    • A valve device for pressurised-gas packages is disclosed, which has a valve body consisting of a hollow stem and a stem body connected thereto, a valve housing in which the stem body is accommodated with the stem protruding from the valve housing and which opens into the pressurised-gas package, a spring on which the stem body is arranged and which is supported in the valve housing in the region of the opening towards the pressurised-gas package, and a valve plate which closes the pressurised-gas package and contains an opening through which the hollow stem extends. The valve housing is sealed off relative to the valve plate by a seal which surrounds the stem. The stem contains a lateral bore which is closed by the seal when the spring is unstressed or almost unstressed. In this case, there is provided with spacing from the one seal a further seal which surrounds the stem and terminates with the valve housing so that an essentially gas-tight space is formed between the two seals, which space communicates with the region of the pressurised-gas package containing propellents via an opening provided between the seals in the valve housing.
