Abstract: 547,083. Two-stroke engines; valves. BROWETT LINDLEY (1931), Ltd., J., and HUTTON, J. April 11, 1941, No. 4861. [Classes 7 (ii) and 7 (vi)] In a two-stroke engine with magneto or coil ignition, a vacuum pump extracts the exhaust gases from the power cylinder through a cooler or exhaust box in order to reduce their volume, temperature and pressure, so that the combustible mixture is drawn into the cylinder in the wake of the exhaust gases, and the charge is attenuated or throttled for the lower loads to maintain uniformity of the mixture in the cylinder. As shown, an enlargement 5 of the engine piston 1 draws the exhaust gases from a piston-controlled exhaust port 4 through a cooler 10 when an inclined inlet port 3 is opened, to admit mixture from a carburetter 11. A governor-controlled throttle 12 on the carburetter reduces the throttle opening on low load, and a valve 22 enables the mixture from the carburetter to be conveyed through a pipe 23 and valve 24 to the crank case and compressed therein before delivery through oneway valves 25 to the inlet port 3. The valve 24 may be a plunger on the stem 26 of a camactuated valve 17 to which the exhaust is discharged from the suction space 8. The engine may be air-cooled'by a flywheel fan 29 delivering air through a duct 30. In a modification, the exhaust gases are drawn through the cooler 10 by a rotary-vane blower.
