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.
