Abstract
A controllable Pitot device uses a Pitot nozzle supported by a Pitot nozzle holder for pumping fluid flowing in a first direction or in a second direction flowing opposite the first direction. The Pitot nozzle has one ingestion inlet pivotable to ingest fluid from either direction. Ingested fluid impinges on an obstacle interior to the Pitot nozzle which is disposed opposite the ingestion inlet to create a zone of fluid at stagnation pressure. Stagnation pressure pumps fluid via the interior of the Pitot nozzle through one of two openings for discharging pumped fluid out of a discharge outlet supported by the nozzle holder, to the exterior of the Pitot device. The nozzle holder can be a support structure or an embedded support operative with a rotating fluid machine.
