Abstract

648,980. Exhaust systems. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Dec. 23, 1947, No. 33994. Convention date, Sept. 5, 1946. [Class 7(ii)] [Also in Group XXVIII] Exhaust gas from an I.C. engine cylinder is induced through an orifice C, Fig. 1, by primary air under pressure entering a chamber K through a series of peripheral tangential convergent nozzles T, Fig. 2, and the mixed mixture is delivered to an exhaust manifold where a pressure higher than inlet pressure prevails through an annular opening B coaxial with the inlet C and having its greatest radius smaller than the smallest radius of the inlet nozzles T and its smallest radius greater than the radius of the inlet C. The path of the primary fluid is first swirling-centripetal, then axial.
