摘要： The invention relates to an odour seal for a vacuum toilet drain system whose cross section in the state of no throughflow tapers off in such a way in the downstream direction that the interior walls on the downstream end of the odour seal rest against each other so that the odour seal in a downstream direction allows throughflow while in the opposite direction it blocks throughflow, wherein the downstream end of the odour seal is closed in the state of throughflow and no throughflow of the odour seal. Furthermore, the invention relates to a drainage device comprising such an odour seal and a sieve which is arranged upstream of the odour seal. Moreover, the invention relates to a vacuum toilet system for an aircraft, comprising such an odour seal or a drainage device.
摘要翻译：本发明涉及一种用于真空马桶排水系统的气味密封件，其在不通流状态下的横截面沿下游方向逐渐变细，使得气味密封件下游端的内壁相互抵靠，使得下游方向的气味密封允许通过流动，而在相反方向上阻挡通流，其中气味密封件的下游端处于通流状态并且不通过气味密封件的流通。此外，本发明涉及包括这种气味密封件和布置在气味密封件上游的筛子的排水装置。此外，本发明涉及一种用于飞机的真空马桶系统，包括这种气味密封件或排水装置。

摘要： A one-way valve which can be utilized in a toilet, particularly in a urinal, to prevent return flow of malodorous gases from the sewage system into the room wherein the toilet is installed has a body which is confined in the toilet. The body carries two sheet- or panel-shaped valving elements at least one of which is resilient to yield to the flow of urine but normally sealingly engages the other element to prevent the flow of gases from the sewage system counter to the direction of flow of the urine. At least one marginal portion of the at least one valving element is free to move away from the corresponding marginal portion of the other element to also permit lateral outflow of urine when the one element is at least partially out of contact with the other element.

摘要： A backflow prevention device for use in wastelines and the like having a one piece yieldably deformable valving member which permits free flow of liquids in one direction but blocks the flow of liquids and gasses in the opposite direction. Fluid flow through the device is directly proportional to the fluid pressure exerted on the valving member.
