Abstract

The present invention concerns an elastic device controlling the rotation speed of the oscillating jib of an irrigator, in which elastic reaction of right rotation is different from that of left rotation, each reaction being caused by a specific spring, said springs being tarred singularly. Both springs are contained inside the central hollow hub of said oscillating jib. Both springs are tarred differently in order to obtain a different oscillation frequency of said jib during the return motion of the rotation of the jet, said motion being faster than working motion.
