WIPER ASSEMBLY FOR FUEL LEVEL INDICATION

摘要

A fuel level sensor includes a wiper support with metal wiper contacts. A rotatable shaft holds the wiper support and a seal assembly is provided in which the wiper support is disposed. The seal assembly includes a frame and a cover that are sealed together along respective peripheries with the wiper support being sandwiched therebetween. The shaft extends into and through an opening formed in the cover and is rotatable therein with a holder covering an end of the shaft and sealing the opening in cooperation with the cover. The frame is formed with a diaphragm above the wiper shaft that is deflectable to facilitate assembly and allow the sensor to compensate for pressure changes in a fluid tank in which the sensor can be disposed.
