Abstract

The toilet cistern outlet valve has a servo valve, which after actuation allows the static pressure of the water column to automatically open the main valve. The sealing section of the main valve consists of a piston (2), moving up-and down. The outlet side of the piston carries a sealing flange (31), and its opposite surface faces a cylinder chamber (13). With an actuation of the servo valve (32), the chamber is relieved of the water pressure. The chamber area is pref. larger than that of the main valve seat (31). The servo valve is located in the piston and is self-holding.
