Fresh water dosing device for steam ovens has vol. buffer with dosing chamber with defined storage vol. for fresh water in fresh water flow path between inlet and outlet valves

摘要

The device has a vol. buffer (12) with a dosing chamber (54) with a defined storage vol. for fresh water in a fresh water flow path between an inlet valve (8) and an outlet valve (10). The buffer and valves form a closed liquid system so that with the outlet valve closed fresh water under pressure can be enclosed in the dosing chamber and with the inlet valve closed the fresh water can be forced (24,42,60) out of the chamber via the opened outlet valve.
