The invention relates to a vacuum toilet system for a vehicle, especially for a passenger aircraft, comprising a plurality of toilets (1, 1'), a collecting tank (2), a pipe network (3) which connects the toilets to the collecting tank, and a vacuum generator (4) which is fluidically connected to the collecting tank. The pipe network (3) comprises at least one main pipe (5) and a plurality of branch pipes (6, 6'), via which the toilets (1, 1') are connected to the at least one main pipe (5). The branch pipes discharge into the main pipe at an acute angle formed with a component that is pointed in a delivery direction (A) in the main pipe (5). In addition, the branch pipes describe a curve (7, 7') in the proximity of the respective inflow thereof. The curvature mid-point (8, 8') of the respective center line (9, 9') of the curved sections (7, 7') of the branch pipes (6, 6') are located behind the respective inflow point (10, 10') of the center line (9, 9') in the main pipe (5) with regard to the delivery direction (A) in said main pipe (5).

L'invention concerne un système de toilettes à aspiration destiné à un véhicule, notamment à un avion de transport de passagers. Le système comprend une pluralité de toilettes (1, 1'), un récipient collecteur (2), un réseau de conduites (3) reliant les toilettes au récipient collecteur et un générateur d'aspiration (4) en communication fluidique avec le récipient collecteur (4). Le réseau de conduites (3) comprend au moins une conduite principale (5) et une pluralité de conduites secondaires (6, 6') qui relient les toilettes (1, 1') à au moins une conduite principale. Les conduites secondaires débouchent dans la conduite principale (5) en formant un angle aigu avec un composant dirigé dans le sens de transport à l'intérieur de ladite conduite et décrivent une courbe (7, 7') à proximité de leur embouchure. Le centre de courbure (8, 8') de chaque ligne médiane (9, 9') des sections courbes (7, 7') des conduites secondaires (6, 6') se trouve derrière le point d'embouchure (10, 10') de la ligne médiane (9, 9') dans la conduite principale (5) par rapport à la direction de transport (A) à l'intérieur de ladite conduite principale (5).
