Abstract
A vibrator with a variable moment uses a phase shifter (7) including at least two trains of flyweights each including at least two eccentric flyweights driven into rotation by two cogs which mesh with each other so as to rotate in the opposite direction relative to each other. Both trains of flyweights are coupled to each other through a remotely controllable phase shifter (7) including a first tubular drive shaft (9) interdependent in rotation at one of the its ends, with a first cog (P4) and a second central drive shaft (6) which engages into the first tubular drive shaft (9) and which is interdependent in rotation with a second cog (P3) located opposite to the first cog (P4). A tubular transmission part (8) interdependent in rotation with the first tubular drive shaft (9) ensures a diversion of the stresses exerted at the cogs (P3, P4) thereby relieving the phase shifter.
