Talk:Piston valve

From Wikipedia, the free encyclopedia

Piston valves are also used in most steam locomotives.

Not quite sure how to handle this. The valves used in a steam locomotive are very similar in principle to those used in brass instruments, so there's something to be said for dealing with both in a single article. Andrewa 00:39, 6 October 2005 (UTC)

[edit] Merge proposal (2 January 2006 NetherlandishYankee)

oppose: I agree with Andrewa. The piston valve in a brass instrument is but an example of a piston valve. Although the author of this article clearly had this specific application in mind, I propose that a more reasonable resolution is that the article be broadened to discuss piston valves in general. Notice that this article is appropriately marked as a stub. The external links have good information about the nature and function of a piston valve. Someone should endeavor to bring that information into this article.--Jcoman 21:22, 5 January 2006 (UTC)

neutral: If it was deemed a merge then it'd be for a section move only. As correctly noted above, a piston valve is not exclusive to brass instruments, but I don't see a problem with merging the appropriate section into brass instruments and leaving this page for someone to add the necessary steam (and other) related use to. I'd point out that rotary valve also has material that would need to be merged, for the sake of consistency if nothing else. — Graibeard 05:10, 26 January 2006 (UTC)

oppose. Merge some of the content if that is seen to be helpful, but leave the more general article applying to all piston valves. There were once linear-acting valves used at the chimney bases of some open hearth furnaces, but I don't know whether they were called piston valves. I think they were called after their inventor, as were the rotary valves which replaced them. Watch this space! Andrewa 01:04, 27 January 2006 (UTC)

I have removed the merge notice. There seems no support for the proposal, and its basis has been removed by the latest edits. Andrewa 17:21, 4 February 2006 (UTC)

[edit] Update to the brass instrument data

As well as providing some information on steam engines, I've also made some additions and corrections to the information on brass instruments. Andrewa 01:04, 27 January 2006 (UTC)

yeah, shouldn't there be a bit about Brass valves needing some sort of lubrication, like valve oil?

[edit] Steam engines

This section was seriously inaccurate, so I have re-written it. I have left the bit about James Watt but I think that is inaccurate too. I think James Watt used plug-cock valves in his engines but I don't know a lot about such early engines so I will leave that to someone else. 82.21.65.109 16:33, 16 March 2007 (UTC)

[edit] Spud guns

Perhaps I'm prejudiced, but do we really want spud guns as the first item? I'd put it last. 82.21.65.109 16:55, 16 March 2007 (UTC)

No objections received, so I have made the change. Biscuittin 14:40, 11 September 2007 (UTC)

[edit] Machine configurations template

I don't think this template is appropriate for this article. Most of the machines listed don't use piston valves. Biscuittin 14:44, 11 September 2007 (UTC)

[edit] Two articles

We have two articles, piston valve and piston valves. Should they be merged? Biscuittin (talk) 12:10, 30 March 2008 (UTC)
