JET APPARATUS Russian patent published in 2023 - IPC F04F5/44 

FIELD: jet technology.

SUBSTANCE: invention relates to the field of jet technology, including jet pumps and compressors, jet control systems and jet propulsion systems for dynamic positioning systems. In particular, the claimed technical solution can be used in the oil and gas industry to improve the efficiency of technologies in the production and processing of hydrocarbons, including in the development of offshore fields. The jet apparatus is characterized by the fact that it contains at least two working chambers, a nozzle with inlet and outlet channels and a diaphragm located between the inlet and outlet channels of the nozzle, on which a rod is mounted with the possibility of reciprocating or angular movement of the diaphragm relative to the outlet channel of the nozzle and with providing an adjustable direction of the flow of the working medium into one of the working chambers.

EFFECT: providing a controlled redistribution of flow energy in individual working chambers with the provision of regulation of the parameters of the "momentum" of the flows in the cross section at the outlet of the nozzle and individual working chambers and the possibility of completely shutting down one or more working chambers in emergency situations, in particular in case of sudden disconnection of energy consumers.
