    • An induction assembly (100) for a high efficiency air filter includes a primary intake plenum (102), a primary throat aperture (106), a secondary intake plenum (112), a momentum transfer section (114), a static regain section (116), and a discharge opening (122). The primary intake plenum (102) directs primary air at high pressure to the primary throat aperture (106), which constricts the flow of the primary air and consequently increases the primary air velocity. The primary throat aperture (106) directs the high velocity primary air into the momentum transfer section (114), thus creating a negative pressure region by the Bernoulli principle and drawing a substantially equal quantity of the secondary air into the momentum transfer section (114). After the primary and secondary gasses mix in the momentum transfer section (114), the gas mixture continues on into the static regain section (116). As the gas mixture passes through the static regain section (116), the velocity pressure of the gas mixture is converted into static pressure, which is sufficient to force the gas mixture through a resistance at the discharge opening (122) such as an output filter (126).
    • 用于高效空气过滤器的感应组件(100)包括初级进气室(102),初级喉口(106),二级进气增压室(112),动量传递段(114),静态回流段 116)和排出口(122)。 初级进气增压室(102)将高压下的一次空气引导到主喉管孔(106),这限制了一次空气的流动,从而增加了一次空气速度。 主喉管孔(106)将高速一次空气引导到动量传递部分(114)中,由此通过伯努利原理产生负压区域,并将大致相等数量的二次空气吸入动量传递部分(114) 。 在主动和二次气体混合在动量传递部分(114)中之后,气体混合物继续进入静止回收部分(116)。 当气体混合物通过静态回收部分(116)时,气体混合物的速度压力被转换成静压力,其足以迫使气体混合物通过排出口(122)处的阻力,例如输出过滤器 (126)。

    • A compact air handling system includes an inlet channel which defines an inlet flow path in a first direction along a flow axis and a discharge channel which defines a discharge flow path in a second direction, opposite to the first direction along the flow axis. Air enters the air handling system through an inlet port and is discharged via a discharge port. The inlet channel is provided with acoustical buffering to attenuate inlet noise. The discharge channel is also provided with acoustical buffering in the form of a discharge silencer to attenuate noise in the discharge channel. The discharge silencer is disposed between the inlet channel and the discharge channel. An acoustical inlet plenum couples the inlet channel to the discharge channel. The cross-sectional area of the discharge channel adjacent the discharge port is larger than the cross-sectional area of the discharge channel adjacent the acoustical inlet plenum. If the inlet ports are not substantially equally distributed about the air handling system a transfer passage can be provided between the inlet ports and the inlet channel to provide equalization of the air flow.
    • 紧凑的空气处理系统包括:入口通道,其限定沿着流动轴线的第一方向的入口流动路径;以及排出通道,其限定沿着沿着流动轴线的与第一方向相反的第二方向的排出流动路径。 空气通过入口进入空气处理系统,并通过排放口排出。 入口通道提供声学缓冲以减少入口噪声。 放电通道还设置有放电消声器形式的声学缓冲器,以减弱放电通道中的噪声。 排放消声器设置在入口通道和排放通道之间。 声学入口增压室将入口通道连接到排放通道。 与排放口相邻的排出通道的横截面面积大于邻近声吸入室的排放通道的横截面面积。 如果入口端口基本上不分布在空气处理系统周围,则可以在入口和入口通道之间提供输送通道,以提供气流的均衡。
