Abstract
A closure element is provided for a fuel tank of a motor vehicle, in which tank an at least slight excess pressure and/or vacuum may exist. An indication is provided on the closure element, by which indication the operator is informed of the presence of excess pressure and/or vacuum in the tank. The indication takes place mechanically by way of a mechanical pressure sensor, specifically with respect to the presence of essentially ambient pressure or excess pressure by use of different colors. For this purpose, an indicating dial can be provided in the closure element, which indicating dial can be rotated by way of a pin displaceable against a spring force under the influence of the pressure existing in the tank. A jacket segment being recognizable by the operator through a window.
