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 Meyer's expansion valve Flywheel Governor D-slide valve Meyer's expansion valve Flywheel Governor D-slide valve ANSWER DOWNLOAD EXAMIANS APP
