Abstract
A dual fuel heating source can have a dual entry valve unit with a main body at least partially defining a certain flow paths or channels therethrough. The dual entry valve can have first and second inlets and first and second outlets. The dual fuel heating source may also include a pressure regulator, an exit valve, a control valve and/or a manifold connected to the dual entry valve unit.
Claims23
A dual fuel heating source comprising:
- a dual pressure regulating unit for regulating the pressure of either of two different fuels at different pressures, comprising:
- a first main body at least partially defining a first flow path and a second flow path;

- and
- a second regulating unit outlet port;
- wherein the first flow path ends in the first regulating unit outlet port and the second flow path ends in the second regulating unit outlet port;
- a dual entry valve unit comprising:
- a second main body at least partially defining a third flow path and a fourth flow path;
- a first valve unit inlet;
- a second valve unit inlet;
- a first valve unit outlet port;
- and
- a second valve unit outlet port;
- and
- an exit valve comprising:
- a third main body at least partially defining a fifth flow path, a sixth flow path, a seventh flow path and an eighth flow path;
- a first exit valve inlet;
- a second exit valve inlet;
- a first exit valve outlet port;
- a second exit valve outlet port;
