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.

The invention claimed is: 1. A flushing device for a lavatory, comprising a flushing cistern in which is arranged at least one pressure vessel, the pressure vessel having a feed line for water and a discharge valve, wherein at least some of flushing water is subjected to pressure and is discharged through the discharge valve for flushing purposes, and at least one pressure-cylinder unit has the flushing water subjected to pressure and discharged by way of a spring-force-loaded pressure piston for flushing purposes, the piston has an upper starting and lower position, wherein the pressure piston is locked in the upper starting position and is unlocked for flushing purposes. 2. The device as claimed in claim 1, wherein the pressure-cylinder unit subjects all the flushing water to pressure. 3. The device as claimed in claim 1, wherein the pressure-cylinder unit is formed, at least in certain regions, by an outer wall of a flushing-cistern body. 4. The device as claimed in claim 1, wherein the pressure-cylinder unit has, in a base, a through-passage opening, the through-passage opening opens out into a chamber including the discharge valve. 5. The device as claimed in claim 1, wherein the discharge valve is a servovalve. 6. The device as claimed in claim 5, wherein the discharge valve has a flexible diaphragm, the diaphragm closes the discharge valve under water pressure. 7. The device as claimed in claim 6, wherein the diaphragm is designed as a folding bellows. 8. The device as claimed in claim 5, wherein the discharge valve is triggered by actuation of an air-extraction member. 9. The device as claimed in claim 1, further including an inflow valve connected to a supply line and opening automatically in an event of a drop in pressure. 10. The device as claimed in claim 9, wherein the inflow valve is assigned a pressure-regulating valve, the pressure-regulating valve closes the inflow valve automatically in a case of a predetermined system pressure. 11. The device as claimed in claim 1, wherein the discharge valve opens out into a horizontally extending discharge connector. 12. The device as claimed in claim 1, wherein the discharge valve has a through-passage connecting an inner chamber to an outer chamber, and during a refilling operation, water is introduced through the through-passage into the outer chamber and into at least one pressure chamber. 13. The device as claimed in claim 1, further including two pressure-cylinder units actuated independently of one another. 14. The device as claimed in claim 13, wherein an actuating means optionally triggers partial flushing or full flushing, where one pressure-cylinder unit is actuated in a case of partial flushing. 15. A flushing device for a lavatory, comprising a flushing cistern in which is arranged at least one pressure vessel, the pressure vessel having a feed line for water and a discharge valve, wherein at least some of flushing water is subjected to pressure and is discharged through the discharge valve for flushing purposes, and at least one pressure-cylinder unit has the flushing water subjected to pressure and discharged by way of a spring-force-loaded pressure piston for flushing purposes, wherein the discharge valve is a servovalve, wherein the discharge valve is triggered by actuation of an air-extraction member, and wherein air is extracted via a channel, the channel opens out into a discharge connector of the flushing cistern.
