Claims (4)
- 空気圧急上昇を補償するための真空掃除機(1)用の装置(2)であって、前記装置を通って、第1の空気流(LS1)は第1の流れ方向(HS)に流れることができ且つ第2の空気流(LS2)は第2の流れ方向(NS)に流れることができ、
本体(13)は、第1の流れ断面積(A)と少なくとも1つの流れ抵抗要素(14、114)とを有し、前記流れ抵抗要素(14、114)の自由端部(14a、114a)は、少なくとも一部のセクション又は複数のセクションにおいて、第2の流れ断面積(B)を生成するために、本体(13)から前記第2の流れ方向(NS)に突出し、前記第1の流れ断面積(A)は前記第2の流れ断面積(B)よりも大きく、その結果、第2の流れ方向(NS)に流れる第2の空気流(LS2)が低減されることを特徴とする、装置(2)。 - 前記本体(13)は、シリンダの形態で構成され、且つ前記少なくとも1つの流れ抵抗要素(14、114)は、漏斗の形態で構成され、その結果、少なくとも一部のセクション又は複数のセクションにおいて、前記第2の空気流(LS2)の少なくとも一部に対する滞留容積(SV)が、前記流れ抵抗要素(14、114)の外側面(18)と前記本体(13)の内側面(16)との間に形成されることを特徴とする、請求項1に記載の装置(2)。
- 請求項1又は2の少なくとも一項に記載の装置(2)を有する真空掃除機ホース(11)。
- 請求項1又は2の少なくとも一項に記載の装置(2)を有する真空掃除機(1)。
