Abstract
An exhalation valve for a ventilator apparatus for at least partial instrumental respiratory assistance of a patient, includes a valve housing with a flow passage which extends along a passage trajectory defining a local axial, radial and circumferential direction and along which respiratory air can flow through the valve housing. The valve housing has a housing-side valve sub-formation with a closed end surface which extends around the passage trajectory and towards which a mating surface of a valve body, movable relative to the valve housing and facing the end surface, can be pretensioned by the pretensioning force of a pretensioning device in such a way that the mating surface, when subjected to respiratory gas in an exhalation flow direction counter to the pretensioning force of the pretensioning device, is removable.
