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.
Claims15
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.
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.
