Abstract
A screw rotor device has a housing with an inlet port and an outlet port and at least one pair of rotors. The rotors each have an identical number of threads (N), a buttress thread profile with a diagonal line, and a length that is either approximately equal to or less than a single pitch of the threads. The threads of the rotors intermesh as the rotors counter-rotate with respect to each other. The rotors can be twins or each one of the rotors can have different profiles.
