Title: A view of some different heads Post by: Hydros on June 30, 2007, 01:24:07 AM From left to right
Unknown, copper in color. Notice the dish shaped head.

Not a bad idea...

Some brake master cylinders are made to move fast and then take up the load. They have a small pistion area and as the piston travels it opens into a larger diameter. This is an area that might be very useful, good going 87G Title: Re: A view of some different heads Post by: 87gbody on December 14, 2012, 07:41:12 PM Man that's a good one, I need to think this one out, what a great observation. you may be on to something here... Some brake master cylinders are made to move fast and then take up the load. They have a small pistion area and as the piston travels it opens into a larger diameter. This is an area that might be very useful, good going 87G So it starts off making pressure, then moves to volume? I guess you could call that a "progressive cylinder" or something. I'm going to google that master cylinder setup, post up a pic or info if you have it handy. I don't think it would take much to have a dome machined into an existing cylinder.

I asked a few friends about this, they all agreed that the force only acts on what is perpendicular to it, meaning no difference. However I did find an old "google answer" which I found interesting: "The pressure acts on what you might call the projected area of the piston. The projected area being the area that would project onto a plane perpendicular to the axis of the piston." I'll be sure to post any more info I find.

I can see all sorts of things happening with this if is it proved to be a benefit, from cylinders to piston pumps to hybrid suspensions. |
