Level sensor for a fuel tank
View Patent ↗In a level sensor ( 2 ) for a fuel tank, one end of a lever wire ( 7 ) is located at a distance from a bearing ( 11 ) of a bracket ( 5 ). The bracket ( 5 ) has two limbs ( 12, 13 ) of which one holds the lever wire ( 7 ) and the other controls the signal transmitter ( 8 ). This enables the level sensor ( 1 ) to be calibrated in a particularly easy manner.
1. A level sensor for generating electrical signals as a function of a lever arm comprising:
(a) a float ( 4 ) having a float arm ( 7 ) attached to an end thereof;
(b) a support ( 6 ) for attachment to a side wall of a vehicle fuel tank;
(c) a bracket ( 5 ) having a first limb ( 12 ) and a second limb ( 13 );
(d) a bearing ( 11 ) pivotally joining the bracket ( 5 ) on the support ( 6 ) at a location between the first and second limbs; and
(e) means connecting the end of the float arm furthest from the float to first limb ( 12 ) at a location a predetermined distance from the bearing ( 11 ), whereby damaging vibration can be eliminated from the level sensor.
2. The level sensor as claimed in claim 1 , characterized in that the bracket ( 5 ) has two limbs ( 12 , 13 ) which project from the bearing ( 11 ), and in that the free end of the lever wire ( 7 ) is arranged on a first limb ( 12 ) and the second limb ( 13 ) is designed to actuate the signal transmitter ( 8 ).
3. The level sensor as claimed in claim 1 or 2 , characterized in that an angled section ( 14 ) of the free end of the lever wire ( 7 ) penetrates a recess ( 15 ) in the first limb ( 12 ) of the bracket ( 5 ), and in that the recess ( 15 ) is arranged at the end which is remote from the bearing ( 11 ) of the bracket ( 5 ).
4. The level sensor as defined in claim 3 , wherein a vibration damper ( 17 ) is arranged in the recess ( 15 ).
5. The level sensor as defined in claim 1 , wherein the lever wire ( 7 ) is arranged on that side of the support ( 6 ) which is remote from the signal transmitter ( 8 ).
6. The level sensor as defined in claim 4 , wherein two vibration dampers ( 17 ) are arranged on a section of the first limb ( 12 ) of the bracket ( 5 ), this section being routed parallel to the lever wire ( 7 ).
