发明名称 Bleed air apparatus for turbomachine
摘要 <p>The extractor consists of a pivoted shell (5) which fits into an aperture (9) in the turbine wall between positions of maximum and minimum projection according to the speed of the air flow. The shell has an air intake (7) which faces towards the air flow when it is open to the maximum, and turns away from it as the air flow increases or decreases from a given level. The shell is shaped as a toroid section with a geometrical axis (6) on which it pivots, and has one or more peripheral apertures (20,45). The forward end of the shell has a peak (36) to receive the air flow, and its pivot is loaded by a spring (35).</p>
