Embodiment Construction

[0032] According to the principles of the present invention, a Roots-type supercharger includes at least one bleed port, which can be used to reduce the noise generated by the Roots-type supercharger. Three exemplary embodiments are shown in the drawings. Figure 1-14 The illustrated Roots-type supercharger 100 includes at least one bleed port 600 that may be used to reduce noise generated by the Roots-type supercharger 100 . The support plate 160' of a Roots-type supercharger similar to the Roots-type supercharger 100 includes at least one drain port 600', which can be used to reduce the noise generated by the Roots-type supercharger, and in Figure 15 and 16 shown in . Figure 17-22 The illustrated Roots-type supercharger 1100 includes at least one bleed port 1600 that may be used to reduce noise generated by the Roots-type supercharger 1100 . In particular, the embodiments depicted in the figures include a pair of bleed ports 600 , 600 ′, 1600 . As shown, the Roots boos...

Abstract

A Roots-type supercharger includes a housing, a first rotor, a second rotor, an outlet volume, a transfer volume, and a bleed port. The housing includes an interior chamber, an inlet port, and an outlet port. The first rotor and the second rotor have a plurality of lobes respectively. The outlet volume is substantially bounded between the outlet port, the first rotor, the second rotor, and the interior chamber of the housing. The transfer volume is substantially bounded between the first rotor, the second rotor, and the interior chamber of the housing. The bleed port is adapted to fluidly connect the outlet volume and the transfer volume at least during a portion of a transfer volume cycle. The variable bleed port may include a plate that pivots about a pivot or slides along a slide. The plate may be arc shaped and may arc around a centerline of one of the rotors. The plate may be positioned within an operating cavity. The operating cavity may be defined within the housing between a bearing plate and a main housing of the housing. A method of supercharging an internal combustion engine includes bleeding a transfer volume to an outlet volume through a bleed port.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 61 / 794,817, filed March 15, 2013, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a Roots type supercharger. More specifically, the present invention relates to noise reduction and active regulation of Roots-type superchargers. Background technique [0004] A supercharger increases the performance of an internal combustion engine. For medium to high speeds with no or low boost, a Roots-type supercharger develops a high-pressure zone within each rotor transfer volume opposite the inlet. When this transport volume is open to the outlet, this high pressure zone may generate undesired noise levels at the outlet. Such noise is generally an undesired effect of a Roots-type supercharger under these conditions. Contents of the invention [0005] According to certain a...
