<p>Pressurization system to be adapted to a hydraulic system, by placing a by-pass adapted to the system, a water pump and a retention valve with a conical seat. In the by-pass, a magnetic actuator formed by a permanent magnet placed inside a pipe, with its movement limited by non-magnetic pins and by a reed-relay ampoule positioned externally to the area of movement of the permanent magnet is adapted. As the magnet is dragged along by the flow of liquid, the reed-relay is put into action, which puts an electro-magnetic contact into action, which, in its turn, switches on the water pump and so maintains the system adequately pressurized.</p> |
