Abstract
Abstract To provide only dry steam to a steam appliance, under controlled conditions, a housing block is formed with steam inlet and outlet flanges or the like, a filter being removably located in the housing immediately behind the inlet and a control valve located in the housing immediately behind the outlet; the housing forms a space between the filter and the control valve to dry admitted steam, including a condensate collecting region at the bottom thereof which terminates in an outwardly accessible drain opening. The drying chamber formed by the housing is separated or subdivided into compartments by at least one impact or deflection plate against which the steam is guided in order to separate the drying chamber into a pre-drying and a post-drying chamber and efficiently remove moisture and water droplets from the steam introduced into the system.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
Control system for steam supplied apparatus, particularly to supply dry steam thereto from a supply comprising a housing block (1) and defining therein a steam drying chamber (12, 13); a steam inlet means (2) communicating with the interior of the housing; a steam outlet means (3) communicating with the interior of the housing and providing for removal of dried steam therefrom; a filter (8) removably located in the housing immediately behind the steam inlet means (2); a control valve (9) removably located in the housing immediately in advance of the outlet means (3); an impingement wall (20) subdividing the steam drying chamber into a pre-drying chamber (12) and a post-drying chamber (13), the pre-drying chamber being adjacent the filter (8) and the post-drying chamber being adjacent the valve (9); means (21) forming a steam communication between the pre-drying and post-drying chambers (12, 13); and a condensate collecting zone (15) located at the bottom portion of the housing including a condensate outlet duct (16) and in fluid communication with at least said pre-drying chamber.
Claim 2
Dependent Claim
173 words

Claim 3
Dependent Claim
33 words
System according to claim 1, wherein the housing is formed with an inclined portion (6) located immediately adjacent to the inlet stub (2), said filter (8) being located in said inclined portion (6).
Claim 4
Dependent Claim
29 words
System according to claim 1, further including a cleaning outlet stub (18) formed in the housing and communicating with the condensate collecting zone (15) to provide exterior access thereto.
Claim 5
Dependent Claim
24 words
System according to claim 1, wherein the botton wall of at least the post-drying chamber is inclined with respect to the condensate outlet (16).
Claim 6
Dependent Claim
43 words
System according to claim 1, where the means communicating between said chamber portions (12, 13) comprises an opening (21) located in the upper region of the wall (20) to permit passage of steam from the pre-drying chamber (12) to the post-drying chamber (13).
Claim 7
Dependent Claim
43 words
System according to claim 5, further comprising means forming a zone of restricted cross section, having a cross-sectional area which is small with respect to the cross section of said pre-drying chamber (12) to accelerate the flow of steam through said opening (21).
Claim 8
Dependent Claim
42 words
System according to claim 1, further including steam flow path guide means (24) located between the filter (8) and the impingement wall (20) and guiding the flow of steam to direct the steam from the filter to impinge on said wall (20).
Claim 9
Dependent Claim
25 words
System according to claim 7, wherein the wall is formed, in the zone of impingement by the steam, with a region of increased surface area.
Claim 10
Dependent Claim
43 words
System according to claim 8, wherein the region of increased surface area comprises projections (23) projecting from the major surface of the wall (20) to assist in precipitation of water droplets from the steam impinging against said surface area of the wall (20).
Claim 11
Dependent Claim
89 words
System according to claim 9, wherein the means communicating between said chamber portions (12, 13) comprises an opening (21) located in the upper region of the wall (20) to permit passage of steam from the pre-drying chamber (12) to the post-drying chamber (13); the housing is formed with an inclined portion (6) located immediately adjacent the inlet stub (2), said filter (8) being located in said inclined portion (6); and wherein the bottom wall of at least the post-drying chamber is inclined with respect to the condensate outlet (16).
