Abstract

Automatic suction cup, essentially characterized by being constituted from a cylindrical, hollow body, devoid of both bases, of which the lower one receives the coupling of a short conical section that is then continued in another cylindrical of smaller diameter, having been foreseen in this section cylindrical lower the external adaptation of a conventional flange to, through it, link the assembly to the optimal point of the pipe in question, with the particularity this cylindrical body of presenting a series of fins linked radially and longitudinally to its internal lateral surface, as well as other fins, in the same arrangement, in correspondence with the internal surface of the conical section, these latter fins coming to constitute the points of support and solidarity of a conical deflector whose cusp is oriented centrally towards the lower mouth of the assembly, and its diameter determines an annular passage with respect to the wall internal of the cylindrical body, said cylindrical body furthermore being characterized by having in its upper mouth a flange intimately linked to its inner wall and flush with the edge of such an embouchure, which flange presents a sharp chamfering at the edge of its internal diameter related to the surface facing the inside of the cylindrical body, as well as the application of an annular sealing gasket joined to the flange surface opposite to that which incorporates said chamfering to orient such a joint to the lateral surface of a new independent flange that is intended by means of threaded studs, to be connected to the flange of the cylindrical body, this flange having the independent fitting of a gasket of, for example, neoprene, with orientation towards the inside of the cylindrical body, as well as a perforated bell which, fixed to the same through the aforementioned asparagus, is stabilized on the eye of such a bridle; having also provided, inside said cylindrical body, the housing of a second body, also cylindrical and hollow, which is installed with relative clearance in the space defined by the aforementioned fins of the external cylindrical body, which second body, in the rest state of the suction cup, rests on the support that supposes the presence of the conical baffle, its upper base remaining at some distance from the upper flanges.
