Airlocks

Part of speech: noun

Definitions

1. A device that functions as a barrier to control the transfer of air between two contrasting environments while allowing safe passage An apparatus that ensures atmospheric integrity during transitions, commonly found in spacecraft and underwater vehicles A structure designed to maintain atmospheric conditions and safety by managing airflow when moving from one compartment to another
2. A specialized enclosure that permits safe entry or exit between two distinct atmospheres while preventing air leakage A crucial component in space and marine technology used to manage pressure differences and maintain breathable conditions A controlled access point that facilitates the movement of personnel or materials while keeping environmental integrity intact during transitions
3. A sealed chamber that regulates air pressure and prevents air exchange while allowing people or objects to move between areas with different atmospheres

Etymology: "Airlocks" is the plural of "airlock," a compound of "air" and "lock." The "lock" half comes from the older sense of a lock as an enclosed section of a canal, a chamber whose water level is raised or lowered so boats can pass between stretches at different heights. The airlock applies that same principle to air: a sealed compartment is pressurized or depressurized so people or equipment can move between spaces with different atmospheres without the two air supplies mixing. The word thus joins a familiar object with a very literal description of what it does. It is a plain, transparent compound, and its meaning follows directly from its parts: an "air" lock works on air as a canal lock works on water.

Synonyms: chambers, locks, seals, hatches, barriers
