Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 135 words
A fuel injector nozzle, in which a housing with an inlet for pressurized fuel has at one end an 15 electrically conductive spray tip body which is connectible to one end of an electrical test circuit and within which an electrically conductive injection valve is reciprocable relative to a valve seat in said body to open or close a spray tip outlet 20 at the free end thereof, a spring and an abutment operatively connected to said housing and said injection valve being arranged so as normally to bias said valve to close said outlet, and said ' abutment being connectible to the opposite end of 25 said test circuit and including insulation arranged so as electrically to insulate said spray tip body from said injection valve when the valve is in its open position.
Claim 2
Dependent Claim 135 words
A fuel injector nozzle, in which a housing with an inlet for pressurized fuel has at one end an 15 electrically conductive spray tip body which is connectible to one end of an electrical test circuit and within which an electrically conductive injection valve is reciprocable relative to a valve seat in said body to open or close a spray tip outlet 20 at the free end thereof, a spring and an abutment operatively connected to said housing and said injection valve being arranged so as normally to bias said valve to close said outlet, and said ' abutment being connectible to the opposite end of 25 said test circuit and including insulation arranged so as electrically to insulate said spray tip body from said injection valve when the valve is in its open position.
Claim 3
Dependent Claim 104 words
A fuel injection nozzle according to claim 1, 30 in which said nozzle housing includes a cap having a spill tube extending therefrom fixed to the end of said spray tip body opposite said spray outlet, said abutment being of electrical conductive material and having a central through aperture therein, and 35 said spring has therein a bushing of electrical conductive material having a central guide bore therethrough slidably receiving the end of said injection valve opposite said valve seat, said spring being operatively connected to said 40 bushing so as normally to bias it into seating contact with one side of said abutment.
Claim 4
Dependent Claim 65 words
A fuel injection nozzle according to claim 2, in which said cap includes insulation arranged to insulate said spill tube electrically from said spray 45 tip body, said spill tube being electrically conductive and positioned to abut the opposite side of said abutment so that said injection valve-is operatively connectible to said electrical test circuit via said bushing, said abutment and said 50 spill tube.
Claim 5
Dependent Claim 84 words
A fuel injection nozzle according to claim 2, in which said insulation is a layer of insulating material covering all but the said one side of said abutment engaged by said bushing, and said cap 55 has an aperture therethrough aligned with a portion of said abutment to enable a pointed electrical probe of said electrical test circuit to be inserted through said aperture to penetrate said layer of insulating material and effect an electrical 60 connection with the conductive material of said abutment.
Claim 6
Dependent Claim 69 words
A fuel injection nozzle according to claim 2, in which said insulation includes insulating washers positioned on opposite sides of said 65 abutment so that said abutment is positioned between and electrically insulated from said cap and said spray tip body, and said cap has an aperture therethrough to enable an electrical connection to be made from said abutment to the 70 opposite end of the electrical test circuit.
Claim 7
Dependent Claim 59 words
A fuel injection nozzle constructed and adapted to operate substantially as hereinbefore described with reference to and as shown in Figure 1,2 or 3 of the accompanying drawings. Printed for Her Majesty's Stationery Office by the Courier Press, Leamington Spa, 1980. Published by the Patent Office, 25 Southampton Buildings, London, WC2A 1 AY, from which copies may be obtained.
