Filter element flow parts device, the filter element, a filter system with a filter element, as well as a method for providing a filter element flow parts device and / or of a filter system and / or of a filter element

摘要

The invention relates to a filter element flow parts device (50) for generating a predetermined flow profile in a downstream media flow of a filter element, comprising a pure air chamber section (70), an exhaust channel section (72) with an exhaust channel cross-section (74), and optionally with a seal (22) for sealing of the exit flow duct (72), and a mass flow sensor (120), comprising at least one guide vane wall portion (52, 54) with an inflow curvature region (76), which is in particular, and preferably continuously, with an outlet passage wall portion (78) is connected, and wherein the guide vane wall portion (52, 54) in the longitudinal section in a predetermined flow direction plane (26) from the pure air chamber section (70) for a mass sensor (120) of an angle of attack (a) a tangent (88) to the maximum curvature point of the inflow curvature region (76) in relation to the flow direction plane (26) and / or with respect to at least one further guide blade wall section, wherein the guide vane wall portion (52, 54) in the air chamber section (70) is arranged on the outflow side and predetermined to the purely air chamber section (70) of the exhaust channel section (72), optionally with the seal (22), is arranged, and on the outlet side, to the purely air chamber section (70) and / or for a plurality of exhaust channel section (72) of the mass flow sensor (120) is arranged, whereby the mass flow sensor (120) directly behind the guide vane wall portion (52, 54) is arranged or in a distance (82) of up to once to the exhaust channel cross-section (74) of the exhaust channel section (72) to the outlet passage wall portion (78), in particular to the end of the outlet passage wall portion (78), is arranged at a distance, a filter system (100), and furthermore, the invention relates to a replaceable filter element, as well as a method for providing a filter element flow parts device (50) and / or of a filter system (100) and / or of a filter element.n="39"
