Abstract
A vacuum plumbing system especially in an aircraft equipped with jet engines, is provided with a tap air supply source (4) that receives the tap air from the engine exhaust and is connected with a nozzle (1A) of at least one ejector or jet air pump (1) while the suction port (1C) of the pump (1) is connected through ducts or pipes (7, 11, 12) to a refuse collecting duct (15) either directly or indirectly through refuse collecting tank (9). Filters in the tank and conveying pumps are thus avoided.
