Abstract
An impeller for a torque converter embodying the concepts of the present invention utilizes a substantially semi-toroidal shell. The shell has a radially inner periphery which defines an inlet portion and a radially outer periphery which defines an outlet portion. The shell is radially curved between the inlet portion and the outlet portion to define a concave annular recess. A plurality of full vanes and a plurality of splitter vanes are presented from the shell within the annular recess. The impeller vanes are disposed circumferentially about the concave recess at spaced intervals. Each vane has a leading head portion, an intermediate body portion and a trailing end portion. The leading head portions of both vanes are disposed in opposition to the inlet portion--the leading head portion of the full vanes being disposed in proximity to the inlet portion. The leading head portions of the splitter vanes are disposed in radially outwardly spaced relation to the inlet portion. The trailing end portions of both the full and the splitter vanes are disposed in proximity to the outlet portions. The leading head portions on both the full and the splitter vanes are bulbous with curvilinearl…
