- Abstract
"This invention relates to valves for controlling the operative parts of self-propelled torpedo-boats and methods of actuating same. It has for its object the construction of such valves and manner of operating them, whereby the liability of their freezing, due to the rapid expansion of the gas, either in liquid or gaseous form (and which is employed as the motive force) will be entirely obviated.
