Abstract:
1. A resonator for an induction system comprising: a resonator body including a resonator cavity and an inlet and an outlet; a tube extending at least partially between the inlet and the outlet, the tube generally separating the resonator cavity into large and small cavity portions, the tube including an opening facing the large cavity portion in communication with the resonator cavity, wherein the tube includes an open end supported by one of the inlet and the outlet, and an opposing open end opposite the end, the opposing open end spaced from and aligned with the other of the inlet and the outlet to provide a gap, the inlet and outlet in fluid communication with one another through the open ends of the tube, wherein the gap fluidly connects the large and small cavity portions; and a collar supported by the resonator body and supported concentrically relative to at least one of the inlet and the outlet, the collar and the at least one inlet and outlet providing an annular cavity configured to provide noise attenuation.
