Abstract

Valve arrangement for a pressurized fluid container, consisting of a valve disc which may be sealingly connected to the fluid container, a valve body made of plastics which may be secured in an opening of the valve disc, a valve piston made of plastics which is guided in a through-channel of the valve body and cooperates with a sealing surface of the valve body and a spring arrangement cooperating with the valve body, which presses the valve piston against the sealing surface of the valve body, the valve body comprising a neck defining the through-channel and at least one collar segment, an annular groove being formed between the neck and the at least one collar segment, and into the annular groove a press ring being introduced, of which the thickness in the radial direction is such that the at least one collar segment is pressed in a spread-apart manner against the opening of the valve disc.
