Patent number: 6805149Abstract: 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 returns a quantity of the mixed fluid to the main fluid flow passage.Type: GrantFiled: May 30, 2003Date of Patent: October 19, 2004Assignee: E-Z Flo Injection Systems, Inc.Inventor: Dan Gilmore

Patent number: 6659117Abstract: A method of using a fluid injector in fluid communication with a fluid flow line where flow is transferred from the flow line into the fluid injector and back to the fluid flow line. An inlet flow is used to pressurize the storage tank and provide a solution to mix with injection solutions in the tank.Type: GrantFiled: February 14, 2003Date of Patent: December 9, 2003Assignee: E-Z Flo Injection Systems, Inc.Inventor: Dan C. Gilmore

Patent number: 6659128Abstract: A fluid injector made of pressure rated components that attach to a fluid flow line so that flow is transferred from the flow line, into the injection unit and back to the fluid flow line. The inlet flow is used to pressurize the storage tank and provide a solution to mix with injection solutions in the tank to provide an accurate preset or adjustable injection rate into the fluid flow line. Venproportioner ports provide an internal air release port and set injection ratios.Type: GrantFiled: February 14, 2003Date of Patent: December 9, 2003Assignee: E-Z Flo Injection Systems, Inc.Inventor: Dan C.

Publication number: 20030214132Abstract: A pipe connection fitting having at one end a tapered edge (1) which communicates at its base with tightening nut (2) which communicates with male pipe threads (3) which communicates with extension member (4) having an angle cut (6) with a flow port (5) through the center of the fitting. Positive differential pressure is created by installing a differential pressure fitting facing into the fluid stream of a flow line. Negative differential pressure is created by installing a differential pressure fitting facing away from the fluid stream of a flow line. Tubing connects the fittings to a pressure tank containing the fluid to be injected in the flow line. Fluid flow past the fittings in the flow line motivates flow from the flow line to the pressure tank and from the pressure tank back to the flow line. The fitting being made of rigid plastic or metal.Type: ApplicationFiled: May 22, 2003Publication date: November 20, 2003Applicant: E-Z Flo Injection Systems, Inc.Inventor: Dan Gilmore

Patent number: 6604546Abstract: 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.Type: GrantFiled: July 19, 2002Date of Patent: August 12, 2003Assignee: E-Z Flo Injection Systems, Inc.Inventor: Dan C.

Patent number: 6546949Abstract: A fluid injector made of pressure rated components that attach to a fluid flow line so that flow is transferred from the flow line, into the injection unit and back to the fluid flow line. The inlet flow is used to pressurize the storage tank and provide a solution to mix with injection solutions in the tank to provide an accurate preset or adjustable injection rate into the fluid flow line. Vent/proportioner ports provide back flow protection, prevent fluid from siphoning from the storage tank, provide an internal air release port and set injection ratios. A mixing control valve adjusts the injection ratios by mixing outgoing injection solutions with incoming fluid from the fluid flow line. Flexible bladders isolate one or more injection solutions within one storage container which are injected simultaneously at independent injection rates.Type: GrantFiled: June 17, 2002Date of Patent: April 15, 2003Assignee: E-Z Flo Injection Systems, Inc.Inventor: Dan C.
