Device for air mass flow control

摘要

A device for air mass flow control in a gas turbine engine includes at least one inlet duct 1, which can issue into an air duct 2, a counter-pressure duct 3, and a double-action shut-off element, which is connected between the counter-pressure duct 3 and the inlet duct 1 and is responsive to pressure differences between the two ducts to control air flow in the air duct 2.
