Device for reducing a (partial -) pressure of at least one chemical species in a closed cavity, component and method for the production of the component

摘要

The present invention relates to a device (100) for reducing a (partial -) pressure (p) of at least one chemical species in a closed cavity (102). The apparatus (100) has a getter (106) and a heater (108) on. The getter (106) is designed, at least a portion of the species from the cavity (102) when the getter (106) within the cavity (102) to a temperature greater than a receptacle is heated. The heater (108) is in the form of a chemical heater (108) and thermally with the getter (106) coupled. The heater (108) is designed, by means of a self-sustaining exothermic reaction, the getter (106) via the receiving fixture temperature to heating, if the heater (108) is activated with an activation energy.
