ABSTRACT:
A respirator, comprising a number of controllers which are connected to a common duct and which serve to conduct different gases. Each controller comprises a gas passage provided with a displaceable closing member; a control member controls the position of the closing member, so that a predetermined gas flow occurs through the controller. To this end, the position of the closing member and the differential pressure across the passage are measured.
