Improved pneumatic timer, essentially characterized in that it is constituted by a bellows whose air intake is controlled by a circular channel of little section practiced in a discoidal body linked to the regulating knob, said channel being faced with a hole made in a washer fixed hole communicates with the air inlet to the inside of the bellows, while the air intake mouth is defined by a side hole made in the fixed washer, opening said hole in a circular groove that communicates with a recess made in the discoidal body from which the circular channel is born, with the particularity that the position of the discoidal body with respect to the fixed washer determines the section of the circular channel that the air must travel before reaching the inside of the bellows, a valve having been provided inside the bellows for the expulsion of air, whose stem emerges to the outside determined a front for the activation of the timer.
