[quote user="Hugh Jampton"][quote user="gabe"] <P>I know this is a silly question for someone who knows anything about these things, but how does a steam engine go in reverse? Do the pistons merely move in the opposite direction?</P> <P>Gabe</P> <P>[/quote]<BR><BR>If you go to this site<BR><A href="http://www.tcsn.net/charlied/">http://www.tcsn.net/charlied/</A><BR>and download the <U><FONT color=#ffffff><A href="http://www.tcsn.net/charlied/valgr10a.zip">Windows Valve Gear Programs File 10A, 1.27 MB, Version 2.7</A><BR></FONT></U><FONT color=#ffffff><FONT color=#000000>and unzip it, there's some executables you can play with that shows what happens when you shift into reverse and vary the cutoff.<BR><BR></FONT></FONT>[/quote]</P> <P>In so doing you will note, though, that the relationship between the movement of the pistons and the valves is the same either in forward or reverse. If it's an outside admission valve, it will move ahead of the piston by approximately 90 degrees, if inside admission it will follow the piston by approximately 90 degrees. The approximately comes in because of the lead, which in "outside" valve gears is provided by the combination lever.</P> <P>Ol' Ed</P> <P> </P> <P> </P>
