From this point the exhaust remains open until the crank reaches the position OE
, when it closes and compression takes place until it agairı reaches OS for
admission and one revolution is completed . By placing the Zeuner diagram upon

It will be noted that the action is practically identical in both cases , the steam
admission taking place at the point 7 , and the exhaust closure occurring and
compression beginning at the point 8 , with the main - pin at the same point in its

It has been repeatedly shown that if the pre - admission of steam amounts to a
sufficient quantity to cause compression , a marked increase in steam
consumption is shown . The real need is the readiness of admission of steam at
the time ...

... finish of the piston's stroke and the resultant compression will produce the
cushioning effect just as well — and more economically , —as evidenced by the
quoted authority , than by means of any pre - normal opening of the admission
port .

A. — The advance of the valve causes an earlier closing of the exhaust of the
used steam from the cylinder , thereby creating higher compression ahead of the
piston - between the piston and the cylinder head toward which it is travelling ;
