    • An air inlet system for an automotive HVAC system has a housing comprising a first cylindrical segment enclosing an interior space and having a first radial surface with a first angular divergence. The first radial surface has a fresh air aperture and a recirculation aperture for radially receiving fresh air and recirculated air, respectively. The housing further comprises an outlet body with an exit aperture. A pivoting door element is mounted in the interior space and shaped as a second cylindrical segment with a second radial surface with a second angular divergence which is less than the first angular divergence. The door element has a pivot axis that allows the second radial surface to slide along the first radial surface. The door element pivots to selectably align the opening with the fresh air aperture or the recirculation aperture in order to 1) block the fresh air aperture without blocking the recirculation aperture, 2) simultaneously block portions of the fresh air aperture and the recirculation aperture, 3) block the recirculation aperture without blocking any of the fresh air aperture, or 4) block the recirculation aperture while blocking only a portion of the fresh air aperture.
    • 用于汽车HVAC系统的空气入口系统具有壳体,该壳体包括封闭内部空间的第一圆柱形段,并且具有第一角度发散的第一径向表面。 第一径向表面具有新鲜空气孔和用于分别径向接收新鲜空气和再循环空气的再循环孔。 壳体还包括具有出口孔的出口主体。 枢转门元件安装在内部空间中并且被成形为具有小于第一角度发散的第二角度发散的第二径向表面的第二圆柱形段。 门元件具有允许第二径向表面沿着第一径向表面滑动的枢转轴线。 门元件枢转以可选择地将开口与新鲜空气孔或再循环孔对准,以便1)阻挡新鲜空气孔而不阻塞再循环孔,2)同时阻挡新鲜空气孔和再循环孔3的部分 )阻挡再循环孔而不堵塞任何新鲜空气孔,或4)堵塞再循环孔,同时阻挡新鲜空气孔的一部分。
