Abstract
A variable-pitch propeller has a pair of fixed pistons in the hub thereof, and a cylinder hydraulically movable on these fixed pistons and connected to the blades to vary the pitch of the blades. One of the fixed pistons is hollow and contains an auxiliary piston movable under the influence of a separate hydraulic system into engagement with the cylinder so that if the first hydraulic system fails, the auxiliary system can at least get the ship to port. The auxiliary hydraulic system can include a separate passage through the propeller shaft, or a branch from the lubricant passage through the propeller shaft.
