Patent

CA 2198178

A vacuum sewage handling assembly particularly for boats and recreational vehicles or caravans has a minimum of components because the conventional vacuum and holding tanks have been combined into a single substantially unreinforced, non-cylindrical, all plastic tank. The tank has a contoured, convoluted, discontinuous surface (e.g. formed by grooves, channels, and other discontinuities) so that it has no continuous flat surface area of more than about 200 square centimeters The combined vacuum and holding tank may mount a vacuum pump, and optionally mounts a sewage discharge pump. The tank preferably has a generally parallelepiped configuration, and an interior volume of between about 45-65 liters, has a maximum vacuum level of about 26 cm of mercury, and is connected to other conventional portions of a vehicle toilet system, including outlets penetrating the exterior of the vehicle.

Égout à vide conçu particulièrement pour des bateaux et des véhicules de plaisance ou des roulottes. L'égout se compose d'un minimum d'éléments parce que l'enceinte à vide et la cuve de rétention ont été combinées en une seule cuve entièrement en plastique, essentiellement non renforcée et non cylindrique. La surface de la cuve est profilée, vrillée et discontinue (elle se compose par exemple de stries, de rainures, et d'autres discontinuités), de sorte que la cuve n'a pas de surface plate continue de plus d'environ 200 centimètres carrés. La cuve combinée peut être reliée à une pompe à vide et, facultativement, à une pompe d'évacuation des eaux usées. La cuve a une configuration généralement parallélépipédique, son volume intérieur se situe environ entre 45 et 65 litres, son niveau de vide est d'environ 26 cm de mercure et elle se rattache aux autres parties conventionnelles du système sanitaire d'un véhicule, y compris les sorties qui donnent sur l'extérieur du véhicule.
