4984. Matricardi, G. Feb. 28. Generating combustion products under pressure. - A cylinder a having a combustion chamber at each end contains a piston c propelled by explosions which take place alternately at each end. During i t s movement, the piston compresses combustion products and air on one side, and draws in air and a combustible on the other side. The cylinder a is in communication with the storage reservoir through valves d, d', chamber e, and pipes f. Combustible is supplied through pipes j, j<1>, chambers m, m<1>, holes l, l<1>, and valves k, k<1>. On the movement of the piston to the right, burnt gases and air are expelled through the valve d<1>, and burnt gases escape past the valve d when it has been uncovered by the piston. This escape takes place until the pressure in the cylinder is equal to that in the reservoir when the valve d closes. Further movement of the piston draws in air which has been caused by casings h to traverse the toothed cylinder ribs i through the valve b and compresses the air and gases in the right end of the cylinder prior to an explosion therein. A similar cycle takes place on the return stroke of the piston. At starting,- compressed-air or an explosion charge may be admitted by cocks o, o<1>.
