Abstract
A non-return valve for a fuel tank, the valve comprising a substantially tubular body and a deformable shutter member fixed to said body, said shutter member being formed integrally by molding a plastics material and being shaped in such a manner as to return under its own elasticity into a shut position, with the valve body serving as a seat, whenever the shutter member is at rest and the pressure of fuel is no longer sufficient to overcome the elastic return action of the shutter member.
