<p>The feed system is for a liquid stored in a reservoir. The liquid is drawn from the reservoir by a pump. It incorporates a portable reservoir for the liquid, of standard size, and which is used for transporting the liquid. A combined drainage and sealing device connects the reservoir to the pump (3). The drainage and sealing device can consist of a cap with sealing devices (2) identical to those (5) on the reservoir cap, together with drainage and vent pipes passing through the cap and fixed to it. The drainage pipe (6) can be extended by two flexible pipes, one running down to the bottom of the reservoir (1), and the other connected to the pump inlet.</p> |
