FLIGHT CRAFT WITH FLUID SYSTEMS WHICH INCORPORATE BUTTERFLY VALVES, AND BUTTERFLY VALVE METHODS AND APPARATUS

摘要

The invention relates to a method for facilitating control of a butterfly valve, to butterfly valves (40, 180) for use with this method as well as a hydraulic system (242) incorporating such valves . All three use or incorporate a structure valves butterflies which ensures a relative translational movement (246) between the valve plate (42, 182, 248) and a pivot axis (232), to modify the dynamic torque of the hydraulic fluid acting on the valve plate.
