Title:
流量装置及び該流量装置を使用する方法及びシステム
Document Type and Number:
Japanese Patent JP5925561
Kind Code:
B2
Abstract:
A flow device (50) adapted to operate as a restrictor as well as provide a pressure relief capability in the event of an over-pressurization event within a fluid system containing the device (50). The flow device (50) includes an expandable orifice (64) that has an outer perimeter (62), a plurality of cantilevered tabs (58) surrounded by the outer perimeter (62), and an opening (54) surrounded and defined by the tabs (58). The tabs (58) project from the outer perimeter (62) toward the opening (54), which restricts flow of the bleed air through the expandable orifice (64) at a pressure below a predetermined pressure level, but then expands to relieve an over-pressure condition of the bleed air at a pressure above the predetermined pressure level as a result of the cantilevered tabs (58) being deflected by the over-pressure condition. The device (50) is adaptable for use in aircraft applications, including the regulation of bleed air used in anti-icing/de-icing systems.
