FIELD: transport.
SUBSTANCE: invention relates to aircraft and space engineering and can be used in designing flight vehicle compartments. Proposed compartment comprises enclosure with vent hole, spring-loaded cover pivoted in aforesaid vent hole of enclosure. Aforesaid cover also has vent hole accommodating pivoted spring-loaded panel arranged flush with cover surface. Compartment enclosure incorporates cover motion retainer, while cover and panel are furnished with retainers to limit motion of the panel outside enclosure to allow cover to move with panel outside, and, separately, and limit panel motion into compartment.
EFFECT: control of pressure differential in compartment in ascent and descent, simpler design and expanded performances.
