Abstract

Sealing plug with loading valve, characterized essentially by being formed by a discoidal head whose upper wall has an axial central perforation that is continued inferiorly, through a seat, in a tubular body carrying a series of lateral openings wherein a shutter or valve itself, which has the form of an inverted cup and is provided with longitudinal notches cut to bevel in the side wall of said valve and prolonged in respective notches made in the body, is mounted sliding inside said body. Bottom wall of such valve, whose last wall offers superior perpendicular lugs, circularly aligned and which are combined, in the manner of guides, with the aforementioned axial perforation of the upper wall of the discoidal head, coming arranged inside the body tabular guide a helical spring that rests against a ring or pin attached to the mouth lower of said body, whose spring tends to keep applied to the valve against the seat and allows that, by virtue of a pressure exerted by part of the pouring spout of the corresponding hose or equivalent on the ends of the lugs of the valve, it descends along the tubular body and are left facing the lateral openings of the latter the spaces left between the aforementioned lugs, and to the effect also that the notches of the valve are placed against the internal face of the body itself, all this at so that through the resulting steps the liquid passes to the corresponding deposit.
