The pump Injector is a brass valve with a needle type regulator that is adapted onto the intake side of a pump. This injector enables a person to regulate the flow of a liquid composition into the main flow of water or other liquid that is being pumped by adjustment of the needle valve.Needle & Gauge Valves Specifically, the liquid that is to be used is in a container. A clear plastic hose runs from the container and connects to the pump injector. The vacuum from the pump sucks the liquid from the container up through the plastic hose through the hose connection sleeve and down past the needle valve head and along the flattened side of the brass valve.Globe Valves It is then sucked through the 1/16 inch side port hole and is regulated by the needle valve. The regulated flow passes on down into the liquid being pumped. A pump injector valve apparatus comprising: an externally threaded needle valve member having an adjusting head on one end thereof and a tapered shank at the other end thereof; a valve seat member with a longitudinal passage therethrough having a side port opening through the side wall of the passage intermediate its opposite ends,MULTI-FUNCTIONAL WATER PUMP CONTROL VALVE said passage being threaded at one end for receipt of said needle valve member so that the tapered end thereof is positioned adjacent said side port; connection means including a sleeve surrounding said needle valve member and said valve seat member, for connecting said valve apparatus to an auxiliary liquid supply and for transmitting said auxiliary liquid through said side port into said passage, said adjusting head of said needle valve member being contained within the sleeve; means provided on said adjusting head for rotating said needle valve member to adjust the flow of said auxiliary liquid through said side port; pump connector means including an externally threaded tubular connector member, for connecting the outlet end of said passage in said valve seat member to a liquid pump for injecting said auxiliary liquid into the main pumped liquid; and compression means including a compression nut, for clamping said valve seat member between said sleeve and said pump connector member, said sleeve having an external flange at one end thereof which is engaged by said compression nut and said nut being threaded onto said connector member to clamp said sleeve between said nut and said connector member.
