A tank connection (8) is connected with the tank, and a filter connection (9) is connected with an activated charcoal filter. The connections point in lateral directions during downward installation of a valve unit (1), and are arranged at or at the proximity of a lower side of the valve unit. One of the controlling valves has two chambers that are separated by a membrane.",
