Abstract:
A curved blower conduit vented for pressure relief, having an entrance end connectable to an outlet portal of a blower and an exit end connectable to an inlet portal of a cargo container, for carrying the blower's exhaust air stream to the cargo container, comprising in combination:a curved sector conduit extending between and joining said entrance end and said exit end,attachment means mounted on said sector conduit near said ends for securing said connections,an outer peripheral portion of said sector conduit having a first radius of curvature,an inner peripheral portion of said sector conduit having a second radius of curvature substantially smaller than said first radius of curvature, andvent means connecting the interior of said sector conduit, at a point of said inner peripheral portion intermediate between said entrance end and said exit end, to the external atmosphere,whereby the blower's exhaust air stream is concentrated near the outer peripheral portion, relieving pressure in said cargo container by directing any return flow stream along the inner peripheral portion and out through said vent means.
