Abstract
Back pressure regulation in a system including an evaporator is achieved by a valve having an inlet adapted to be connected to an evaporator, an outlet and an interposed poppet and valve seat. A fluid motor is operative to move the poppet and the fluid motor is controlled by a control fluid inlet, a control fluid outlet and a pressure response valve in fluid communication with the inlet.
