Pressure-flushing cistern for a water closet

Abstract

The pressure-flushing cistern comprises a pressure tank ( 2 ), an actuating device for initiating a flush and also a pressure-reducing valve ( 27 ), which is to be connected to a water pipe and via which the pressure tank ( 2 ) can be filled with flushing water. The closing pressure of the pressure-reducing valve ( 27 ) is adjustable with a displaceable ring ( 17 ). The ring ( 17 ) can be gripped from outside through a window ( 19 ) of a housing ( 6 ) for adjusting the closing pressure. Adjustment preferably takes place by steps.
