Pressure food cooking apparatus, has stopper unit, and control unit comprising solid actuating unit, which is housed in sealed confinement zone that isolates solid actuating unit from gaseous flow coming from tight enclosure

摘要

The apparatus (1) has a stopper unit (7) co-operating with a drain port (5) of a purging unit (4) for permitting the purging unit to take opening and closing configurations. A control unit (10) passes the purging unit from its opening configuration to its closing configuration when temperature or pressure reigning in a tight enclosure (3) rises beyond a predetermined triggering threshold. The control unit comprises a solid actuating unit (11), which is housed in a sealed confinement zone (12) that isolates the solid actuating unit from a gaseous flow (F) coming from the enclosure.
