<p>The valve (10) has a fixed housing part (12) including a radial inner section (18) and a radial outer section (19). A movable valve body (13) is positioned between the sections, such that a gas stream (22) flows between the inner section and the body, and another gas stream (23) flows between the outer section and the body, to a gas outlet chamber (16) in an open position of the valve. The body is movable by servo pressure opposite to gas outlet pressure and opposite to or together with a spring force of a spring element (21) in a direction of a maximum opening position.</p> |
