Abstract
A valve and a heat exchanger apparatus for a gas turbine engine include a valve body having a valve seat and an actuation component including a plate formed from a set of metal layers and responsive to a change in at least one of a thermal condition and a pressure exerted thereon such that the plate moves and the valve moves between an opened and a closed position where a portion of the plate engages with the valve seat.
Claims21
A valve, comprising:
- a valve body having a valve seat;
- and
- an actuation component including a plate formed from a set of metal layers responsive to a change in at least one of a thermal condition or a pressure exerted thereon such that the valve moves between an opened and a closed position where the plate engages with the valve seat.
A heat exchanger apparatus for use in an oil cooling system of an aircraft engine comprising:
- an air-cooled oil cooler disposed in a bypass fan duct of the aircraft engine;
- and
- a valve, in fluid communication with the air-cooled oil cooler, the valve comprising:
- a valve body having a valve seat;
- and
- an actuation component including a plate formed from a set of metal layers and responsive to a change in at least one of a thermal condition and a pressure exerted thereon such that the plate moves and the valve moves between an opened and a closed position where the plate engages with the valve seat.

A turbine engine, comprising:
- a core engine;
- and
- a heat exchanger apparatus comprising:
- an air-cooled oil cooler disposed in a bypass fan duct of the turbine engine;
- and
- a bypass valve, in fluid communication with the air-cooled oil cooler, the bypass valve comprising:
- a valve body having a valve seat;
- and
- an actuation component including a plate formed from a set of metal layers and responsive to a change in at least one of a thermal condition or a pressure exerted thereon such that the plate moves and the valve moves between an opened and a closed position where the plate engages with the valve seat;
- and
- wherein the valve is configured to provide a bypass for at least a portion of a hot engine oil directed toward the air-cooled oil cooler and direct it back to the engine core prior to reaching the air-cooled oil cooler.
