Abstract
Abstract This disclosure relates to an annular shoulder assembly for a rotating seal. The shoulder assembly has an annular reservoir connected to an annular cooling chamber. An annular orifice is provided between the reservoir and the cooling chamber to control the distribution of coolant supplied to the cooling chamber from the reservoir. The annular cooling chamber extends rearwardly from the front planar surface and the coolant fluid, by the centrifugal force exerted during rotation of the annular shoulder assembly, forms a uniform film on the annular walls of the chamber to cool the annular shoulder assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
245 words
An annular shoulder assembly for a rotating seal comprising, an annular body portion having an annular radially extending front planar surface, a substantially cylindrical inner surface and an annular outer surface, said front planar surface adapted to abut the planar surface of a seal ring biased against said front planar surface to provide a fluidtight seal therebetween upon rotation of one of said planar surfaces relative to the other planar surface, an annular reservoir in said body portion spaced inwardly from said body portion substantially cylindrical inner surface, said annular reservoir having a pair of diverging walls and a substantially conical shape in cross section, an annular chamber connected at one end to said reservoir and extending outwardly therefrom, said annular chamber having a pair of spaced walls inclined rearwardly relative to said planar front surface, a plurality of inlet passageways extending from said inner cylindrical surface into said reservoir and a plurality of outlet passageways extending from said outer annular surface to said annular chamber, an annular lip member between said annular reservoir and said annular chamber forming an orifice therebetween to control and distribute the amount of coolant fluid flowing into said chamber, and said inlet passageways arranged to supply a coolant fluid to said annular reservoir, said annulaR reservoir arranged to supply a preselected amount of coolant fluid to said chamber to extract heat from said body portion and said outlet passages arranged to conduct said coolant fluid from said annular chamber.
Claim 2
Dependent Claim
245 words
An annular shoulder assembly for a rotating seal comprising, an annular body portion having an annular radially extending front planar surface, a substantially cylindrical inner surface and an annular outer surface, said front planar surface adapted to abut the planar surface of a seal ring biased against said front planar surface to provide a fluidtight seal therebetween upon rotation of one of said planar surfaces relative to the other planar surface, an annular reservoir in said body portion spaced inwardly from said body portion substantially cylindrical inner surface, said annular reservoir having a pair of diverging walls and a substantially conical shape in cross section, an annular chamber connected at one end to said reservoir and extending outwardly therefrom, said annular chamber having a pair of spaced walls inclined rearwardly relative to said planar front surface, a plurality of inlet passageways extending from said inner cylindrical surface into said reservoir and a plurality of outlet passageways extending from said outer annular surface to said annular chamber, an annular lip member between said annular reservoir and said annular chamber forming an orifice therebetween to control and distribute the amount of coolant fluid flowing into said chamber, and said inlet passageways arranged to supply a coolant fluid to said annular reservoir, said annulaR reservoir arranged to supply a preselected amount of coolant fluid to said chamber to extract heat from said body portion and said outlet passages arranged to conduct said coolant fluid from said annular chamber.
Claim 3
Dependent Claim
51 words
An annular shoulder assembly for a rotating seal as set forth in claim 1 in which, said body portion front planar surface is arranged to rotate relative to said seal ring and centrifugally propel the coolant fluid through said chamber as a uniform film to extract heat from said body portion.
Claim 4
Dependent Claim
29 words
A shoulder assembly for a rotating seal as set forth in claim 2 in which, said annular reservoir extends longitudinally in said body portion toward said front planar surface.
Claim 5
Dependent Claim
54 words
An annular shoulder assembly for a rotating seal as set forth in claim 1 in which, one of said pair of spaced walls of said annular chamber forming a rearwardly extending annular front wall and upon rotation of said annular shoulder assembly the coolant fluid forms a uniform film on said annular front wall.
Claim 6
Dependent Claim
32 words
An annular shoulder assembly for a rotating seal as set forth in claim 1 in which said inlet passageways open into said reservoir at a location spaced from said annular lip member.
Claim 7
Dependent Claim
28 words
An annular shoulder assembly for a rotating seal as set forth in claim 1 in which the number of said inlet passageways exceeds the number of outlet passageways.
Claim 8
Dependent Claim
229 words
An annular shoulder assembly for a rotating seal as set forth in claim 1 in which, said body portion includes a shoulder face portion and a shoulder back portion, said shoulder face portion having said front planar surface and an annular lip portion forming a portion of said substantially cylindrical inner surface, said annular lip portion having an outer cylindrical surface, said inlet passageways extending through said annular lip portion, said cylindrical outer surface of said lip portion forming one of said walls of said reservoir, said shoulder face portion having a rear inclined annular surface forming one of said walls of said chamber and an annular rear recessed portion adjacent the periphery thereof, said shoulder back portion having an inner cylindrical surface and an inner annular front surface, said shoulder back portion having a forwardly extending annular protuberance with an inner inclined surface and an outer inclined surface, said inner surface of said annular protuberance forming one of said walls of said reservoir and said outer inclined surface forming one of said walls of said chamber, said shoulder back portion having a peripheral lip portion with said outlet passageways extending therethrough, said shoulder back portion positioned on said shoulder face portion with said annular peripheral lip portion positioned in said shoulder face portion peripheral recessed portion to form a shoulder assembly including a reservoir and a coolant chamber.
