Abstract

Valve of distribution of fluid substances, for containers conditioned under pressure, comprising a cup or cup, (14) for fixing in the mouth of the container; an annular elastic joint (1) forming a valve seat sealingly inserted in the axial opening (15) of the cup (14), and a tubular cylindrical rod with a blind end (4) of distribution control forming an inserted valve, virtually sealed in the axial passage (6) of the joint (1) and compressing said joint (1) between a widening (16) of its blind end and an external projection (5) of its middle area, whose tubular rod (4) ) has a radial communication (12) between its blind axial conduit (13) and the interior (11) of the joint (1) facing the widening (16) of said blind end, whose valve is characterized in that the seal (1) presents at its end located outside such a container, a first internal annular projection (2) that fits into it an annular groove (3) made in the external wall of the stem (4) below the projection (5); the axial channel (6) of the joint (1) extends from this first projection (2) in an intermediate cylindrical area (7) with internal diameter somewhat lower than the external diameter of the rod (4) ending in a second peripheral projection (8) with an inner diameter smaller than the external diameter of the rod (4) that extends into a lipped annular internal edge (9), inclined toward the axis in the direction of the end (10) of the joint (1) located inside the container and forming a projection inside a cylindrical terminal widening (11), in sealed support against the outer wall of the rod (4) of the joint (1), above the radial communication (12) of the blind axial conduit (13) ; the intermediate cylindrical part (7) of the joint (1) is surrounded by a peripheral channel (24) spaced from the two projections (2), (8).
