Valve set for a vacuum toilet
First Claim
1. An integrated valve set for use in a vacuum toilet system having a waste receptacle defining an outlet and having a rinse fluid dispenser associated therewith, a source of rinse fluid, and a sewer line placeable under partial vacuum, the integrated valve set comprising:
- a discharge valve having an inlet in fluid communication with the waste receptacle outlet, an outlet in fluid communication with the sewer line, and a movable discharge valve member comprises a rotatable disk having a coupling member and adapted to selectively establish fluid communication between the discharge valve inlet and discharge valve outlet; and
a rinse fluid valve having an inlet in fluid communication with the rinse fluid source, an outlet in fluid communication with the rinse fluid dispenser, and a rinse fluid valve member adapted to selectively establish fluid communication between the rinse fluid valve inlet and rinse fluid valve outlet, the rinse fluid valve member being coupled to the coupling member for rotation with the discharge valve member.

Abstract
An integrated valve set for use in a vacuum toilet system is disclosed. The vacuum toilet system includes a waste receptacle defining an outlet and having a rinse fluid nozzle, a source of rinse fluid, and a sewer line placeable under partial vacuum pressure. The integrated valve set comprises a discharge valve having an inlet in fluid communication with the waste receptacle outlet, an outlet in fluid communication with the sewer line, and a rotatable discharge valve member adapted to selectively establish fluid communication between the discharge valve inlet and discharge valve outlet. An integrally mounted rinse fluid valve has an inlet in fluid communication with the pressurized rinse fluid source, an outlet in fluid communication with the rinse fluid nozzle, and a rinse fluid valve member adapted to selectively establish fluid communication between the rinse fluid valve inlet and the rinse fluid valve outlet. An integrally mounted actuator is adapted to rotate the discharge valve member and the rinse fluid valve member. An integrally mounted flush control unit has a circuit board operably connected to the actuator to selectively drive the actuator.
