A combustion chamber comprises an outer wall and an inner wall spaced from the outer wall. The outer wall has at least one mounting aperture extending there-through and the inner wall has threaded studs extending there-from. The threaded studs extend through the mounting apertures in the outer wall. Cooperating nuts locate on the studs and washers are positioned between the outer wall and the cooperating nuts. Each washer has a rim and a bore. The washers have one or more passages extending there-through from the rim to the bore of the washer to provide a flow of coolant through the passages in the washers, the mounting apertures in the outer wall and around the threaded studs to cool the threaded studs to increase the working life of the inner wall. Other cooling arrangements for the threaded studs are disclosed.
A combustion chamber comprising an outer wall and an inner wall spaced from the outer wall, the outer wall having at least one mounting aperture extending there-through, the inner wall having at least one fastener extending there-from, the at least one fastener on the inner wall extending through a corresponding mounting aperture in the outer wall, a cooperating fastener locating on the at least one fastener extending through the corresponding mounting aperture and a washer positioned on the at least one fastener between the outer wall and the cooperating fastener, the washer having a first surface abutting an outer surface of the outer wall and a second surface abutting a surface of the cooperating fastener, the washer having a rim and a bore, the washer having at least one passage extending there-through from the rim to the bore and/or the washer having at least one groove extending from the rim towards the bore on the first surface and/or the washer having at least one groove extending from the bore towards the rim on the second surface and/or the surface of the cooperating fastener abutting the second surface of the washer having at least one groove extending towards the bore of the washer whereby a flow of coolant is provided to flow through the mounting aperture and around the at least one fastener.
A combustion chamber comprising an outer wall and an inner wall spaced from the outer wall, the outer wall having at least one mounting aperture extending there-through, the inner wall having at least one fastener extending there-from, the at least one fastener on the inner wall extending through a corresponding mounting aperture in the outer wall, a cooperating fastener locating on the at least one fastener extending through the corresponding mounting aperture and a washer positioned on the at least one fastener between the outer wall and the cooperating fastener, the washer having a first surface abutting an outer surface of the outer wall and a second surface abutting a surface of the cooperating fastener, the washer having a rim and a bore, the washer having at least one passage, the at least one passage being selected from the group consisting of at least one passage extending through the washer from the rim to the bore, at least one groove extending from the rim towards the bore on the first surface of the washer and at least one groove extending from the bore towards the rim on the second surface of the washer whereby a flow of coolant is provided to flow through the mounting aperture and around the at least one fastener.
A combustion chamber comprising an outer wall and an inner wall spaced from the outer wall, the outer wall having at least one mounting aperture extending there-through, the inner wall having at least one fastener extending there-from, the at least one fastener on the inner wall extending through a corresponding mounting aperture in the outer wall, a cooperating fastener locating on the at least one fastener extending through the corresponding mounting aperture and a washer positioned on the fastener between the outer wall and the cooperating fastener, the washer having a first surface abutting an outer surface of the outer wall and a second surface abutting a surface of the cooperating fastener, the washer having a rim and a bore, the surface of the cooperating fastener abutting the second surface of the washer having at least one groove extending towards the bore of the washer whereby a flow of coolant is provided to flow through the mounting aperture and around the at least one fastener.
