Zusammenfassung:A leakage gas valve 15 ventilation apparatus comprising a first valve body 16 having a main gas path chamber 17 for guiding an inhalation gas to a patient, comprising at least first, second and third chamber sections 18, 19, 20, an inlet duct 21 for supplying the ventilation gas to the first chamber section 18, an outlet duct 22 for releasing the ventilation gas from the third chamber section 20. The first chamber section 18 and third chamber section 20 comprise a first cross-section area (A1) and the second chamber section 19 comprises a second cross-section area (A2). The second cross-section area (A2) is smaller than the first cross-section area (A1), and the second chamber section 19 comprises a leakage channel 25 for allowing a leakage gas flow out of the gas valve 15 during exhalation. Additionally, circuits with a ventilation limb comprising a gas valve.
