The present invention relates to a housing arrangement for a turbomachine, comprising a support element, which is configured to bear a shaft, and a housing, which is centered at the support element. The housing is composed of an inner housing and an outer housing fastened at the support element, the housings being connected to each other by at least one connecting strut. A press fit is provided between the support element and the inner housing, in order to center the inner housing at the support element.

Gas turbine combustor

A device operates a swirling device which controls the flow rate of combustion air of a burner for gas turbine engines. At the head end of a combustion chamber, a ring body which is arranged coaxially with respect to the fuel nozzle is to have swirling ducts whose cross-sections are controllable by duct walls of a ring which is axially displaceable on the ring body. The axial displacement of the ring is to take place by means of a control piston which is axially displaceable in a housing, is spring-loaded on one side, is also actuated by a valve-controlled pressure difference existing on the spring side between an ambient pressure and a primary air pressure, controls openings communicating with the valve and the head end of the combustion chamber, and is acted upon on piston surfaces, which are free with respect to the housing, on the one side, by a pressure of supplied primary air existing at the head end and, on the other side, by the chamber pressure existing at the burner.
