DISTRIBUTING CHAMBER Russian patent published in 2014 - IPC F28F9/00 

FIELD: machine building.

SUBSTANCE: distributing chamber (5) is externally limited by a casing (3), a bottom (2) and a grid (6) and provides for the interconnection of a central supply pipe (8) and a lateral outlet channel (1) via a gap between the bottom (2) and the end face part of the central supply pipe (8). The lateral outlet channel (1) is formed by the casing (3) and the central supply pipe (8). The grid (6) is installed in the lateral outlet channel (1) and its porosity factor falls in the range from 0.3 to 0.8. Ratios of the distributing chamber (5) dimensions correspond to the conditions considering the interrelations of the height of the distributing chamber (5) and the inner diameter of the central supply pipe (8); height of the inlet to the distributing chamber (5) and the inner diameter of the central supply pipe (8); height of the distributing chamber (5), height of the inlet to it and the inner diameter of the central supply pipe (8); height of the distributing chamber (5) and height of the inlet to it, radius of the lower casing (3) part, outer radius of the central supply pipe (8); distance from the bottom (2) to the step (7) on the casing (3) respectively with the height of the distributing chamber (5), and with the radius of the lower casing (3) part and height of the inlet to the distributing chamber (5); radius of the lower casing (3), inner diameter of the central supply pipe (8) and height of the inlet to the distributing chamber (5). Dimensions of the flow passage of the distributing chamber (5) are related with its hydrodynamic characteristics by a ratio considering the mass flow of working medium through the grid (4) hole, average mass flow of working medium through the grid, total pressure loss at the grid (4), density of working medium, average velocity of working medium in the central supply pipe (8), area of the cross-section of the working medium jet falling on the grid (4), radius of the upper casing (3) part, outer radius of the central supply pipe (8), reference radius of the grid (6) and three empirical coefficients.

EFFECT: expanded functionality at forming hydrodynamic irregularity at the distributing chamber outlet and simplified design.
