    摘要: A system and the equipment for economically enhancing recovery of hydrocarbon fluids from a subterranean reservoir in which a plurality of production and injection wells are formed. High grade steam from a common source is mixed with relatively cold water at each injection well to be treated. To avoid, or substantially reduce condensation shock in the water/steam mixer, the high velocity cold water is initially heated in a steam compartment with minimal contact between the two fluids. Thereafter, the steam and the water are introduced to a heat exchange chamber in which the temperature of the water is raised prior to the two streams being merged for injection into a well as either heated water or as low quality steam.

    摘要: A fuel priming system for spark ignited internal combustion engines includes a manually actuated plunger pump for delivering liquid fuel from a tank to a reservoir chamber formed in part by a flexible diaphragm. A fuel injection passage leads from the reservoir chamber through a flow restricting orifice to an injection point formed in the engine intake air flow passage downstream of the carburetor venturi. The injection system provides for enriching the fuel-air mixture during cold starting while minimizing the chance of engine flooding. The finite fuel volume in the reservoir chamber also provides a sufficient quantity of fuel for automatic control of a rich fuel-air mixture during engine warm-up.
