METHOD FOR MANUFACTURING DEVICE FOR REDUCING FLUID PRESSURE Russian patent published in 2022 - IPC F16K47/08 B22F3/00 B33Y10/00 

FIELD: fluid control devices.

SUBSTANCE: invention relates to devices for reducing fluid pressure. A device for reducing fluid pressure for use in a device for fluid flow control contains a single case containing an inner wall and an outer wall radially spaced outward from the inner wall. The single case passes along the longitudinal axis and has a length defined from the upper end of the single case to the lower end of the single case opposite the upper end. The device also contains a set of flow channels defined between the inner wall and the outer wall of the single case. Each of flow channels contains an inlet made in the inner wall, an outlet made in the outer wall, and an intermediate section passing between the inlet and the outlet. At least part of the intermediate section passes in the direction that is essentially parallel to the longitudinal axis, for at least the main length of the single case.

EFFECT: providing a reduction in fluid pressure.
