  • Roots type gear compressor with helical lobes having communication with discharge port
    Patent number: 8419399
    Abstract: A gear compressor or supercharger for compressing compressible fluids such as air, having a pair of intermeshing helical lobed rotors. An aperture is provided on the bottom of the compressor, at a rear end thereof, which permits air from the rear interior of the compressor to be in communication with high pressure supply air which is discharged from such compressor proximate the front of such compressor, on the bottom underside portion thereof. The above modification improves the efficiency of the compressor, particularly at high revolutions.
    Type: Grant
    Filed: October 28, 2009
    Date of Patent: April 16, 2013

  • Roots type gear compressor with helical lobes having feedback cavity
    Patent number: 8096797
    Abstract: A gear compressor or supercharger for compressing compressible fluids such as air, having a pair of intermeshing helical lobed rotors. A plenum or cavity is provided at a rear end of the gear compressor, situated rearwardly of said rotors and below an respective axis of rotation of each of said rotors, which spans at least a distance between said respective longitudinal axis of rotation of each of said rotors. In a preferred embodiment the plenum is in direct fluid communication with high pressure fluid which is discharged from said high pressure discharge port. The above modification improves the efficiency of the compressor, particularly at high revolutions.
