Abstract
An injector for a fluid delivery system is provided to deliver precise volumes of a plurality of fluids in sequence to a treatment reservoir. The injector is in fluid communication with a positive displacement pump which accepts fluid from a fluid source. The injector includes a spring loaded plunger, an end of which contacts a diaphragm adapted to seal an injector inlet from an injector outlet. The end of the plunger is shaped to seat the diaphragm against the injector outlet and to position the diaphragm away from the injector inlet.
