Abstract
A beverage maker has a valve structure () adapted block the return of water from a boiler () to its water reservoir () in response to a water pressure from the boiler exceeding a shut-off pressure value. The valve structure () further includes a discharge outlet () connected for water outflow to the brewing unit () and is adapted to open a passage from that inlet () to the discharge outlet () in response to a water pressure at the inlet () exceeding a discharge pressure value below the pumping pressure. The valve structure () is further adapted to block the return of water from the boiler () to the water reservoir () also in response to a water pressure from the boiler below a relief pressure value above atmospheric pressure and below the shut-off pressure value. The pressure in the boiler during heating towards boiling is thus kept above atmospheric pressure.
