Patent ID: 8302604

Claim:
A cockpit oxygen mask comprising: a mask body ( 2 ), an oxygen inhalation valve ( 4 ), a mixed air inhalation valve ( 30 ), an exhalation valve ( 32 ) and a control device ( 26 ); wherein at least the oxygen inhalation valve ( 4 ) is signal-connected to the control device ( 26 ), wherein the oxygen inhalation valve ( 4 ) is designed as an electromagnetically actuatable valve with at least one through flow path ( 14 ) which may be closed by a magnetically movable valve body ( 22 ), wherein the through flow path ( 14 ) is limited by a magnetizable wall ( 16 ) and wherein the magnetizable wall ( 16 ) comprises at least one discontinuous location, which deforms a magnetic field produced in the magnetizable wall ( 16 ) to move the valve body and open the through flow path when the magnetizable wall is subjected to current, the oxygen inhalation valve fluidically coupled to the exhalation valve by an overflow channel and configured such that fluid pressure prevailing at an entry side of the through flow path of the oxygen inhalation valve presses the valve body against a valve seat when the through flow path is not magnetized and in this manner closes the through flow path, the overflow channel connects an exit side of the through flow path of the oxygen inhalation valve to a valve part of the exhalation valve, in a manner such that when the oxygen inhalation valve is opened the exhalation valve is impinged from opening by pressure applied to the valve part and a membrane of the exhalation valve in a closing manner, the overflow channel connected to the through flow path between the movable valve body and a movable valve disk of the oxygen inhalation valve, the oxygen inhalation valve comprises two exits, wherein a first exit runs into the mask body proximate the valve disk, and a second exit is conductingly connected via an overflow channel to the exhalation valve.
