<p>The device has a main liquid channel between a primary liquid container and an output point, a buffer container with a vent and connected to a main channel branching point so the main channel is preferentially filled before the secondary container, a valve between the primary container and branching point, a sensor for the level in the secondary container and a device for opening the valve in response to a defined level in the secondary container. The device has a main liquid channel between a primary container (10) for storing the liquid and an output point (22) for outputting the liquid, a secondary buffer container (26) with a vent and connected to a branching point in the main channel so that the main channel is preferentially filled before the secondary container, a valve (18) between the primary container and branching point, a sensor (30) for the level in the secondary container and a device for opening the valve in response to a defined level in the secondary container. Independent claims are also included for the following: a writing device for a liquid writing medium.</p> |
