A diffuser of a thermal energy machine, in particular of a gas turbine, has a diffuser inlet, a diffuser outlet, and a plurality of air-guiding elements, wherein an air mass flow enters the diffuser through the diffuser inlet, and wherein the air mass flow that has entered the diffuser exits the diffuser through the diffuser outlet and flows off as a plurality of partial air mass flows by the air-guiding elements. At least two immediately adjacent air-guiding elements of the plurality of air-guiding elements are designed in such a way that the flow-off angles thereof with respect to the circumferential surface formed by the outlet opening of the diffuser outlet extending circumferentially in the circumferential direction differ from each other.

A closing assembly for closing the gap remaining between the first and last blade of a blade ring that is inserted into a peripheral groove of turbomachinery is provided. The assembly includes at least two parts each of which can be hooked onto projections that form an undercut in the peripheral groove and includes a securing element, which secures the parts from becoming detached from the peripheral groove. For closing the remaining gap, the securing element is mounted to rotate about its longitudinal axis between the two parts and has a key head and a web. The web can be positioned by rotation is such a way that to fit the parts in the peripheral groove. The parts can be displaced in relation to one another and to secure the parts from being detached from the groove. The web can be placed against at least one lateral face of one of the parts.

Closing assembly for a blade ring of turbomachinery

A closing assembly is provided. The closing assembly closes the gap remaining between the first blade and the last blade of a blade ring that is inserted in a peripheral groove of a turbo machinery, the assembly consisting of at least two lateral parts, at least one of which may be hooked onto a projection that forms an undercut in the peripheral groove and at least one securing element, which secures the parts from coming detached from the peripheral groove. To provide a particularly reliable closing assembly, the securing element is configured as a pin, joining the parts of the closing assembly in a non-positive fit.
