Theory of Machine When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a Flywheel Meyer's expansion valve Governor D-slide valve Flywheel Meyer's expansion valve Governor D-slide valve ANSWER DOWNLOAD EXAMIANS APP
