Abstract

Volume regulating device of the type that uses a pressure difference control membrane element, which influences a mobile element, which regulates the air flow in a channel, the mobile element being able to rotate around an axis and the discharge being rotating element for example by means of a counterweight that can be adjusted in advance, characterized in that the axis of rotation of the rotating element is outside the pivot point, because at least one arm forms the connection between the pivot point and the mobile element, and because the arm supports a sliding load weight.
