Description
Technical field
The present invention relates to a kind of sound arrester, especially relate to a kind of sound arrester being provided with resonator cavity.
Background technology
Acoustic energy is produced by suction line when fresh air is inhaled in oil engine. The air passing through to supply causes vibration in suction line, and this causes undesirably sounds. The various dissimilar resonator of known use, such as conspicuous nurse Hertz resonator, to reduce the air suction and noise of oil engine. By making, the suction air resonance of the air in resonator and vibration reduces vibration to resonator.
DE60017075T2 discloses a kind of resonator. This kind of resonator is formed primarily of housing, and the resonator cavity of big volume is closed by housing. Resonator cavity is connected by the suction line of airline with the inlet system of car combustion engine. By this airline, the resonant wave of air communication in the part volumetric flow rate of suction line and resonator cavity owing to producing, vibration in suction line is reduced, and this causes the shortcoming sending the known resonator of less noise this kind to be that the resonator cavity of big volume takies big quantity space.
US5756945A discloses the resonator of a kind of noise produced in the suction line of car combustion engine for reducing. The resonator of the disclosure is characterised in that, whole volumetric flow rates of suction line all import in the resonator cavity of resonator. Be provided with the first airline from air filter for this reason, this first airline import in housing by inlet mouth and opening terminate in resonator cavity. And the confluence area of the 2nd airline it is provided with to this first airline interval in intra resonant cavity. It is that resonator takies big quantity space equally that 2nd airline is directly stretched to the shortcoming of resonator disclosed in this kind of oil engine by the air vout in housing.
It thus is seen that at present, traditional resonator cavity cannot realize only two parts and realize sharing of resonator cavity when different engine shares main pipeline. Adopt traditional structure so that pipeline structure is very complicated and part number can increase greatly.

The contact part of main pipeline and upper cover is provided with longitudinal direction and grows one or more in pipe, noise reduction hole, partition or longitudinal short tube.
Described upper cover upper end cavity is welded to connect with main pipeline, block to establish and be connected or achieve a fixed connection through sealing-ring.
The lower end cavity of described upper cover be welded to connect with main pipeline or block establish connecting welding to be connected, block establish connect or achieve a fixed connection through sealing-ring.
Described upper cover upper end cavity through longitudinally cut off and main pipeline is divided in quarter wave pipe chamber, multi-hole resonant cavity, conspicuous nurse hertz resonator cavity or multi-hole resonant cavity one or more.
Described quarter wave pipe chamber is the part surrounded between the long pipe of longitudinal direction and upper cover upper end cavity arranged on main pipeline, and described conspicuous nurse hertz resonator cavity is the part surrounded between longitudinal short tube and upper cover upper end cavity.
Described upper cover lower end cavity through longitudinally cut off and main pipeline is divided in quarter wave pipe chamber, multi-hole resonant cavity, conspicuous nurse hertz resonator cavity or multi-hole resonant cavity one or more.
Described quarter wave pipe chamber is the part surrounded between the top of the long pipe of longitudinal direction arranged on main pipeline and the lower end cavity of upper cover, and described conspicuous nurse hertz resonator cavity is the part surrounded between the top of longitudinal short tube and the lower end cavity of upper cover.
Compared with prior art, the present invention forms the completely different noise-abatement equipment of two kinds of functions by the combination of main pipeline and upper cover upper end cavity or upper cover lower end cavity, it is thus possible to be used in the different engine type of same platform, noise elimination function requires in different dollies, reach the object of seriation, specifically comprise following advantage:
(1) part number is few, only main pipeline and upper cover two parts;
(2) can forming multiple noise elimination resonator cavity: multi-hole resonant cavity, conspicuous nurse hertz resonator cavity, and quarter wave pipe, the range of frequency that can eliminate the noise is very wide;
(3) by the upper and lower ends of upper cover, the noise elimination resonator cavity of two kinds of not congenerous can be formed, arrive the function of seriation.
