Abstract
The present application provides a control valve actuator cooling system for providing a flow of cooling air to a control valve actuator. The control valve actuator cooling system may include a pressurized air source with the flow of cooling air, an air timing valve system, and a cooling air discharge port positioned about the control valve actuator such that the air timing valve system provides the flow of cooling air to the control valve actuator on an intermittent basis.

A control valve actuator cooling system for providing a flow of cooling air to a control valve actuator, comprising:
- a pressurized air source with the flow of cooling air;
- an air timing valve system;
- and
- a cooling air discharge port positioned about the control valve actuator such that the air timing valve system provides the flow of cooling air to the control valve actuator on an intermittent basis.
A method of cooling an actuator used with a control valve in a gas turbine engine, comprising:
- providing a source of pressurized air;
- flowing the pressurized air to an air timing valve system;
- building pressure within the air timing valve system;
- opening the air timing valve system at a predetermined pressure;
- and
- flowing the pressurized air to the actuator for a predetermined length of time to cool the actuator.
A gas turbine engine, comprising:
- a compressor;
- a turbine;
- and
- an air extraction system extending from the compressor to the turbine;
- the air extraction system comprising one or more control valve actuators positioned about the turbine;
- and
- a control valve actuator cooling system for providing an intermittent flow of cooling air to the one or more control valve actuators.
