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.

Dependent claims

A valve arrangement for a pressurised fluid container, comprising

a valve disc (10) which may be sealingly connected to a fluid container,
a valve body (20) made of plastics which may be secured in an opening of the valve disc (10),
a valve piston (30) made of plastics which is guided in a through-channel of the valve body (20) and cooperates with a sealing surface (26) of the valve body and
a spring arrangement (40) cooperating with the valve body (20), which presses the valve piston (30) against the sealing surface (26) of the valve body (20),
characterised in that the valve body (20) comprises a neck (23) defining the through-channel and at least one collar segment (24), an annular groove (21) being formed between the neck (23) and the at least one collar segment (24), and into the annular groove (21) a press ring (50) is introduced, of which the thickness in the radial direction is such that the at least one collar segment (24) is pressed in a spread-apart manner against the opening of the valve disc (10).
