these thing are all interesting i have always wondered if an engine can be built from an Oldam coupling. i will think some on this for the next two weeks holiday, in Devon, without my computer. yours tomsid ps some old ideas about transmitting rotation https://www.econologie.com/fichiers/partager2/1...

pascal it is wonderful to see again the photos of your engine . i notice you may be using an Oldham coupling to transmit the rotation in the engine. this is interesting because one other engine uses an oldham coupling to transmit rotation, the Akasaka rotary. there is practicaly no information on th...

Pascal i think this is the field engine. thanks for the other bevel gear engine patents. they even anticipate my idea for more than two gears. https://www.econologie.com/fichiers/partager2/13088378905FdKdn.GIF the animation MATHCURVE is similar to the davis engine . it uses a cone rather than a disc...

https://www.econologie.com/fichiers/partager2/1308481589UHbnPG.GIF this patent is similar to something i have been working on https://www.econologie.com/fichiers/partager2/1308481675Yl1Obd.jpg this is an example of a pump that uses centrifugal and positive displacment at the same time. yours tomsid

many of the designs for rotary internal combustion come from rotary steam engines. the Filtz was a successful rotary steam engine. http://www.aqpl43.dsl.pipex.com/MUSEUM/POWER/rotaryengines/rotaryeng6.htm#f there is also a conjecture that i am working on. "any rotary engine can be changed into ...

I know this as the filtz engine.

there seem to be many versions

this is the direction that i think would prove interesting as it has the posibility to use centrifugal displacmentas well as positive displacemet

have a good day

i feel from Beyer onwards progress is in a complicated direction. -------------------------------------------------------------------------------- We all want progress, but if you're on the wrong road, progress means doing an about-turn and walking back to the right road; in that case, the man who t...
