摘要：There is described a1 variable pitch propeller comprising at least one blade

pivoted rotatably to a cylindrical propeller casing (3), a drive shaft, coupled to a

propulsor and positioned coaxially inside the propeller casing, a kinematic mechanism

coupled to the drive shaft, or to the propeller casing, and to said blade, for adjusting the

rotary motion of the blade or blades about its axis of pivoting to the propeller casing,

and means for coupling in rotation the drive shaft to the propeller casing. The propeller

is configured to provide at least one non-null angular range of relative rotation of the

blade or blades about its axis of pivoting, with respect to the propeller casing, or vice

versa. The means for coupling in rotation the drive shaft to the cylindrical propeller

casing comprise at least one elastic element (8) interposed between the drive shaft and

the cylindrical casing preferably acting at least when the propulsor drives in rotation the

drive shaft according to at least one direction of rotation. The propeller also comprises

at least one intermediate element (11) interposed between the drive shaft and the

cylindrical propeller casing, provided with a first (20) and a second (21) contact surface

with the drive shaft that are mutually spaced apart by an angular space for rotation of

the drive shaft with respect to the intermediate element.
