A divisible housing of a fluid machine for a transmission to be received in the divisible housing is provided. The transmission provided for receiving in the divisible housing includes a large wheel and at least two pinion shafts which are in engagement with the large wheel. The divisible housing includes a first housing element and a second housing element which is connected to the first housing element via a parting joint. The at least two pinion shafts may be received in the parting joint. The parting joint includes a parting joint step, the at least two pinion shafts being receivable in the parting joint on both sides of the parting joint step.

A gas system has a first compressor stage for compressing a process gas. The first compressor stage includes an intake side and a pressure side. A seal gas is provided outside the first compressor stage in order to prevent process gas from issuing from leaks in the first compressor stage, having at least one second line for returning a gas mixture issuing from the gas system, this mixture including at least of process gas and seal gas. The at least one second line is configured for returning the issuing gas mixture to the intake side of the first compressor stage and/or to a location in the gas system upstream of the first compressor stage.

A nose dome for a turbomachine rotor is provided. The turbomachine rotor has an impeller which is arranged in an overhung fashion with respect to a bearing point of the turbomachine rotor. The nose dome can be connected axially to the impeller in order to guide an axial inflow and/or outflow of the impeller, and includes a coupling device. The impeller and the nose dome can be mechanically coupled radially with the coupling device, such that the vibration behavior of the turbomachine rotor may be influenced. The turbomachine with the turbomachine rotor including the nose dome is also provided. The impeller and nose dome are coupled radially using the coupling device, such that the vibration of the turbomachine rotor is damped.
