Abstract
A fuel gauging system for a motor vehicle fuel tank, including a housing (100) supporting a resistive element (200), an arm (300) pivotally mounted on the housing (100) and comprising at least one cursor (350) engaging the resistive element (200), and a lever (400) provided with a float connected to the arm (300) for monitoring the movements thereof. The system includes a housing (100) and an arm (300) which comprise complementary rotational guides (120, 310) and structure (316, 317, 318, and 319) to enable translation of the arm (300) on the housing (100). The arm (300) is combined with an L-shaped lever (400) so that one of the sections (420) defines the pivot axis of the device.
Claims8
A fuel gauging device for a motor vehicle tank comprising:
- a housing having a resistive element, an arm pivotally mounted to the housing and having 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,
- wherein the housing arm comprise complementary rotational-guidance means for translationally immobilizing the arm on the housing,
- wherein the means for translationally immobilizing includes two elastic snap-fit tabs, each having an end and a tooth at its end, each secured to the arm and positioned to diametrically opposed relative to the axis O—O of pivoting of the arm, said snap-fit tabs secured to the arm being adapted to interact with a bushing secured to the housing,
- said lever including an L-shaped lever having two branches received on said arm so that one of the branches of the lever provides the functional pivot axis of the device,
- wherein said bushing includes an internal central passage that defines a diameter, wherein the diameter complements the branch of the lever forming the functional pivot axis of the device.
