Abstract

Improvements in the construction of variable pitch propeller fans, in particular for domestic use, of the type according to which the propeller blades are rotatably mounted on pivots substantially perpendicular to the axis of rotation of the fan by being entangling in bearings provided in the driving hub in rotation of the propeller, these pivots being integral with spurs, or the like, which are offset with respect to the axis of rotation of the pivots, said spurs being driven in translation parallel to the axis of rotation of the fan by means of a control piece which it positions them, which has an annular shape and slides with a certain play on the rotary drive shaft of the fan, characterized by consisting of two annular parts (14, 19) mounted around the shaft (3) of rotation of the rotating propeller freely in said annular pieces, these annular pieces being arranged and pressed between said control piece (11) of variation of the passage of the propeller and the fixed support frame (20) of the fan, said annular pieces forming at least one inclined ramp (18) and being capable of being sent in relative rotation around the axis x'x of rotation of the propeller by a control arm or similar (17) secured to at least one of said annular parts (14, 19).
