Abstract: A discharge valve is disclosed for use in a vacuum toilet system having a waste receptacle defining an outlet and a sewer line placeable under partial vacuum. The discharge valve comprises a housing defining an inlet and an outlet, and a rotatable discharge valve member disposed in the housing for selectively establishing fluid communication between the inlet and the outlet. A periphery of the disk valve member being formed with a series of gear teeth. An actuator is provided having a rotatable spur gear adapted to engage the periphery of the discharge valve member.

Abstract: A rinse fluid valve for use in a vacuum toilet system is disclosed. The vacuum toilet system includes a waste receptacle with a rinse fluid dispenser associated therewith and a source of rinse fluid. The rinse fluid valve has a housing with an inlet in fluid communication with the rinse fluid source and an outlet in fluid communication with the rinse fluid dispenser. A flow path extends from the inlet to the outlet. A moveable rinse fluid valve member is disposed in the flow path and movable between open and closed positions. A fuse valve is also disposed in the flow path and has a normally open position to allow fluid flow therethrough. The fuse valve is actuatable to a closed position after a desired volume of fluid has passed therethrough, thereby to cease rinse fluid flow through the flow path.

Abstract: A vacuum bowl assembly for use in a vacuum toilet positioned on a support surface and having a discharge valve. The vacuum bowl assembly comprises a frame having a bottom member adapted to engage the support surface, and a top member defining a shoulder. A removable bowl is provided having a flange extending about an upper edge sized to engage the shoulder, and an outlet adapted for fluid communication with the discharge valve.

Abstract: A modular vacuum toilet, and a method of servicing such a toilet, are disclosed. The toilet is used with a vacuum toilet system having a sewer line placeable under partial vacuum pressure and a source of rinse fluid. The modular vacuum toilet comprises a frame and a removable bowl engaging and supported be the frame, the bowl defining an outlet and having a rinse fluid dispenser associated therewith. The modular vacuum toilet also has a valve set module. The valve set module includes a discharge valve having an inlet in fluid communication with the bowl outlet, an outlet in fluid communication with the sewer line, and a movable discharge valve member disposed between the discharge valve inlet and outlet. A rinse fluid valve is also incorporated into the valve set module and has an inlet in fluid communication with the source of rinse fluid, an outlet in fluid communication with the rinse fluid dispenser, and a movable rinse fluid valve member disposed between the rinse fluid valve inlet and outlet.
