Abstract
Improved retention valve, characterized by being integrated by two metallic pieces of non-oxidizable material, permanently gathered by agrafting, between which a membrane of a very flexible material is disposed which, according to the sense in which it is requested by an increase or a decrease of pressure, opens or closes by seat the inlet conduit and, therefore, allows or prevents the circulation of the fluid through its tubular assembly.
