Description
The present invention relates to a rapid-acting flow modulation valve designed to modulate a fluid flow in response to an externally supplied control signal commanding at an extremely high rate. The flow modulation valve incorporates pressure balanced throttling components, a fast-acting coil actuator, low hysteresis movement, and an energy-dense magnetic geometry in order to produce high frequency flow modulation in response to input drive signals. The flow modulation valve may be utilized for applications requiring readily amenable retrofitting, small diameter working fluid lines, high operational frequency, strict controllability, and low production and maintenance cost, among other advantages. An embodiment of the flow modulation valve is designed to operate in high temperature, high line pressure environments where rapid flow modulation is advantageous or required, such as gas turbine active combustion control systems, variable valve timing engines, or other applications requiring high speed throttling operations.
