Exhaust heat recovery apparatus
Abstract:
An exhaust heat recovery apparatus includes a joining section extending from a downstream end portion of a second flow passage section to a first flow passage section. The joining section has a communication port formed proximate a valve shaft for directing an exhaust gas from the second flow passage section into a housing section. A valve includes a first valve body supported by the valve shaft for closing a downstream end portion of the first flow passage section, and a second valve body extending from the first valve body for closing the communication port. The first valve body and the second valve body are disposed circumferentially of the valve shaft. The second valve body has an arc-shape having a center provided by the valve shaft.
