Abstract: A flushing device comprising an evacuation fitting (6) that is provided with a sealing member (7) within a pressurized container (2). The sealing member (7) is lifted counter to the pressure of a piston (16) in order to initiate the flushing process. A connecting device (39) for a water pipe (24) is disposed on the container (2). The flushing device further comprises a structure (49, 50) for flushing with a partial quantity of the flushing water. For example, the structure (49, 50) is provided with a power-loaded part (50) which moves the valve member (7) down onto the valve seat (5) of the evacuation fitting (6) when the flushing process is interrupted. In an alternative embodiment, two chambers are provided, only one of which is emptied during partial flushing. Flushing water can be conserved by the fact that the flushing process can be interrupted.

Abstract: A flushing device includes a cistern, in which at least one pressure chamber is arranged with a supply line for water and a discharge valve. At least part of the flushing water may be pressurised in the pressure chamber and may be discharged for flushing through the discharge valve. At least one pressure cylinder unit is provided, in which the flushing water may be pressurised and discharged for flushing, by means of a spring-loaded pressure piston. The pressure piston is preferably held in a starting position and may be released for a flushing execution. Should two pressure cylinder units be provided, either a partial or a complete flushing operation may be selected.

Abstract: The flushing device has a flushing water tank with a closure, which is to be opened to trigger a flushing. The closure is arranged at water outlet openings of the toilet bowl. The toilet ring of the toilet bowl can thus accommodate part of the flushing water needed for the flushing. The flush tank proper can thus be made substantially smaller and flushing will be less noisy, because air noises are avoided during the flow of flushing water into the toilet ring.
