ABSTRACT:
An exhaust gas pressure responsive valve assembly includes a first body of resinous material, a second body of metal material secured to the resinous material, a diaphragm member having an outer periphery held between both of the bodies so as to define an atmospheric chamber on the side of the resinous body and an exhaust gas pressure chamber on the side of the metal body, a spring biasing the diaphragm member against the exhaust gas pressure within the exhaust gas chamber, inlet and outlet ports provided in the resinous body, a passage provided in the resinous body for connecting the inlet and outlet ports, at least one metal plate secured to the diaphragm member, a guide member of resinous material secured to the metal plate, and a valve mechanism arranged within the guide member for controlling fluid communication between the passage and the atmospheric chamber in response to movement of the diaphragm.
