ABSTRACT:
A torque converter has a turbine and a pump with elastomeric linings on its core and shell surfaces proximate to the blades. The elastomeric linings are deformed where the blades engage the core and shell surfaces. This localized deformation effects a seal between the blades and the core and shell surfaces. This seal eliminates leakage between the blades and the cores and the shells, thereby increasing torque converter efficiency.
