  "textContent": "A pressure-equalizing device for a housing with a lower part that has a fastening region for fastening to the housing and a connecting region; and an upper part which has a wall and a base, the upper part engaging the connecting region at an end of the lower part. The lower part has a projection defining an opening and having a clamping structure on a side that faces toward the end and also having multiple passages arranged in a ring shape between the opening and the clamping structure. The upper part has a second clamping structure. A membrane covers the opening, and a seal is arranged between the clamping structures and extends with a sealing region radially inward of the opening and seals the passages. A first path runs via the opening and the membrane, and a second path runs via the passages and the resilient seal component.",
