US Patent 7171701 Pressure-flushing device

The pressure-flushing device comprises a pressure vessel (2), which, for receiving flushing water, has a pressure chamber (D). The pressure chamber (D) can be filled with flushing water by means of an inlet valve (7). The pressure chamber (D) consists of cylindrical pressure chamber regions (D1, D2, D3) which are interconnected in a lower region of the pressure vessel (2). The pressure chamber regions (D1, D2, D3) are preferably formed by cylindrical walls (Z1, Z2, Z3), these walls being essentially circular in horizontal section. The pressure vessel (2) can be made from plastic and is both pressure-stable and compact.
