Abstract
A device (), for a ventilation system (), includes an inhalation valve () with an inhalation opening () for flow () of breathing gas () into a pressure chamber () to provide breathing gas in the pressure chamber for ventilating a patient (). A closing element () is arranged movably, to close the inhalation opening to flow in a closed position () and to at least partially release flow in an open position (). A transmission device () is connected via a connection element () to the closing element, to hold the closing element in the closed position in a starting position of the transmission device, such that the inhalation valve is normally closed. A control pressure source () provides a control pressure (PS) in a control pressure chamber () for the transmission device to move the transmission device out of the starting position by the control pressure.
