Abstract

Automatic spray gun, of the type comprising a hose connected to a pressurized water line in which a venturi tube has been fitted with a dosing device that can suck active product from a container through a non-return valve, characterized essentially by the fact of comprising a handle in the upper front part of which comprises the intake, maneuver and ejection chamber; because in the upper part of the handle and immediately to said chamber a long trigger is articulated by means of a pin, which, in turn, comprises another pin which determines the axis of rotation of a short trigger and traverses the rear end of the trigger. A stem projecting from the rear of the chamber, because said chamber, of cylindrical configuration, has an expulsion nozzle in its front part and means of coupling to the hose in the middle zone of its lower part and is crossed by the stem cited, the path of which coincides with the axis of symmetry of the camera, whose rod has near its front end a fixed head carrying a closure that is applied against an internal surrounding projection of the camera, which acts as an element of closing, and between said head and the rear partition of the chamber there is a coil recovery spring coaxial to the rod; because the short trigger is slightly eccentric with respect to the pin that is its own, one spring tends to keep it separate from the other trigger and its innermost end is likely to trip on a step practiced at the edge of the grip that is closest.
