Abstract

A closing device for the filler neck of a motor vehicle tank, in which device an orifice of the filler neck, opening into the tank interior can be closed by means of a cap which can be placed sealingly onto the orifice edge under a closing force. The closing force is exerted by a spring. The nozzle of a filling pump to be introduced into the filler neck can operate opening movement of the cap. The cap can be displaced between the closing and the opening position via an actuating mechanism by means of a variable transmission ratio having a value decreasing from the closing position of the cap to its open position and by means of a variable closing force having a value increasing from the open position of the cap to the closing position.
