An air vent is installed in an outside wall and contains a screw thread on an inner surface of an inner end. An abutment is located inside the vent. A cap is shaped to screw into the vent and rests against the abutment when it is in a closed position. The cap and the abutment contain openings that permit air to flow through the vent when the cap is open and prevent air from flowing through the vent when the cap is closed. The cap can be partially open so that some air flows through the vent. The vent can be easily installed and maintained. It can be left open when the building is unoccupied, without any sacrifice in security.

Cette invention concerne un dispositif d'aération monté dans un mur extérieur et comportant un filetage intérieur du côté intérieur. Un épaulement est prévu dans le dispositif d'aération. Un capuchon à visser dans le dispositif prend appui contre l'épaulement lorsqu'il est en position fermée. Le capuchon et l'épaulement comportent des ouvertures permettant la circulation d'air à travers le dispositif lorsque le capuchon est ouvert, aucune circulation d'air n'étant possible lorsque le capuchon est fermé. Celui-ci peut être partiellement ouvert pour permettre une certaine circulation d'air. L'objet de l'invention est facile à installer et à entretenir. Il peut être laissé ouvert lorsque le bâtiment est inoccupé, sans compromettre la sécurité de celui-ci.
