label: Description
content: The model represents a stationary cylinder filled with oil within which turns a paddle wheel driven by the engine at a speed dependent upon the velocity of the engine. Also within the stationary cylinder and surrounding the paddle wheel is a hollow cylinder, which is hung loosely upon the shaft of the paddle wheel and is free to revolve independently of it. This cylinder has a series of blades or abutments projecting from the inner side of its rim, so that as the paddle wheel causes the oil to revolve in the cylinder the moving oil will come into contact with the abutments and tend to turn the loose cylinder. Attached to the loose cylinder is a pinion that meshes with a toothed sector, which, in turn, is connected with the counterweight and so tends to oppose the turning of that cylinder. As the height to which the counterweight will be raised is a function of the velocity of the engine, this velocity can be governed by properly connecting the counterweight to the cut-off or throttle valve.
