Title: Carburetor

Abstract

A device is described for feeding a fuel/air mixture for fueling in internal combustion engine, comprising: (A) fluid jet carburetor means having a combustion air path, a mixing zone in said combustion air path for fuel/air contact, a fuel inlet to said mixing zone and a fuel outlet for recycled fuel from said mixing zone whereby, in use, a flow of fuel passes from said fuel inlet to said fuel outlet across the flow of combustion air at said mixing zone in direct contact with the combustion air; (B) fuel/air mixture flow rate control means interposed between the said mixing zone and the outlet end of the device; (C) sensor means responsive to at least one parameter of at least one of said device and said internal combustion engine; (D) means in said combustion air path, upstream of said mixing zone, for concentrating the flow of combustion air to a greater or lesser extent onto said mixing zone for maintaining the richness of the fuel/air mixture leaving said fluid jet carbuertor means at a desired value in response to signals from said sensor, the means for concentrating the combustion air at the zone of direct contact being a movable concentratingmore » vane means, a suction tapping in the combustion air path between said zone of direct contact and the control vane means, and said sensor means comprising an aneroid capsule comprising first and second chambers and a flexible diaphragm which separates said first and second chambers, said first chamber being connected to said suction tapping, said first chamber of the aneroid capsule being also connected to atmosphere, wherein a solenoid valve operated in response to engine operating parameters is included between said first chamber and the atmosphere.« less
