Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A fuel rail assembly comprising means defining an elongated hole, a carrier inserted into said hole, said carrier including electric operated fuel injectors that have nozzles which are sealed to holes in the wall of said means for injecting fuel therefrom, electrical terminations providing for the fuel rail assembly to be connected to a source of electric power and signals for operating the fuel injectors, said terminations being disposed in an end closure and electrical connector member that forms a sealed closure with an end of said hole, said terminations have exterior portions for mating connection with complementary terminations providing such electric power and signals and interior portions making electric connection with conductors on said carrier via which said signals and electric power are delivered to said carrier to operate said fuel injectors.
Claim 2
Dependent Claim
133 words
A fuel rail assembly comprising means defining an elongated hole, a carrier inserted into said hole, said carrier including electric operated fuel injectors that have nozzles which are sealed to holes in the wall of said means for injecting fuel therefrom, electrical terminations providing for the fuel rail assembly to be connected to a source of electric power and signals for operating the fuel injectors, said terminations being disposed in an end closure and electrical connector member that forms a sealed closure with an end of said hole, said terminations have exterior portions for mating connection with complementary terminations providing such electric power and signals and interior portions making electric connection with conductors on said carrier via which said signals and electric power are delivered to said carrier to operate said fuel injectors.
Claim 3
Dependent Claim
22 words
A fuel rail assembly as set forth in claim 1 in which said carrier includes a circuit board assembly contains said conductors.
Claim 4
Dependent Claim
47 words
A fuel rail assembly as set forth in claim 2 in which said conductors are on a flat surface portion of said circuit board assembly and said interior portions of said terminations fit over an edge of said circuit board assembly to make connection with said conductors.
Claim 5
Dependent Claim
32 words
A fuel rail assembly as set forth in claim 1 including a through-nipple in said end closure and electrical connector member for conducting liquid fuel flow into or out of said hole.
Claim 6
Independent Claim
92 words
The method of making a fuel rail assembly which comprises inserting a carrier into a hole, said carrier comprising fuel injectors and electrical conductors forming terminations, and closing an end of said hole with an end closure and electrical connector member to close said end and in the process establish electrical continuity between a corresponding one of each of said terminations and a corresponding one of terminals that extend through said member to form a corresponding external termination with which a corresponding mating termination from a wiring harness connector can be made.
Claim 7
Independent Claim
92 words
The method of making a fuel rail assembly which comprises inserting a carrier into a hole, said carrier comprising fuel injectors and electrical conductors forming terminations, and closing an end of said hole with an end closure and electrical connector member to close said end and in the process establish electrical continuity between a corresponding one of each of said terminations and a corresponding one of terminals that extend through said member to form a corresponding external termination with which a corresponding mating termination from a wiring harness connector can be made.
Claim 8
Dependent Claim
144 words
A fuel rail assembly comprising a walled fuel rail member comprising a main fuel passage, including an opening, that serves one or more electric operated fuel injectors that are disposed within said passage and have nozzles which are sealed to holes in the wall of said member for injecting fuel therefrom, electrical terminations providing for the fuel rail assembly to be connected to a source of electric power and signals for operating the fuel injectors, said electrical terminations being disposed in an end closure and electrical connector member that forms a sealed closure with said opening of said passage, said terminations have exterior portions for mating connection with complementary terminations providing such electric power and signals and interior portions making electric connection with conductors which extend along said member and via which said signals and electric power are delivered to operate said fuel injectors.
Claim 9
Dependent Claim
144 words
A fuel rail assembly comprising a walled fuel rail member comprising a main fuel passage, including an opening, that serves one or more electric operated fuel injectors that are disposed within said passage and have nozzles which are sealed to holes in the wall of said member for injecting fuel therefrom, electrical terminations providing for the fuel rail assembly to be connected to a source of electric power and signals for operating the fuel injectors, said electrical terminations being disposed in an end closure and electrical connector member that forms a sealed closure with said opening of said passage, said terminations have exterior portions for mating connection with complementary terminations providing such electric power and signals and interior portions making electric connection with conductors which extend along said member and via which said signals and electric power are delivered to operate said fuel injectors.
Claim 10
Dependent Claim
20 words
A fuel rail assembly as set forth in claim 6 in which said conductors are disposed entirely within said passage.
