Claims (10)
- 空気吸込管(1)と該空気吸込管(1)内に半径方向で差し込まれた空気質量センサ装置(2)とを備えた装置であって、前記空気質量センサ装置(2)の流入開口(3)が、吸込管(1)内で空気流れ方向(6)に対して垂直に配向されており、流入開口(3)の手前に、翼状の遮蔽体(7)が、一方では流入開口(3)を覆い隠しかつ他方では流入開口(3)への剥離しない空気流れを保証するように配置されており、遮蔽体(7)の、その表面上を流れる空気の流れ方向に対して横方向に延びているほぼ直線的な表面が、空気質量センサ装置(2)の差込み方向に対して垂直に配向されていることを特徴とする、空気吸込管と該空気吸込管内に差し込まれた空気質量センサ装置とを備えた装置。
- 遮蔽体(7)が、その表面上を流れる空気の流れ方向で、反った経過を有している、請求項1記載の装置。
- 遮蔽体(7)の、実質的に吸込管(1)内を流れる空気の流れ方向(6)に延びている縁部が、側壁(13,14)を備えており、これらの側壁(13,14)が、遮蔽体(7)の上面および/または下面を、縁部渦動を回避するために側方で制限している、請求項1または2記載の装置。
- 遮蔽体(7)の、吸込管(1)内を流れる空気の流れ方向(6)に向かって配向された擦過縁部(8)が、斜め面取りまたは丸面取りされており、これにより、空気流れが良好に付着させられ得るようになっている、請求項1から3までのいずれか1項記載の装置。
- 遮蔽体(7)の、吸込管(1)内を流れる空気の流れ方向(6)に配向された縁部(12)が、空気質量センサ装置(2)の流入開口(3)の下方に、かつ空気流れ方向(6)に関して流入開口(3)の後方に位置する、請求項1から4までのいずれか1項記載の装置。
- 遮蔽体(7)が、吸込管(1)と一体的に形成されている、請求項1から5までのいずれか1項記載の装置。
- 遮蔽体(7)がその4つの角隅に保持部(9,10)を有しており、前方の保持部(9)と後方の保持部(10)とが、互いに側方でずらして配置されている、請求項1から6までのいずれか1項記載の装置。
- 後方の保持部(10)が、空気流れが吸込管中央に案内されるように、空気流れ方向(6)に対して斜めに配置されている、請求項1から7までのいずれか1項記載の装置。
- 前方の保持部(9)の後方縁部(11)が、空気流れ方向(6)に対して斜めに、吸込管壁に向かって延びている、請求項1から8までのいずれか1項記載の装置。
- 空気質量センサ装置(2)の空気擦過面に、横方向に延びているウェブまたは横方向細溝(15)が設けられている、請求項1から10までのいずれか1項記載の装置。
