) is equal to or higher than a predetermined value.Type: GrantFiled: October 17, 2019Date of Patent: December 27, 2022Assignee: NITTO DENKO CORPORATIONInventors: Yusuke Nakayama, Youzou Yano, Akira Miyagaki

Publication number: 20220120354Abstract: A ventilation component (1a) includes a valve body portion (10), a shaft portion (20), a ventilation path (15), and a gas-permeable membrane (30). The valve body portion (10) has an umbrella cloth shape. The shaft portion (20) extends in a normal direction of the valve body portion (10). The shaft portion (20) supports the valve body portion (10). The ventilation path (15) extends through the shaft portion (20) in the normal direction of the valve body portion (10). The gas-permeable membrane (30) closes the ventilation path (15) such that ventilation can occur. In a state where the ventilation component (1a) is fixed to a housing (50), the valve body portion (10) covers a peripheral opening (55) and an outer circumferential portion of the valve body portion (10) is in contact with an outer surface (52a) of the housing (50) such that a flow of gas passing through the peripheral opening (55) is blocked.Type: ApplicationFiled: January 24, 2020Publication date: April 21, 2022Inventors: Yusuke NAKAYAMA, Youzou YANO, Tomoyuki KASAGI, Akira MIYAGAKI
