JET INSTALLATION Russian patent published in 2024 - IPC F04F5/02 F04F5/46 

FIELD: jet technology.

SUBSTANCE: invention relates to jet pumps and compressors, jet amplifiers with control systems and jet propulsors for dynamic positioning systems with thrust vector control, and can be used, in particular, in the oil and gas industry to improve the efficiency of production technologies and processing of hydrocarbons, including in the conditions of development of offshore fields with underwater placement of equipment. The jet installation contains sources of working and pumped medium, a jet apparatus equipped with a system of nozzles hydraulically connected in a parallel circuit and placed at the entrance to the working chamber to form an annular channel in which U-shaped pockets are placed with the formation of supply channels isolated from each other in them, in each of which one nozzle is installed and which hydraulically connect the working chamber with sources of the pumped medium through shut-off control devices, while the source of the working medium is connected to the inputs of the nozzles through a hydraulic distributor, and in the working chamber there are multidirectional output channels, each of which communicates with a separate supply channel, ensuring the supply of a mixture of working and pumped medium in the direction from the periphery to the centre of the working chamber.

EFFECT: ensuring a controlled redistribution of the flow energy over the area of the output channel in the working chamber with the ability to regulate the parameters of the flow momentum and the parameters of the velocity diagram in the cross section at the exit of the working chamber and with the simultaneous creation of conditions for controlling the thrust vector within the geometric hemisphere or in within a complete geometric sphere.
