摘要

Improvements introduced in the aerographic pistols, consisting of the incorporation in a suitable point of the pistol body, of a rotary actuator piston in a housing provided for that purpose, and provided with a leakage seal of the circuit box, which entails its internal end is a joint that in the actuation of the piston determines the sealing of vertical ducts and the regulated passage of the air through the circuit box, to the collector slot of the nozzle from which it passes to the chamber in which produces the depression, so that the path of the expressed plunger determines the air flow and consequently the necessary pressure, with the advantage that with the path of the needle only the passage of product is regulated and thus the proportionality can be achieved desired in terms of the product-air equation.
