| No. Patentee. Title. 525,816 G.R.Tunisic. Fuel vapourizers for internal combustion engines. In a vapourizer of the type in which fuel is injected into a heated chamber past a needle control valve (the vapour produced being afterwards delivered into the air flowing through the engine intake manifold) the needle valve is initially opened by hand but thereafter is controlled by the vacuum in the intake manifold. 525,823 Works Development Co.Ltd. Admission ports to the cylinders of two stroke internal combustion engines. and J.E.Irlich Invention concerns two stroke engines in which multiple working pistons have a common combustion space and is concerned with so shaping the operating edge of the sliding member which controls the admission ports, or the walls of the ports themselves that abrupt changes in speed of mixture entering combustion chamber are avoided. 525,844 W.G.Hay. Seals for rotary or oscillatory valves for internal combustion engines. A rotary valve has a sealing member which is laterally slideable with reference to the valve and rings analagous to piston rings embracing cylindrical surfaces act to protect the sealing member from being urged toward the valve by the pressure of the combustion gases. 525,862 R.P.Pescara Combustion chambers for internal combustion engines. Internal combustion engine has combustion chamber triangular in plan a valve is in each angle of the triangle, two are exhaust - a larger, the inlet has an inclined stem, the ignition plug is placed approximately horizontally opposite the space between the two exhaust valves. | ||
