Description: |
| Abstract:
The object of my invention is to provide a valve of the class known as slide valves, with means whereby the valve will be yieldingly held by steam pressure from the steam chest against the valve seat at such times during the stroke of the valve as there is an outward pressure upon the inner surface of the valve caused by the induction port pressure of the engine.
Claim:
The combination of a steam chest, a valve seat having induction ports, a slide valve on the valve seat, a steam chamber formed on the outer surface of the slide valve and closed from communication with induction ports at all positions of the slide valve, a valve cover within the steam chest being provided with a 'passageway designed to admit steam from the steam chest into said steam chamber during a portion of the valve stroke. |
