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.
