Abstract

The device comprises in a body a pressure limiting stage, a second stage constituting a fluid check and retarding valve and piloting means between these two stages. The second stage comprises regulating means which are easily accessible from outside the body. The device is particularly compact and is of high interest, for example when it is incorporated in a self-contained cylinder structure.
