ABSTRACT:
A thernopneumatic valve comprises a fluid channel plate defining a fluid port. A diaphragm plate is attached to the fluid channel plate. The diaphragm plate includes a displaceable diaphragm to selectively obstruct the fluid port of the fluid channel plate. A thermal isolating heater is connected to the diaphragm plate. The thermal isolating heater includes a thermal isolating heater body with a heating surface, a perimeter wall defining an extended axial cavity to confine a thermopneumatic working fluid that is used to control the position of the displaceable diaphragm, and a diaphragm obstruction structure to limit the motion of the displaceable diaphragm into the extended axial cavity.
