Abstract

A valve device 1 for admitting air to a pipe such as a stack pipe 2 in a domestic toilet system is shown. The valve device 1 comprises a body 3 adapted to be mounted on the pipe 2 at an open end 4 of the body 3 which has a closed end provided by an end closure or a cap 5 with a depending skirt 6 which reaches to the lower (as viewed) limit of an opening 7 in the body 3 to atmospheric air. The body 3 has an internal wall 8 which extends part way across the body 3 internally, the internal wall 8 having a through orifice or hole 9 and being part cylindrical. An upwardly extending part 10 of the wall 8 and a part 11 terminate in a nose 12 which supports the underside of a valve member 13.
