ABSTRACT:
The present invention relates to the field of fuel gauging devices for motor vehicle tanks.
More specifically, the present invention relates to gauging devices of the known type comprising a housing which bears a resistive element, an arm mounted so that it can move on the housing and comprising at least one cursor which rests against the resistive element and a lever fitted with a float, connected to the arm for controlling the movements thereof.
Numerous devices of this kind have already been proposed.
Reference could, for example, be made to the documents FR-A-2661498, U.S. Pat. No. 4,870,861, DE-A-3627116, GB-A-2083628, FR-A-2533694, GB-A-1159806, GB-A-2048495, EP-A-0007072, FR-A-2364599, U.S. Pat. Nos. 1,771,794, and 3,200,646.
The present invention now has the object of improving the known fuel gauging devices.
In particular, the object of the present invention is to simplify the assembly of gauging devices.
Another object of the present invention is to limit the initial size of the housing which houses the resistive element so as, on the one hand, to make the tests prior to installation on vehicle easier, and on the other hand, make the devices easier to store.
Another object of the present invention is to improve the reliability of the known gauging devices.
These objects are achieved according to the present invention by means of a fuel gauging device, of the known type, comprising a housing which bears a resistive element, an arm mounted so that it can pivot on the housing and comprising at least one cursor which rests against the resistive element and a lever fitted with a float connected to the arm to control the movements thereof, characterized in that the housing and the arm comprise complementary rotational-guidance means, and means for translationally immobilizing the arm on the housing and that the arm is adapted to receive an L-shaped lever so that one of the branches of the lever provides the functional pivot axis of the device.
According to another advantageous feature of the invention, the means for translationally immobilizing the arm on the housing are formed of snap-fit tabs secured to the arm and adapted to interact with a bushing secured to the housing.
