Fuel gauging and pressurizing system for automotive vehicle fuel tank and tank so equipped

摘要

The fuel metering and drawing system comprises a support base (130) fixed on the fuel tank wall and a metering and drawing set (120), comprising a pump and a fuel level detector, mounted on the support base and moved relative to it to the bottom of the tank. The support base and the gauging system are connected by two sets of guides. The first comprises a ball joint (125) engaged in a circular section chamber (150) enabling a translation and relative ball jointing. The second guide set comprises a structure (123) fixed to the base engaged in an oblong section chamber (140) enabling a translation and a clearance along a plane passing through the associated translation axis.
