Mueller, R S

This patent describes a rotary blower of the backflow type with a housing, inlet and outlet ports and a chamber defined by the housing. There exists first and second meshed lobed rotors located within the chamber for transferring volumes of low-pressure inlet port air to the high pressure outlet port air. A controlling mechanism for controlling the rate at which outlet port air backflows into the transfer volume is described. The control means is defined by first and second expanding orifices located on transversely opposite sides of the outlet port. These expanding orifices alternately operate at predetermined rotor speeds and pressure differential relationships to maintain a constant backflow into each of the transfer volumes.
