Inspiration for Steam Valve Design When I originally looked at the steam valve for the Burrell I read a number of references and article and then listed the following points: Smooth the steam flow path. Can the valve reliably shut steam flow off completely? Does the valve provide enough control? Does the valve work at … Read more
Looking for inspiration for a steam valve design. Thought I would share a bit of a search of the internet, books and reference papers. I’ve already discussed the different options for the Burrell Steam Valve principle of operation: Make a valve part of the saddle Fit a standard steam valve to the side of the … Read more
For the design of the Miniature Burrell Valve inspiration is coming from the Stuart 10V. Maybe more than inspiration, I’m measuring the valve dimensions and halving them. This Stuart engine I made over 40 years ago and it still runs like a dream. Hence I thought that these would be good dimensions to measure up … Read more
The transitional engine eccentric is the drive for the piston exhaust valve, an eccentric is a disc with the rotational centre offset to the centre of the disc. The transitional engine has been on the bench for quite some time and has gone through a number of design updates – basically there is no plan, … Read more
