Abstract

1422010 Recirculating IC engine exhaust GENERAL MOTORS CORP 5 April 1973 [19 April 1972] 16284/73 Heading F1B [Also in Divisions F2 and G3] An exhaust gas recirculation control valve assembly of an I.C. engine comprises a valve seat 76 in a recirculation passage having an inlet 60 and outlet 64, a valve member 82 co-operable with the valve seat, a pressure responsive member 102 operable to position the valve members relative to its seat, and a passage 92 for subjecting the pressure responsive member to the pressure upstream of the valve seat in a chamber 104. The chamber is formed between an orifice plate 80 and the valve member. The pressure responsive member may be in the form of a bellows, Fig. 3, or a diaphragm Figs. 4, 5, 6 and 9 (not shown). The chamber 104 may be kept at superatmospheric or subatmos- pheric pressure. The valve member may be pilot operated Figs. 7, 8 (not shown) with the main valve controlled in response to induction pressure and engine temperature (Fig. 7).
