Ventilation valve arrangement and transport container with a ventilation valve arrangement

摘要

The invention concerns a ventilation valve arrangement (1) with two valve openings (5, 6) in a valve plate (3), the opening degrees of said openings being controllable by means of a valve element, which is rotatable in relation to the valve plate (3). 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 (5, 6) a ventilation channel (9) is arranged, whose flow cross-section is adjustable by means of a motor controlled valve (10). The ventilation valve arrangement (1) can be dimensioned so that at the same time it serves as underpressure valve for a transport container.
