Abstract
Abstract A tubular inlet for a fuel tank includes a transverse baffle having an opening sized to receive a fuel nozzle of a determined diameter, and apertures located laterally of said opening and which permit viewing of the tank interior when a nozzle is inserted into the said opening, the structure optionally including a movable shutter which is resilient biased to a position in which it closes said opening, the shutter being movable by said nozzle against said bias.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
A fuel inlet for a fuel tank, said fuel tank comprising a saddle form tank having an middle upwardly concave bottom portion, said inlet comprising: a tubular member extending through an upper wall of said tank centrally thereof and rigidly supported thereby; and a baffle plate located within said tubular member and extending transversely thereof, the baffle plate having an opening sized to accept a fuel nozzle of a determined diameter and reject a fuel nozzle of a diameter larger than said determined diameter, and having a plurality of apertures located laterally of and symmetrically surrounding said opening permitting viewing of the tank interior, said apertures being insufficient in cross-sectional area to accommodate the passage therethrough of a conventional fuel nozzle.
Claim 2
Dependent Claim
