First Claim
1. A chemical delivery system, comprisinga body defining a main fluid flow passage through which a fluid passes;
- a storage tank for holding a chemical;
a first inlet nozzle by which a quantity of the fluid from the main fluid flow passage is delivered to the storage tank to be mixed with the chemical;
an outlet nozzle by which a quantity of the fluid mixed with the chemical is returned to the main fluid flow passage from the storage tank; and
an adjustment dial having a plurality of orifices of varying diameter that are capable of being individually placed into relation with the first inlet nozzle to control the amount of fluid that enters the first inlet nozzle from the main fluid flow passage.

Abstract
A chemical delivery system having a body defining a main fluid flow passage through which a fluid passes and a storage tank for holding a chemical. An inlet nozzle delivers a quantity of the fluid in the main fluid flow passage to the storage tank to be mixed with the chemical and an outlet nozzle return a quantity of the fluid mixed with the chemical from the storage tank to the main fluid flow passage. An adjustment dial having a plurality of orifices of varying diameter that are capable of being individually placed into relation with the inlet nozzle may be used to control the amount of fluid that enters the first inlet nozzle from the main fluid flow passage. Furthermore, an outlet nozzle trap in fluid communication with a vent port of the outlet nozzle may be placed in fluid communication with a fill control port of the inlet nozzle. The fill control port is used to direct fluid to the outlet nozzle trap to control venting of air from the storage tank to the main fluid flow passage via the vent port.
