Abstract
The invention concerns a ventilation valve arrangement () with two valve openings () in a valve plate (), the opening degrees of said openings being controllable by means of a valve element, which is rotatable in relation to the valve plate (). It is endeavored to create a large range of control opportunities in a cost-efficient manner. For this purpose it is provided that in parallel to at least one valve opening () a ventilation channel () is arranged, whose flow cross-section is adjustable by means of a motor controlled valve (). The ventilation valve arrangement () can be dimensioned so that at the same time it serves as underpressure valve for a transport container.
