An inside admission valve does its work in exactly the reverse manner to that of
the one just described , and all inside admission valves in common use are of the
piston type , which in construction are really two ordinary pistons with metal ...

2 the valve is of outside admission ; the eccentric E is just 90 degrees from the
main - pin , and the valve is in an exactly central position on its seat — therefore
without lead . If the steam throttle should now be opened , this engine could not ...

push the valve forward — the direction in which the piston will have to travel : and
to accomplish this , the position of the eccentric must be changed to a point on
the wheel exactly its opposite in location - 90 degrees on the other side of the ...
