A compressor design includes a male rotor () having one or more helical lobes () and a female rotor () having one or more helical grooves (). The male rotor is mounted on a first shaft and the female rotor is mounted on a second shaft. The male rotor is positioned in a first section of a chamber and the female rotor is positioned in a second section of the chamber. Fluid enters the chamber at an inlet, and when the rotors are driven, the lobes of the male rotor fit into the grooves of the female rotor, causing compression and movement of the fluid towards an outlet or discharge end where the compressed fluid is discharged. The configuration of the lobe and groove helix, the lobe and groove profile, and the outer diameter of the rotors can be varied in different combinations to form different rotors.

An assembly of a compressor for pressurizing a fluid includes a main housing having a portion being substantially planar. The housing defines at least two parallel intersecting bores. At least two rotors are journaled for rotation within the bores. A plurality of vent channels in the main housing extend outwardly from at least one bore through the portion being substantially planar. The vent channels are configured for the fluid to flow through the vent channels. A slide valve assembly is operably connected to the housing proximate the plurality of vent channels. The slide valve assembly has a valve plate wherein the valve plate has a substantially planar side that is sealingly engaged with the planar portion of the main housing. The valve plate is positioned into one of a plurality positions relative to the vent channels.
