  • Patent number: 4099703
    Abstract: An adjustable needle valve provided with an orifice and a needle valve stem is characterized by a finely calibrated adjustment means connected to the valve stem for controlling variations in the flow of fluid in a system, the needle valve stem being biased so as to be normally urged toward an orifice to restrict the flow of fluid, but which can be manually retracted from the orifice to a position allowing a full stream of fluid to flow through the orifice to flush out foreign particles which may have lodged between the orifice and the needle valve stem. When the needle valve stem is released, it returns to its previously adjusted position within the orifice without having to be reset by the adjustment means.
