A torque converter includes: a impeller having an outer shell, an inner core, and at least one pump blade provided between the outer shell and the inner core; a turbine having at least one turbine blade; and a stator capable of establishing a fluid circulation between the impeller and the turbine. An exit angle of the at least one pump blade is greater than -90 degrees up to -68 degrees at the most, beginning from a first point, at which the at least one pump blade is in contact with the outer shell, to a second point, at which the at least one pump blade is in contact with the inner core.
