| titleOfInvention | Vacuum toilet system |
| abstract | A vacuum toilet assembly including a vacuum toilet (11) and a vacuum tankn(12) (e.g. a combined holding and vacuum tank) uses a simple air pump (14) tonremove air from the tank (12) to create a partial vacuum. The air pump (14) isncapable of achieving about ten inches mercury of vacuum in an empty 9.5 gallonnvacuum tank in roughly one minute, and can pump at least about one liter ofnliquid per minute. A combined sound muffler and odor filter (19) and/or rat-tailncheck valve and noise reducer, is/are connected to the outlet (17) from the airnpump (14). The pump (14) comprises a powered reciprocating diaphragm pumpnhaving a reciprocating diaphragm (24) powered by an electric motor (28) andnoppositely directed first and second disk valves (34, 35). The disk valves havenelastomeric disk valve elements die-cut from flat sheets which co-operate withnperforated concave surfaces in a dividing wall (38) in the pump housing (14). |
