A method is disclosed which limits soiling of internal turbomachine parts from dirt originating with process gas. In between at least two successive faces in which the turbomachine is operated normally, and during which time only process gas is introduced into the inlet of the turbomachine, a cleaning phase is initiated. During this phase, a substance in a dense state is introduced at the inlet which is capable of dissolving the dirt on internal parts of the turbomachine. Process gas and the dirt dissolving substance are separated.

Method and device for controlling a turbo-machine so as to limit clogging of the turbo-machine internal parts with impurities derived from a process gas

A hydro-dynamic fluid-bearing assembly constituted by bearing members disposed around a rotary shaft with the interposition of a film of pressure fluid. At least one of the bearing members is subject when the shaft is stopped to the action of a resilient member generating a limited pre-loading strictly necessary for maintaining the assembly in its correct interrelationship, the said resilient means being subject during operation of the shaft to the action of pressure fluid bled from the film of fluid under pressure lying beneath the bearing member and such that the load on the bearing member increases with the pressure of the fluid film.
