.1. Field of the Invention This invention relates generally to a system for achieving a desired flow rate of vapor and liquid (e.g., fuel) through a fuel line, and, more specifically, to a system which provides desired vapor and liquid flow rates from a fuel supply to a vaporizer, with a desired reduction in vapor and liquid flow at low engine speeds. 2. Description of the Prior Art Many diesel fuel injection systems use a fuel supply to an engine fuel injector which is coupled by a fuel line to a vaporizer in which the fuel is vaporized. This fuel is supplied to a combustion chamber in the form of a vapor mixture which is easier to atomize and burn. These systems also typically include a vapor throttle valve to control the flow of vapor through the fuel line to the engine. The vapor throttle valve is often located in the fuel line at the connection between the vaporizer and the fuel supply, to control the flow of vapor. If the vapor throttle valve is allowed to act independently of the flow rate of fuel to the engine, vapor flow to the engine will be inversely proportional to engine speed, and the engine will operate most efficiently at high engine speeds. This is due to the increased temperature of the vapor throttle valve at low engine speeds, and the increased amount of vapor throttling at higher engine speeds. In such a system, the vapor throttle valve must be carefully calibrated in order to operate effectively at all engine speeds. On the other hand, if the vapor throttle valve is fully actuated at all engine speeds, fuel flow to the engine will be relatively constant at low speeds, and will vary more at high speeds. This results in less efficient operation of the engine at low engine speeds, and in low engine speed blow-by of vapor into the combustion chamber.After the summer heat of the day, the Friday evening chill was inviting. Behind the ornate columns of the Museum of Contemporary Art, gallery-goers walked around the courtyard, past the faded spires and red brick of the State Capitol building, and into a subterranean room. In an old seam of that building, the Denver Women’s Art Center, I was swept into the embrace of a small but eclectic assemblage of artists. Kirstin Ross’s “Dreamcatcher,” above, is an exquisite assemblage of more than 200 old seed catalogs, part of a series that, according to the artist, references the way “dreams are nest
