ABSTRACT:
A combustion chamber of a gas turbine engine has a combustion cowl and transition piece with at least one air gap provided therebetween. The air gap opens into an intermediate chamber having two throttles which are arranged oppositely with respect to one another. The two throttles are provided in a cooling jacket which is divided into two portions by the throttles. The air gap permits the combustion cowl and transition piece to expand freely with respect to each other. The two throttles are arranged so that fuel gas leaving the combustion chamber provides an injector effect to expedite the flow of a coolant such as air through the air gap.
