Abstract
A pressure transducer (10) for use in internal combustion engine exhaust gas recirculation systems is disclosed having low inertia moving components for improved response time and a low cost diaphragm mounting arrangement. Upper (12) and lower (14) housing shells define in cooperation with a diaphragm (21) and an upper (26) and lower (44) reaction plates fabricated from light weight plastic, a vacuum chamber (72), control chamber (96) and a vent chamber (102). The single diaphragm is connected to the inner wall of the housing by a clamping ring (48), thereby dividing the diaphragm into individually pressure responsive upper and lower portions.
