Abstract
A breathing gas system and water trap (1) is improved in respect to the reliability of operation and has an emptying device. The water trap (1) has a gas inlet (4), which meets a first water separating membrane (5) via a connection line. The connection line leads into a water tank (20) located deeper in the incoming flow direction from the first water separating membrane (5) and into a gas measuring device (2) with vacuum on the discharge side from the first water separating membrane (5) from the water trap (1). The water tank (20) has a rinsing gas flow line, which is arranged above the liquid level, leads upward via a gas-permeable membrane (6) and is likewise connected to the applied vacuum of the gas measuring device (2). The water tank (20) has a water transport line for emptying the water tank (20), which water transport line extends into the liquid and is provided with a downstream vacuum via a nonreturn valve (7) and a downstream liquid pump (17) or via a solenoid valve (21). The water trap (1) is equipped with a filling level detection system (8, 9, 22; 8, 9, 13; 8, 10), which is connected to a control and analyzing unit (3). The control and analyzing unit (3) is connected…
