Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
A hydraulic mount assembly, comprising: a pair of mounting members; a hollow body connected to said mounting members; a resilient diaphragm closing said hollow body and forming therewith a closed cavity that is filled with an electro-rheological fluid; means for partitioning said cavity into a primary chamber and a secondary chamber enclosed by said diaphragm, said partitioning means including upper and lower conductive plates defining a cell therebetween, each plate further including a fluid flow orifice connecting said chambers through said cell so as to effect damping; a substantially continuous, conductive intermediate plate mounted in said cell between said upper and lower plates; insulated mounting means upon which said intermediate plate is mounted to said partitioning means; and means for applying a voltage to said electro-rheological fluid across said intermediate plate and said partitioning means including said upper and lower plates so as to selectively vary viscosity of said fluid and thus the damping of said hydraulic mount assembly.
Claim 2
Dependent Claim
159 words
A hydraulic mount assembly, comprising: a pair of mounting members; a hollow body connected to said mounting members; a resilient diaphragm closing said hollow body and forming therewith a closed cavity that is filled with an electro-rheological fluid; means for partitioning said cavity into a primary chamber and a secondary chamber enclosed by said diaphragm, said partitioning means including upper and lower conductive plates defining a cell therebetween, each plate further including a fluid flow orifice connecting said chambers through said cell so as to effect damping; a substantially continuous, conductive intermediate plate mounted in said cell between said upper and lower plates; insulated mounting means upon which said intermediate plate is mounted to said partitioning means; and means for applying a voltage to said electro-rheological fluid across said intermediate plate and said partitioning means including said upper and lower plates so as to selectively vary viscosity of said fluid and thus the damping of said hydraulic mount assembly.
Claim 3
Dependent Claim
161 words
A hydraulic mount assembly, comprising: a pair of mounting members; a hollow body connected to said mounting members; a resilient diaphragm closing said hollow body and forming therewith a closed cavity that is filled with an electro-rheological fluid; means for partitioning said cavity into a primary chamber and a secondary chamber enclosed by said diaphragm, said partitioning means including upper and lower conductive plates defining a cell therebetween, each plate further including a fluid flow orifice connecting said chambers through said cell so as to effect damping; a substantially continuous, conductive intermediate plate having a peripheral skirt around the marginal edge so as to form a dome shape, said intermediate plate being insulatingly mounted in said cell between said upper and lower plates; and means for applying a voltage to said electro-rheological fluid across said intermediate plate and said upper and lower plates so as to selectively vary viscosity of said fluid and thus the damping of said hydraulic mount assembly.
Claim 4
Dependent Claim
161 words
A hydraulic mount assembly, comprising: a pair of mounting members; a hollow body connected to said mounting members; a resilient diaphragm closing said hollow body and forming therewith a closed cavity that is filled with an electro-rheological fluid; means for partitioning said cavity into a primary chamber and a secondary chamber enclosed by said diaphragm, said partitioning means including upper and lower conductive plates defining a cell therebetween, each plate further including a fluid flow orifice connecting said chambers through said cell so as to effect damping; a substantially continuous, conductive intermediate plate having a peripheral skirt around the marginal edge so as to form a dome shape, said intermediate plate being insulatingly mounted in said cell between said upper and lower plates; and means for applying a voltage to said electro-rheological fluid across said intermediate plate and said upper and lower plates so as to selectively vary viscosity of said fluid and thus the damping of said hydraulic mount assembly.
Claim 5
Dependent Claim
46 words
The hydraulic mount assembly disclosed in claim 2 wherein one of said upper and lower plates of said partitioning means includes a substantially continuous channel, said skirt of said intermediate plate extending toward said channel so as to define a tortuous pathway for electro-rheological fluid flow.
