Abstract

In an hydraulically operated variable pitch propeller 1 having a piston and cylinder arrangement 7, the piston 11 is connected to a pull-rod acted upon by an auxiliary hydraulic motor, having a piston 25, through a lost-motion connection 39. If the hydraulic system fails, pressure fluid is admitted to the auxiliary motor via connection 29 to pull the blades into the " fullahead " position. The pressure pipes for the piston and cylinder 7 may be used as the pullrod.
