Abstract

A clearance volume valve for controlling cylinder compression at varying engine speeds in a steam engine. At the injector of each cylinder, a clearance volume valve is hydraulically operated in response to changes in engine RPMs to thereby control opening and closing of an inlet to a sealed tube that extends from each cylinder of the engine. At lower engine RPMs, the clearance volume valve opens the tube inlet to increase the volume of the cylinder, thereby lowering compression and relieving back pressure against an incoming change of super-heated steam. At higher engine RPMs, the clearance volume valve is hydraulically operated to close the tube inlet, thereby reducing the total clearance volume and raising the cylinder compression for greater efficiency at higher engine speeds.
