Abstract
In a pneumatic or hydraulic pressure system a secondary tube, branch of the primary one, may have to be fed, at a certain ration, from the main flow, therefore the impulse transformer is incorporated. It consists of a piston driven at the rythem of the main flow, having step by step a control piston which, after a certain fixed number of movements opens and closes perically the secondary pipe. Preferably, the secondary pipe may be fully open or closed at the end of a single stroke of the control piston.
