Abstract:
1. A gear compressor for compressing compressible fluids such as air, comprising: a housing defining first and second mutually adjacent, parallel, elongate overlapping cylindrical chambers, having a front end and a rear end and a low pressure inlet port and a high pressure discharge port thereon; a pair of juxtaposed rotors, each disposed in a respective of said cylindrical chambers and each oppositely rotatable , each having a plurality of radially outwardly extending lobes thereon equidistantly circumferentially spaced about a periphery of each rotor and intermeshed along a side thereof with lobes of an opposite rotor of said pair of rotors, each of said lobes on said rotors twisted about a respective longitudinal axis of rotation of each rotor in a helix angle, each helix angle of each of said lobes on a first of said pair of rotors being equal and opposite to said helix angle of each of said lobes on said other of said pair of rotors, said rotors within said respective cylindrical chambers each adapted to transfer volumes of compressible low pressure fluid from said low pressure inlet port via spaces created between walls of said respective cylinder chambers and unmeshed lobes of each rotor axially along said respective cylindrical chambers from said front end to said rear end of said gear compressor and then axially back along said gear compressor to a location proximate said front end of said gear compressor and thereafter to said high pressure discharge port; said high pressure discharge port situated on a bottom surface of said gear compressor proximate said front end thereof; said low pressure inlet port situated on a top surface of said gear compressor proximate said front end thereof; and divider means situated on a bottom surface of said gear compressor extending from said front end to said rear end of said gear compressor, a first aperture in said divider means proximate said front end which comprises said high pressure discharge port; and a second aperture situated proximate said rear end of said compressor proximate said bottom surface; said second aperture permitting fluid communication between an interior of said gear compressor at said rear end of said gear compressor and high pressure fluid discharged from said high pressure discharge port.
