Valve arrangement for discharging a fluid medium maintained under pressure in a container

摘要

A valve arrangement (1) for use in a container for discharging a fluid medium maintained under pressure in the container, particularly a cylindrical container. The valve arrangement includes a pot-shaped valve disk (2) to be secured in an open side of the container. The valve disk (2) has a coupling device (4) for connection to a container adapter of a discharging device. The valve disk (2) has a discharging valve (11) including a valve piston (12) and a restoring device (15). The pot-shaped disk valve (2) is formed of a plastics material with a plastically deformable and especially clinchable cylindrical pot wall (3). The coupling device (4) is an integral part of the valve disk (2) and is joined by thin cross sections (5) with the pot wall (3).
