  • Patent number: 10480534
    Abstract: A supercharger outlet resonator comprises a housing, a first surface comprising a first opening and a housing axis bisecting the first opening, and a second surface comprising a second opening, the second surface located parallel to the first surface. A channel is perpendicular to the housing axis and connects the first opening to the second opening. The channel comprises at least one sidewall. An envelope is fluidly separated from the channel by the at least one sidewall, the envelope at least partially surrounds the channel, and the envelope extends from the first surface to the second surface. The envelope comprises a third opening and at least one second sidewall. A noise-reducing material located on the housing.

  • Publication number: 20170175818
    Abstract: A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger constructed in accordance to one example of the present disclosure includes a coupling hub and a plurality of pins. The coupling hub can have a series of lobes. Adjacent lobes of the series of lobes can define a plurality of openings. The coupling hub can further define a mounting bore therein. The plurality of pins can have first ends and second ends. The first ends can be correspondingly received by the plurality of openings. The second ends can be received by the rotor shaft. The input shaft can be directly mounted into the mounting bore of the coupling hub for concurrent rotation therewith.

  • Patent number: 8770176
    Abstract: A valve assembly includes a housing defining first, second, third, and fourth passages. The first passage channels relatively-high pressure fluid and the second passage channels relatively-low pressure fluid into the valve. The third passage connects to the second passage and releases fluid from the valve. The fourth passage connects to the first passage and the second passage and releases fluid from the valve. The valve assembly also includes a first check-valve that permits fluid flow from the second passage to the third passage and a second check-valve that permits fluid flow from the second passage to the fourth passage. The valve assembly additionally includes a nozzle that controls velocity of the relatively-high pressure fluid entering the fourth passage from the first passage. The relatively-low pressure fluid is pulled from the second passage into the fourth passage on the outer periphery of the nozzle by the relatively-high pressure fluid.

  • Publication number: 20110153159
    Abstract: A power steering system for a motor vehicle includes a rack and pinion assembly in which the teeth of the pinion are engaged with the teeth of the rack. The power steering system further includes magnets (e.g., permanent magnets or electromagnets) connected to the rack, as well as magnets (e.g., permanent magnets or electromagnets) connected to a rack tube. A varying maglev (i.e., magnetic levitation) force obtained by controlling current flowing through at least some of the magnets (e.g., by varying duty cycle of pulse-width-modulation through an electronic control unit) provides steering assistance for the motor vehicle employing the power steering system. A power steering system includes first and second steering elements, magnets connected to the steering elements, and a controller configured to obtain speed information and steering position information and to control the activation of the magnets in response to the speed information and steering position information.
