Abstract: A combined toilet grey water system for passenger transportation vehicles such as aircrafts includes a toilet bowl for receiving waste water and a basin for receiving grey water. Moreover, the system includes a flushing line and a flushing valve with an inlet and an outlet. The outlet of the flushing valve is connectable to a vacuum waste water system. The inlet of the flushing valve is connected via the flushing line to the toilet bowl. Therein, the basin is connected to the flushing line in such a way that the basin is connectable to the vacuum waste water system.

Abstract: The system for flushing a vacuum toilet contains a urinal basin having a drain, which is connected to a drain line, and a bypass line, into which the drain line discharges, and which is connectable via a suction valve to a vacuum system. By generating a main air current in the bypass line and a secondary air current in the drain line, a noise emission in the area of the urinal basin may be significantly reduced.

Abstract: A system for flushing a vacuum toilet contains a flushing water reservoir container, which may be filled with flushing water, a toilet bowl, which is connectable using a vacuum wastewater line and via a flushing valve to a vacuum system, and a spray device, situated in the toilet bowl, which is connected via a Venturi nozzle to the flushing water reservoir container. A partial vacuum is generated in the vacuum wastewater line when the flushing valve is open, which generates an airflow, by which flushing water contained in the flushing water reservoir container is suctioned, sprayed via the spray device into the toilet bowl, and suctioned into the vacuum wastewater line.

Abstract: A closing device for a vacuum user system or vacuum toilet system of an aircraft that makes it possible to quickly open and close a pipe connection piece in a vacuum user system or in a vacuum toilet system of an aircraft. The closing device comprises a cover; a closing element that can be inserted into the pipe connection piece and is connected to the cover by a spacer and is designed such that it substantially fully covers a cross section of the pipe connection piece; a sealing bellows located between the cover and the closing element and that at least partly encloses the spacer, wherein the sealing bellows comprises a sealing face; and an element that is movable in relation to the cover, which element is movable from a first position to a second position, wherein the movable element engages the sealing bellows such that the sealing face of the sealing bellows in the second position has a greater extension in a plane across the spacer than it does in the first position.

Abstract: The present invention relates to an arrangement of line connections for installations in an aircraft passenger cabin. The arrangement comprises a line connection element for accommodating several line connections; wherein the line connection element has a fixed position in the floor grid; wherein the line connections are adaptable to system lines of aircraft systems; and wherein the installations are adaptable by way of flexible inlet lines on the line connection element.

Abstract: A shower drainage outlet for a shower tub in an aircraft is stated, which shower drainage outlet comprises three parts that can be displaced, angled or rotated in relation to one another. In this way horizontal, vertical and angular tolerances can be compensated for. Furthermore, the shower drainage outlet is designed to be inserted through an opening in the floor region of the aircraft.

Abstract: The invention relates to a tube assembly for connecting a first tube to a second tube, wherein a connection end of the first tube and a connection end of the second tube form a swivel joint, a rotational axis of the swivel joint and a tube axis of the first and the second tube form an angle ?, and the first tube is rotatable relative to the second tube in the region of between 0° and 2?.

Abstract: A device to diagnose a vacuum system comprises a pipe with a first opening that can be closed by a hingable cover, and a second opening that is designed to establish a pressure-proof connection to the vacuum system. The diagnostic device may be operated in a volume-flow mode in which the cover is open in order to determine a volume flow in the base body, and in a negative-pressure mode in which the cover is closed so as to allow to draw conclusions about the available pressure difference.
