    摘要: A three-lobe Root's blower is provided with feed back structure to bring the gas trapped in the impeller well volumes up to the discharge pressure prior to delivery. An essentially uniform and pulse-free discharge is produced by having a constant feed back flow rate which is achieved by always having a trapped impeller well volume in communication with the outlet via feed back structure which is sized to yield a continuous feed back flow rate.

    摘要: A two-rotor, sliding vane rotary compressor for compressing fluid containing an inner rotor, an outer rotor, means for rotating said inner rotor and said outer rotor at the same angular velocity, and at least one sliding vane disposed between the inner rotor and said outer rotor. The outer rotor is has an inner surface which is has at least one flat portion. As the inner rotor rotates, the sliding vane contacts the outer rotor.
