Abstract

A nozzle for oil, characterized in that it is constituted by a first tubular piece fixed to the container, whose bore has at its free end a part of smaller diameter and, at a distance from it, in the part of the bore of larger diameter, a small cylinder axial integral, concentric with the bore of the piece, tubular and smaller in diameter than this, which is attached inferiorly to the wall of the bore through opposite radial parts that leave between them through holes, the nozzle also having a second mobile tubular piece in whose lower half it has a diameter equal to the diameter of the end bore portion of smaller diameter of the fixed tubular part and ending in a thickened annular part of outer diameter equal to the larger bore diameter thereof and of less than the distance between the front free end of the inner cylinder and the beginning of the smaller diameter bore part of the fixed tubular part, also having said second moving part has a bore of small diameter that widens in the part of the thickened end thereof in a cylindrical part of diameter and length corresponding to those of the axial cylinder of the fixed part, the movable piece being inserted in the fixed piece of so that its thickened part can slide snugly in the larger diameter bore part of the fixed part while the axial cylinder thereof slides tightly the arrangement that when the movable part is introduced it completely seals the passage area between the inner cylinder and the surface of the bore of the fixed part and when it moves outward said area is free, going forward through the bore of the moving part that tapers towards the other end thereof, the output of the moving part being limited in turn. Thickened that makes butt against the beginning of the part of bore of smaller diameter of the fixed piece. (Machine-translation by Google Translate, not legally binding)
