    摘要: Die vorliegende Erfindung betrifft einen Resonator (1) zur Behandlung von Luftschall, der sich in einer gasführenden Leitung (5) ausbreitet. Der Resonator (1) besitzt einen Resonatorhals (9), der die Leitung (5) mit einem Resonatorvolumen (6) kommunizierend verbindet.
    Um den Resonator (1) an schwierige Einbausituationen anpassen zu können, weist der Resonatorhals (9) entlang seiner Längsrichtung (11) eine konstante Innenquerschnittsfläche und eine variierende Innenquerschnittsgeometrie auf.

    摘要: An air cleaner includes a slide retention structure which engages a sliding resonator volume. The volume slides along the slide retention structure into an assembled position. Once assembled, a tuning tube engages an aperture in the volume, the volume and the resonator assembly reducing noise produced by the engine. A flexible seal is positioned around the aperture to acoustically seal the resonator volume to the tuning tube. An air cleaner cover is secured to the box by a lock plate. To lock the cover to the box, the lock plate is slid so that a plurality of wedges on the plate are forced under hooks on the box, securing the cover to the box. A side opening located proximate to the wedges allow the lock plate to slide so that the hooks do not hinder the movement of the lock plate.

    摘要: An air resonator system for a vehicle has a variable volume to reduce noise expected at both high and low speeds. In one embodiment, a pair of necks (28, 32) communicate with chamber portions (30, 31). A valve (38) selectively blocks communication between the chamber portions (30, 31) and allows each of the necks to communicate with the relatively small volume chamber portions. This position is particularly good for reducing the high frequency noise expected at high engine speeds. The valve (38) is movable to a second position at which it allows communication between the two chamber portions and blocks communication between one of the necks and its respective chamber portion. The relatively large chamber volume provided at this position is particularly well suited for reducing the low frequency noise expected with low engine speed. Thus, a single air resonator system is provided which can be adjusted to accommodate noise at both high and low speeds.
