発明の名称 (英語) FLUID MACHINE
発明の概要(英語) Provided is a rotary-type fluid machine, which can be run practically and effectively in an extremely low specific speed range. The rotary-type fluid machine (1, 1') comprises an impeller (10, 10') connected integrally to a rotating drive shaft (2). The impeller is housed in a casing (3). A forced feed fluid (a) in a suction passage (4) flows into the center portion (11) of the impeller. The fluid (b), which flows out from the outer circumference portion (12) of the impeller with the action of the centrifugal force of the rotating impeller, is discharged from a discharge passage (5) to the outside of the casing. Many grooves (15), which extend from the central portion of the impeller toward the outer circumference edge of the impeller, are formed in the impeller. The grooves are opened in the outer circumference (18) of the impeller, thereby to establish intense recirculation voltexes (R) near the outer edge of the impeller when the impeller rotates.
