Abstract
Abstract In the openings at the side wall of an infeed or inflow channel there are inserted outlet or discharge elements having an oval cross-section which continuously tapers in the flow direction. The inlet-side portion of the outlet elements, protruding into the interior of the infeed channel, possesses an outwardly drawn or flexed end portion or section which terminates in spaced relation from the channel side wall and forms therewith a catch trough. Within this trough there is entrapped water which is deposited at the inner surface or wall of the infeed channel and which flows downwardly along the channel side wall. At the outlet side of each outlet or discharge element there is arranged a further catch trough which extends at the inner surface of the outlet side or opening along the circumference. This inwardly open catch trough is formed by an end portion or section of the outlet element which is flexed or bent back towards the inside. By means of this catch trough the water which has been separated at the inner surface of the outlet element is prevented from reaching the region of the outlet opening. The base portion of the outlet element is constructed as a collecting trough which returns the separated water back into the interior of the infeed channel. Without the need to provide the outlet element with water separation elements arranged in the flow cross-section, there is avoided the exit of large water droplets out of the outlet or discharge elements.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
251 words
An air distribution apparatus comprising: inflow channel means; outlet elements provided at least at one side of said inflow channel means and distributed over the length of said at least one side of said inflow channel means; each of said outlet elements having a base portion for receiving water which has been separated out of air flowing through said inflow channel means; each of said outlet elements having a free flow cross-section; each of said outflow elements having an outlet opening; each of said outflow elements being provided with a catch element extending along the circumference of its outlet opening and serving to prevent the efflux of water precipitated at an inner surface of said outflow element; each of said outflow elements containing a collecting trough formed by said base portion; said collecting trough descending towards the interior of said inflow channel means; said collecting trough serving for the withdrawal of water which has been removed at the related outlet element; each of said outlet elements has an inlet opening; a plurality of ribs arranged at least at the region of the inlet opening of the related outlet element; said ribs being arranged so as to protrude from the base portion of the related outlet element and being disposed in spaced relationship from one another and extending essentially in the lengthwise direction of the related outlet element; and said plurality of ribs extend within the interior of the inflow channel means and subdivide the collecting trough into individual return flow channels.
Claim 2
Dependent Claim
251 words
An air distribution apparatus comprising: inflow channel means; outlet elements provided at least at one side of said inflow channel means and distributed over the length of said at least one side of said inflow channel means; each of said outlet elements having a base portion for receiving water which has been separated out of air flowing through said inflow channel means; each of said outlet elements having a free flow cross-section; each of said outflow elements having an outlet opening; each of said outflow elements being provided with a catch element extending along the circumference of its outlet opening and serving to prevent the efflux of water precipitated at an inner surface of said outflow element; each of said outflow elements containing a collecting trough formed by said base portion; said collecting trough descending towards the interior of said inflow channel means; said collecting trough serving for the withdrawal of water which has been removed at the related outlet element; each of said outlet elements has an inlet opening; a plurality of ribs arranged at least at the region of the inlet opening of the related outlet element; said ribs being arranged so as to protrude from the base portion of the related outlet element and being disposed in spaced relationship from one another and extending essentially in the lengthwise direction of the related outlet element; and said plurality of ribs extend within the interior of the inflow channel means and subdivide the collecting trough into individual return flow channels.

Claim 6
Dependent Claim
15 words
The air distribution apparatus as defined in claim 4, wherein: said ceiling portion is arched.
Claim 7
Dependent Claim
86 words
The air distribution apparatus as defined in claim 5, wherein: said inflow channel means possesses a substantially oval cross-section; said inflow channel means including side walls which interconnect the arched ceiling portion and an arched base portion of said inflow channel means; said base portion of said inflow channel means being arched in order to serve as return flow channel means for separated water; and at least one of the side walls of the inflow channel means being provided with receiving openings for said outlet elements.
Claim 8
Dependent Claim
24 words
The air distribution apparatus as defined in claim 6, wherein: the throughflow cross-section of the inflow channel means continuously decreases in the airflow direction.
Claim 9
