Abstract
Abstract A plate-type electromagnetic fuel injector having a spacer (27) against which the armature (24) of the electromagnet (13,17) abuts, said spacer (27) being formed from a material which is non-magnetic, electrically insulating and dimensionally stable when subject to, and able to withstand, repeated impact loading by the armature of the electromagnet.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
62 words
A plate-type electromagnetic fuel injector characterized in that there is provided a spacer (27) against which the armature (24) of the electromagnet (13,17) abuts, said spacer (27) being formed from a material which is non-magnetic, electrically insulating, resultant to attack by the fuel and dimensionally stable when subject to, and able to. withstand, repeated impact loading by the armature of the electromagnet.
Claim 2
Dependent Claim
62 words
A plate-type electromagnetic fuel injector characterized in that there is provided a spacer (27) against which the armature (24) of the electromagnet (13,17) abuts, said spacer (27) being formed from a material which is non-magnetic, electrically insulating, resultant to attack by the fuel and dimensionally stable when subject to, and able to. withstand, repeated impact loading by the armature of the electromagnet.
Claim 3
Dependent Claim
20 words
An injector as claimed in claim 1, characterized in that the spacer (27) is formed from a synthetic resin material.
Claim 4
Dependent Claim
18 words
An injector as claimed in claim 2, characterized in that the synthetic resin material is a film-type polyester.
Claim 5
Dependent Claim
44 words
An injector as claimed in claim 2, characterized in that the synthetic resin material is a film-type polyester having a repeat unit of C 10 H 8 0 4 which is resistant to attack by petroleum hydrocarbon fuels and which is non-malleable in use.
Claim 6
Dependent Claim
16 words
An injector as claimed in claim 4, characterized in that the film-type polyester is polyethylene- terephthalate.
Claim 7
Dependent Claim
22 words
An injector as claimed in claim 2, characterized in that the synthetic resin is a so-called "paper" formed of an aromatic polyamide.
