ABSTRACT:
A mixing head for a high velocity reaction injection apparatus for mixing and dispensing two or more liquid components. The mixing head includes a mixing chamber with two or more inlets for the separate components and an outlet for dispensing the mixed components, and an injection housing for injecting each component through a corresponding inlet. Component flow is directed through a flow accelerating passage in the injection housing prior to injection into the mixing chamber, for imparting a pressure drop in the component on the downstream side of the passage, and means are provided for selectively blocking the inlets for terminating the dispensing of the mixed components and thereby increasing the component pressure in the injection housing downstream of the passage. A recirculation line communicates with each injection housing downstream of the passage, and means responsive to component pressure downstream of the passage directs the flow through the recirculation line when the mixing chamber inlet is blocked, and blocks the flow into the recirculation line when the inlet is open.
