Tangential-Entry Injector With Internal Reed ValveLiquid-spray-injecting device provides designed pressure drop versus rate of flow to help meter flow. Includes cylinder with tangential entry slots and internal reed valve. Tangential entry imparts swirling motion to liquid, resulting in finely atomized liquid spray. Reeds vary flow areas of entry slots by deflecting in response to pressure of liquid. Variation alters pressure-versus-flow characteristic. Device used to provide wide range of throttleability for liquid fuel injected into combustion chamber or engine.
