pitch settings in the event of overspeed conditions the fuel governor 18 controls the amount of fuel to a turbine engine not shown by means of a fuel control lever 19 the governor assembly 12 includes a beta valve 20 also connected to apply hydraulic fluid to the propeller 10 through the internal passageways in the governor assembly 12 the beta valve 20 may be initially positioned by a push pull control rod 22 operating through a floating reversing lever 23 the opposite end of the floating reversing lever 23 is connected to a slider brush or block 24 which runs in a groove in a beta position feedback collar 25 carried on the propeller 10 the pilot 39 s power levers not shown are connected to the push pull control rod 22 through the propeller throttle mixer cam 30 of this invention and cam follower lever 60 the propeller 10 has a hub 35 in which a plurality of propeller blades 36 are mounted typically three or more the position of the propeller blades is controlled by a fluid motor piston 37 opposed by the spring 38 and conventional counterweights 39 applying hydraulic fluid to the propeller causes the blades 36 to move to a lower pitch position and into reverse.
