ABSTRACT:
A thermal liquid pump suitable for use as a fuel injector is described; when used as a fuel injector hypergolic combustion is possible. The pump includes a space or chamber that is connected to a fuel supply source. A check valve admits the fuel from the fuel supply into the chamber wherein an electrical heating coil heats the fluid within the chamber. The fuel confined in the chamber is not permitted to vaporize and the increasing temperature creates increasing pressure through thermal expansion of the fuel. A delivery valve is provided in the chamber that is electrically actuated to open and discharge the pressurized fuel into a combustion space. When an appropriate amount of fuel has been discharged, the delivery valve is closed and additional fuel is admitted to the chamber through the check valve.
