Embodiment Construction

[0021] Reference will now be made in detail to the examples shown in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Directional designations such as "left" and "right" are for ease of reference to the drawings.

[0022] figure 1 is a view of the import panel without the perforated panel. The inlet panel 1 has a recess 2 surrounded by side walls 3 . The side wall 3 has an edge 4 . Between the edge 4 and the rear wall 5 is a step 6 . The depth and dimensions of the dimples 2 can be chosen to damp certain frequencies. figure 1 The example in shows the second part 7 of the inlet panel 1 . exist figure 1 Here, the second part 7 is the inlet panel 1 without perforated or porous material. Such as figure 2 and image 3 As shown, a perforated material such as the first part 8 , a porous material such as the porous material 9 , or both may be attached to the second part 7 to for...

Abstract

An inlet panel for a supercharger comprises a first portion, the first portion comprising one of a perforated material, a micro-perforated material, and a mesh layer. The inlet panel also comprises a second portion, the second portion comprising a recess and an axis. The recess is bordered in part by a side wall and a back wall. The first portion is offset from the back wall in the axial direction. The side wall has an edge located a distance away from the back wall in the axial direction.

Description

technical field [0001] The present application relates to a supercharger including an inlet panel with air pulsation damping. Background technique [0002] Air pulsations are a major source of noise for air moving devices in engine intake systems such as superchargers. Reactive acoustic elements such as Helmholtz resonators have been used in vehicle air intake systems to damp low frequency narrowband noise. However, reactive acoustic elements have limited application in vehicle air intake systems due to their potentially large size, requiring considerable volume. Dissipative elements like foam or fiberglass can be utilized, however, they are only effective for high frequency noise. Foam and fiberglass were also eliminated due to their potential to pollute the airflow, potentially damage the supercharger or engine, in addition to degrading performance. Contents of the invention [0003] The device disclosed herein overcomes the aforementioned shortcomings and improves on...
