I'm having trouble understanding expansion valves.
Gas leaving a diffuser increases its pressure as the cross-section increases (i.e as the gas expands), like in a compressor. We convert kinetic energy in potential energy. That I understand.
But in a expansion valve, pressure drops as the gas expands.
There seems to be a contradiction, please explain to me where I am wrong!
Thanks
