Abstract:
An exhaust gas heat recovery system includes a housing assembly, a valve assembly and a heat exchanger. The valve assembly is disposed within the housing assembly and includes a shaft and a plate. The plate is rotatable between a first position whereat exhaust gas flow through a first fluid passageway is allowed and exhaust gas flow through a second exhaust gas passageway is prevented, and a second position whereat exhaust gas flow through the second fluid passageway is allowed and exhaust gas flow through the first gas passageway is prevented. The heat exchanger assembly includes a heater core having a working fluid circulating therein. The working fluid is in thermal communication with fluid in the heater core. The housing assembly includes first and second shells attached to each other at a joint. An axis of the shaft being at the joint of the first and second shells.
