ABSTRACT:
A steam supply control device is disclosed which is adapted for use with an electro-hydraulic governor so as to control the rotational speed of an auxiliary turbine such as a cargo oil or ballast pump turbine, a generator turbine or the like. The device can prevent the excessive momentary increase in rotational speed even in case of a sudden decrease in load such as air draw in pump, and can also control an extremely low rotational speed.
