Abstract
Abstract Relief arrangement for a gas turbine installation with an endless flow path for the operating medium; a relief pipe being provided which leads from a position of high pressure in said flow path to a position of lower pressure in said flow path; said relief pipe comprising at least two jointly redundant regulating valves connected parallel to one another as regards said operating medium; the improvement that a quantity limiter connected in series with said regulating valves is incorporated into said relief pipe.
