Description: |
Abstract:
My invention relates to that class of valves in which a variable cutoff is effected by means of a slide valve or valves working within the body of the main valve; and it consists in making the internal cutoff valve or valves to fit closely, life pistons, in the passage in which they slide, ands in extending the steam-ports nearly or quite around such passage, so that they can be made very narrow, and the valves caused to cut off the steam almost instantaneously.
Claim:
The main slide-valve, having ports S S' and a substantially-cylindrical passage, C, in combination with piston cut-oft' valves D D, closely fitting the cylindrical passage. |
