some basic ideas/drawings for steam engine valves
solenoid sucks the bolt in, so i gota change how the spring is set up in my diagram.
will the metal plate on top have an adverse effect on the magnetic field?
Item# SP-50095 NY-WSYM
needs a governor
 2 valves per cylinder, cam for each
mark pointed out the difficulty of cam design and efficiency,
temperature flow control
temperature sensor in the boiler or somewhere
could control flow of water, if its too hot pump more water to cool boiler reservoir, too cold turn off.
could be used to govern pump speed? by controlling temperature?
one double action valve switches between two cylinder inlets. need another for outlet.
4 single action would give better control, independent cam for each valve
could you mount so that cam shaft operates lever? and run hose to pistons? seems like there would be loss.
