This pump and flow control system employs variable pre-swirl combined with thermal control to provide efficient modulated thermal management. Applied to cooling systems, the controllable variable output provides fuel savings and performance gains.

 

Technology Background

The use of variable inlet guide vanes to provide pre-swirl has long been recognized as the most efficient method of achieving variable output for turbo-machinery applications including Kaplan and Francis turbines, and variable geometry turbochargers.

Conventional thermostats employed in today's automotive engine cooling systems throttle flow through the radiator and bypass circuits, but do not vary the pump's capacity.
