    摘要： A vacuum toilet system comprises a toilet bowl having a cover mounted for movement relative to the toilet bowl between an open position and a closed position, the cover being in at least partially sealing relation with the rim when in the closed position. A liquid supply opening is provided for introducing liquid into the toilet bowl when the cover is in the closed position. A discharge valve connects the outlet opening of the toilet bowl to a sewer pipe, in which a partial vacuum can be established. A reservoir has an inlet opening for receiving rinse liquid and an outlet opening in communication with the liquid supply opening. The inlet opening of the reservoir is exposed to substantially the same pressure as the liquid supply opening when the toilet bowl cover is in the open position and the discharge valve is closed. Rinse liquid is drawn from the reservoir into the toilet bowl by way of the liquid supply opening when the discharge valve is open and the cover is in the closed position.

    摘要： A vacuum toilet system comprises a waste-receiving bowl defining an interior space for receiving waste material. A sewer pipe defines an interior space that can be placed at a pressure that is lower than that in the interior space of the waste-receiving bowl, and a discharge valve is connected between the outlet of the waste-receiving bowl and the sewer pipe for controlling passage of material between the waste-receiving bowl and the sewer pipe. A rinse liquid valve controls supply of rinse liquid to the waste-receiving bowl. A controller is responsive to a user stimulus to open and close the discharge valve in accordance with a predetermined cycle, and to open the rinse liquid valve during at least the interval during which the discharge valve is being opened.

    摘要： A vacuum toilet system comprises a toilet bowl having an outlet opening, a sewer pipe having an interior space, a discharge valve connecting the outlet opening of the toilet bowl to the sewer pipe, and a source of partial vacuum for establishing a lower pressure in the interior space of the sewer pipe than in the toilet bowl. A nozzle defines a rinse liquid outlet for introducing liquid into the toilet bowl. A container for reagent is in communication with the rinse liquid outlet. Reagent is introduced into the toilet bowl by way of the rinse liquid outlet in timed relationship to introduction of rinse liquid into the toilet bowl.
