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 endeavoured 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.
摘要:
The invention concerns a container floor plate (1), in particular for a refrigerated container, with an upper floor layer (2), a lower floor layer (3) and an intermediate insulating layer (8), support blocks (9) being located between the upper floor layer (2) and the lower floor layer (3). The purpose of the invention is to obtain a good insulation with a small mass. For this purpose, the lower floor layer (3) is provided with several transversal supports (10, 11), each support block (9) being supported on a transversal support (10).
