Abstract (en)
[origin: EP1878655A2] The device has a pressure relief valve (5) mounted on a valve carrier (3). A compensation chamber is delimited by a movable support (31) for a compression spring (4), and a manually actionable control button (9) is rotative around an axis of a tubular body (101) that includes an opening (2). A movable cover plate (20) has a wall concentric to the body, and is integrated to the button. The button cooperates with the opening and the plate for adjusting the opening force of the valve and outlet gas flow simultaneously.
