LINEAR ACTUATOR FOR A BLEED VALVE |
摘要 |
<p>In a control system for a turbine engine having a variable geometry air compressor, a valve arrangement responsive to a first operational pressure differential created between a discharge fluid pressure produced by the air compressor and an environmental fluid pressure for controlling the communication of a first fluid pressure to an actuator assembly which responds to a second operational pressure differential created across a piston between the first fluid pressure and a second fluid pressure produced through a modification of the discharge fluid pressure. The second fluid pressure being developed by compressor discharge fluid pressure flowing from a blind bore in a shaft through a variable opening to one side if the piston while at the same time fluid pressure flows through a restriction to the surrounding environment. The resulting second pressure differential acts on the piston to provide the shaft with a force which is communicated through linkage to linearly change the shape of a variable area geometry device of the air compressor.</p> |
