Passive servo filter for pneumatic valve with transverse actuator

摘要: A bleed assembly includes a valve disposed across duct. The housing (20), shaft (26) connecting an actuator (24) to flow control member (66), and servo tube (56). linear (38) perpendicular centerline, so that motion of the is transverse centerline. (66) in main fluid passage (28), rotatable between fully closed position defined by leading (68) trailing edges (70) abutting one or more walls, open edge at upstream side (34A) downstream (34B) (28). first portion (82) (56) extends into (28) from distance P1 position, angular A1 least 10° TDC position.
