ABSTRACT:
A splitter-type impeller comprises a rotary disc member having a central hole to which a hub is fitted with a rotation shaft, a plurality of full blades disposed on one surface of the disc member, each of the full blades having a front edge portion positioned near an outer peripheral portion of the hub, a rear edge portion positioned near an outer peripheral portion of the disc member and a protruded intermediate portion so as to provide a curved shape, and a plurality of splitter blades disposed on the one surface of the disc member, each of the splitter blades having a front edge portion positioned backward of the front edge portion of the full blade in an axial direction of the disc member, a rear edge portion positioned near the outer peripheral portion of the disc member and a protruded intermediate portion so as to provide a curved shape in parallel to the full blade. The splitter blades and the full blades are alternately arranged with equal spaces along a rotating direction of the disc member, and each of the splitter blade has an extension blade formed integrally with the protruded intermediate portion of the splitter blade in a rectangular shape having an edge portion inclining from a corner portion of the protruded intermediate portion near the front edge portion of the splitter blade to a portion near the outer peripheral portion of the hub.
