Total Claims: 9
Claim 1
Independent Claim
253 words
A control body for sanitary single handle mixing sets, for mixing hot and cold water, comprising, a housing having an outlet and a control chamber connected to said outlet, a top and intermediate disc in said control chamber which are relatively slidably movable in respect to each other and whose position relative to each other and to said housing is determinative for both the volume and ratio of the mixture of the hot and cold water, said housing having a separate hot and cold water passage, said intermediate disc having intermediate hot and cold water passages which are alignable up to selected flow areas with said hot and cold water passages of said housing, with said top disc being provided with a surface channel through which separate hot and cold water passages of the underlying intermediate disc are connectable to said outlet, and wherein, said top and intermediate discs define a cross-flow channel therebetween having projections extending into said cross-flow channel from the bottom of said top disc up to a part of the total height of said channel and, transversely, to the flow direction, so as to provide numerous flow interruptions in said channel, said intermediate disc and an adjacnet disc portion of said top disc being made of ceramic material, said top disc including an uppermost disc portion with said adjacent disc portion being between said uppermost disc portion and said intermediate disc, said uppermost disc portion being made of a plastic material and defining the bottom of said cross-flow channel.
Claim 2
Dependent Claim
253 words
A control body for sanitary single handle mixing sets, for mixing hot and cold water, comprising, a housing having an outlet and a control chamber connected to said outlet, a top and intermediate disc in said control chamber which are relatively slidably movable in respect to each other and whose position relative to each other and to said housing is determinative for both the volume and ratio of the mixture of the hot and cold water, said housing having a separate hot and cold water passage, said intermediate disc having intermediate hot and cold water passages which are alignable up to selected flow areas with said hot and cold water passages of said housing, with said top disc being provided with a surface channel through which separate hot and cold water passages of the underlying intermediate disc are connectable to said outlet, and wherein, said top and intermediate discs define a cross-flow channel therebetween having projections extending into said cross-flow channel from the bottom of said top disc up to a part of the total height of said channel and, transversely, to the flow direction, so as to provide numerous flow interruptions in said channel, said intermediate disc and an adjacnet disc portion of said top disc being made of ceramic material, said top disc including an uppermost disc portion with said adjacent disc portion being between said uppermost disc portion and said intermediate disc, said uppermost disc portion being made of a plastic material and defining the bottom of said cross-flow channel.
Claim 3
Dependent Claim
19 words
A control body, as claimed in claim 1, wherein said pins have smooth outer surfaces and a rounded cross-section.
Claim 4
Dependent Claim
28 words
A control body, as claimed in claim 1, wherein said projections comprise ribs which extend in the main flow direction in the cross-channel and have smooth outer surfaces.
Claim 5
Dependent Claim
28 words
A control body, as claimed in claim 1, wherein said projections terminate at a small distance from the plane of mutual contact of said top and intermediate discs.
Claim 6
Dependent Claim
81 words
A control body as claimed in claim 1, including a bottom disc mounted in said chamber against rotation in respect to said housing having respective hot and cold water passages overlying said housing hot and cold water passages over which said intermediate disc is movable, said intermediate disc and said bottom disc passages for the hot and cold water being regulated in respect to area by alignment of the passages by rotation of said intermediate disc relative to said bottom disc.
Claim 7
Dependent Claim
43 words
A control body, as claimed in claim 1, wherein said cross-flow channel includes two branches united at an obtuse angle and extending in a direction of extension of the channel branches transverse to an extension of said intermediate hot and cold water passages.
Claim 8
Dependent Claim
19 words
A control body, as claimed in claim 1, wherein said projections form a part of said uppermost disc portion.
Claim 9
Dependent Claim
120 words
A control body, as claimed in claim 1, including a cartridge cap in said housing connected to said intermediate disc, a control lever mounted on said cartridge cap and being movable to rotate said cartridge cap with said intermediate disc to change the position of said intermediate disc in respect to the hot and cold water passages, said cartridge cap including a cylindrical portion in said control chamber of said housing surrounding said top and intermediate discs, and a tubular portion extending upwardly in said housing, said lever being pivoted to said tubular portion of said cartridge cap and having a spherical skirt portion overlying said cartridge cap, said housing having a sealing lip engaged with said spherical skirt portion.
