Latest Patents

Norell's latest patents include the "Compact Variable Pitch Fan" and the "Control System for Variable Pitch Fan." The Compact Variable Pitch Fan features a hydraulic pitch change mechanism, where a pitch change piston is constrained to follow reciprocating motion under hydraulic control within a peripheral hub from which fan blades extend outward. This design incorporates separated guiding and seal surfaces, along with a pitch sensor on the hydraulic line leading to the fan. The Control System for Variable Pitch Fan utilizes pulsed pressure to achieve pitch control. It allows for incremental variation of pitch towards or away from full pitch through the pulsed application of fluid to a piston. This innovative system also includes reverse pitch functionality to clear debris from the fan, with valves controlling the fluid flow to the piston.
