JET APPARATUS Russian patent published in 2024 - IPC F04F5/44 

FIELD: jet equipment.

SUBSTANCE: invention relates to the field of jet equipment, including jet pumps and compressors, jet control systems and jet propulsors for dynamic positioning systems with thrust vector control. Technical problem to be solved by the present invention is the expansion of variability of working parameters of the flow at the outlet of the nozzle and at the outlet of the working chambers. Said problem is solved by the fact that the jet device comprises at least two working chambers, a nozzle with inlet and outlet channels and a diaphragm arranged in the nozzle cavity between the inlet and outlet channels of the nozzle and mounted on the end of the hinged rod, with possibility of diaphragm reciprocating or angular movement relative to nozzle outlet channel, wherein diaphragm has cross section in form of circle or polygon, and the nozzle outlet channel has a round or polygonal cross section ensuring movement of the diaphragm through the nozzle outlet channel, complete blocking of the nozzle outlet channel or one of the working chambers and controlled direction of working medium flow into one of working chambers or simultaneously into several working chambers.

EFFECT: providing controlled redistribution of flow energy in separate working chambers due to flexible adjustment of hydraulic connection between nozzle inlet channel and working chambers and, as a result, providing control of parameters of "momentum" of flows in the cross section at the outlet of the nozzle and separate working chambers, including complete shutdown of the nozzle, one or more working chambers, which is essential in emergency situations, in particular in case of sudden disconnection of energy consumers.
