JET APPARATUS Russian patent published in 2025 - IPC F04F5/04 F04F5/44 

FIELD: mechanical engineering.

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 the range of operating parameters of the flow at the nozzle outlet, increase in the number of working chambers and, accordingly, the number of consumers. Said problem is solved by the fact that the jet device comprises at least two sources of the working medium, working chambers, a nozzle with inlet channels and outlet channels, nozzles arranged in the cavity between the inlet and outlet channels of the diaphragm, installed on the rods, with the possibility of reciprocating movement of each diaphragm relative to the outlet channel of the nozzle, wherein each pair of diaphragm and rod has cross section in form of circle or polygon, and the nozzle outlet channel, respectively, has a circular or polygonal cross-section to allow the diaphragm and rod to move through the nozzle outlet channel, to completely overlap one or more nozzle outlet channels and to control the flow of the working medium into one of the working chambers or simultaneously into several working chambers, wherein working medium sources are connected via shutoff-control devices to nozzle inlet channels to allow simultaneous supply of working medium from several working medium sources to nozzle inlet channels or to sequentially in time connect working medium sources to one nozzle inlet channel.

EFFECT: providing controlled redistribution of flow energy in several directions from the nozzle due to optimal arrangement of nozzle outlet channels and, accordingly, flexible adjustment of hydraulic connection between sources of working medium, inlet channels of nozzle and outlet channels of nozzle, including versions with complete disconnection of separate outlet channel of nozzle.
