Abstract
A manual override device for a flush assembly includes an override valve, an override chamber, and at least one input device. The override chamber includes a first fluid connection to a first side of a piston in a flush valve assembly and a second fluid connection to a second side of the piston in the flush valve assembly. The input device is coupled to the override valve and configured to initiate evacuation of fluid from the first side of the piston when the input device is actuated to begin a flush cycle in the flush valve assembly by way of movement of the piston.
Claims19
A manual override device for a flush assembly, the manual override device comprising:
- an override valve;
- an override chamber including a first fluid connection to a first side of a piston in a flush valve assembly and a second fluid connection to a second side of the piston in the flush valve assembly;
- an input device coupled to the override valve configured to initiate evacuation of fluid from the first side of the piston when the input device is actuated to begin a single flush cycle in the flush valve assembly by way of movement of the piston-;
- and
- wherein water bleeds to the piston in response to the input device and the single flush cycle automatically ends after the override chamber is substantially full so that only the single flush cycle is provided.
A flush valve system comprising:
- a valve assembly comprising:
- a piston;
- and
- a solenoid configured to cause the piston to move to an open position or a closed position;
- a manual override device comprising:
- an override valve;
- an override chamber including a first fluid connection to a first side of a piston in a flush valve assembly and a second connection to a second side of the piston in the flush valve assembly;
- an input device configured to initiate evacuation of fluid from the first side of the piston when the input device is actuated to begin a single flush cycle in the flush valve assembly by way of movement of the piston;
- and
- wherein water bleeds to the piston in response to the input device and the single flush cycle automatically ends after the override chamber is substantially full so that only the single flush cycle is provided.
