Abstract

1349798 Spray carburettors SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 17 June 1971 [25 June 1970] 28544/71 Addition to 1224610 Heading F1B An I.C. engine carburation device comprises a passage 17, 28 which supplies a mixture to an induction pipe 1 via a slow running orifice 4, the rate of supply being controlled by a valve 39 responsive to engine speed and throttle opening and also operated on by hydraulic means 48-54 responsive to engine load to modify the slow running conditions of the engine. A push rod 48 responds to pressure in line 51 to open valve 39 to increase the flow of mixture to orifice 4 e.g. when an automatic gearbox associated with the engine is moved out of neutral. In Fig.2 (not shown), push rod 48 responds to the pressure in two cylinders (53a) and (53b) supplied by lines (51a) and (51b).
