Abstract
A filling valve for an aerosol container or the like has an endless channel surrounding a predetermined axis and having a transverse wall, an inner rim projecting from an inner region of this transverse wall and an outer rim projecting from an outer region of the transverse wall to an extent greater than the inner rim, this transverse wall being formed with at least one opening passing therethrough. A mounting cup has a central wall portion extending transversely with respect to the above axis and engaging the outer rim at an edge thereof distant from the transverse wall of the channel and extending inwardly from the outer rim toward the above axis. This central wall portion of the mounting cup is formed with a central opening through which the above axis extends, and the central wall portion of the mounting cup has an inner peripheral edge defining the central opening and situated closer to the above axis than the inner rim. In a gap which is defined between the inner rim and the central wall there is a resilient deformable, compressible seal member compressed between the inner rim and the central wall portion of the mounting cup, the arrangement being such that when the fluid under pressure is directed through the central opening of the transverse wall portion of the mounting cup the seal member will deflect at its outer periphery into the above channel so that the fluid under pressure will flow through the opening of the transverse wall thereof into a container.
