When an explosion occurs theforce P is exerted in the direction of•( to A. This, of course, is due tothe fact that the pistons are connectedtn the point A through the medium ofthe connecting rod. There is also an-other force in the direction of C to. 8 SALMSON CANTON MANE RADIALTYPE ENGINE. B set up, due to the fact that the pistons trying to reach the point B, becauseit is guided in the cylinder, which is setradially to the centre B. Now, it iswell known to students of mechanicsthat wherever there is action, there isreaction equal and opposite, consequently there will be the reactions of the twoforces and , and the resultant,shown by the line XY, is resolved intothe force R on the leading edge of thecylinder, causing it torevolve. This principleanly applies to a rotaryengine and not to theradial engine, which isvery similar in out-ward the generalprinciples of engines,some of the more im-portant details will bedealt with. Of verygreat importance is themaintenance of com-pression. In an enginecompression is main-tained through the me-dium of well-fittingvalves, piston ringsand accurately madejoints, such as the joint between thecylinder and body, sparking plug andits mounting.
