Abstract: A flushing valve arrangement for controlling the flow of a pressurized flushing liquid includes a housing unit including an inlet and an outlet for the flushing liquid and a housing which bounds a flow passage that connects the inlet with the outlet. The housing is outwardly spaced from the outlet to bound therewith an annular channel which surrounds the outlet and opens into a communication region of the flow passage. A flushing valve unit is interposed in the flow passage downstream of the communication region and controls the flow of the flushing liquid from the inlet to the outlet. An externally actuatable shut-off valve unit is integrated into the arrangement and includes a shut-off sleeve surrounding the outlet and movable into and out of the annular channel toward and away from its closing position in which it extends into the communication region of the flow path and prevents the flushing liquid from flowing from the inlet toward the flushing valve unit.

Abstract: The valve piece of a toilet-tank discharge valve is moved into its open position by the release activation of an associated activating mechanism. It usually remains in this position until the flushing process is complete and the drops back into the closed position. The valve piece can also be moved back into its closed position ahead of time by discontinuance activation. The activating mechanism has a shift mechanism that can be reversed in its operating direction by a change of state in the toilet tank associated with release activation in such a way that discontinuance activation can result from renewed activation of one and the same activating mechanism in the same direction as during release activation. The device is convenient to operate and provides a wide range of possible ways of designing the operating element from the aspect of appearance. Simple remote operating devices can also be employed.

Abstract: A toilet-tank discharge valve has a main-valve body that can be lifted off of its face, by release-activating an auxiliary valve with an activating mechanism, as a consequence of negative water balance in an associated discharge compartment. A supplementary auxiliary valve is associated with the discharge compartment and opens at least briefly as a result of discontinuance activation of the activating mechanism, producing a positive water balance in the discharge compartment until the main-valve body closes. A valve of this type, with an auxiliary valve, makes it possible to discontinue the flushing process ahead of time. A shift mechanism in the connection between the activating mechanism and the supplementary auxiliary valve shifts the supplementary auxiliary valve from whatever limiting position it happens to be in into the opposite limiting position in response to a discontinuance activation.
