Abstract (en)

[origin: WO9826830A1] The valve (14) comprises a housing (22) and a slider element (24) connected to a mask housing (26). During normal operation side ports (30, 34) are closed by element (24). The air flow to a patient must be sufficient to overcome the slight attractive force between magnets (36, 38). If the flow from the generator drops to below the level necessary to keep the slider element to the open position, the magnets move together allowing plate (39) to stop flow to the patient, who may breath unassisted through the side ports.
