ABSTRACT:
An apparatus, system, and method are disclosed for a single-actuated multi-function valve. The apparatus includes a primary fluid conduit, a secondary fluid conduit, and a valve. The primary fluid conduit flows from an exhaust manifold to an outlet through a high pressure turbocharger and a low pressure turbocharger. The secondary fluid conduit flows from the exhaust manifold to an outlet through the low pressure turbocharger. The valve has two flow passages—the first flow passage is a variable restriction within the primary fluid conduit, and the second flow passage is a variable restriction within the secondary fluid conduit. Turning the valve one direction from a nominal position controls the flow ratios in the primary and secondary fluid conduits, while turning the valve in the other direction from the nominal position controls exhaust braking.
