ABSTRACT:
An exhaust gas recirculation valve assembly is provided for controlling the recirculation of exhaust gases in an internal combustion engine. The assembly includes a fixed body portion having an exhaust inlet and an exhaust outlet port and an adjustable exhaust back-pressure transducer portion movable within the valve. A diaphragm is attached to the body and to the upper and lower housing shells of the transducer to define in the body portion a vacuum chamber on one side and an atmospheric chamber on the other side. A second atmospheric or air bleed chamber and an exhaust chamber are provided by portions of the diaphragm in the transducer portion. The transducer has an air bleed valve responsive to exhaust back pressure which controls the vacuum in the vacuum chamber for effecting movement of a valve for controlling flow between the inlet and outlet. The back pressure transducer has an adjustment which includes a threaded member extending through the upper housing shell and engaging an annular seat registered over the upper end of a biasing compression spring, the lower end of which reacts against the transducer diaphragm. Selective advancement or retraction of the threaded member is effective for varying the magnitude of the biasing force on the diaphragm portion within the transducer.
