Abstract: The pressurized chemical dispenser of the present invention is coupled to a conduit through which a supply of pressurized fluid is circulating. The system to which the invention is coupled must also include a device coupled in series with the conduit which creates a pressure differential across the input and output sides of the device such that the pressure on the input side exceeds the pressure on the output side. The chemical dispenser includes an offset cavity which is coupled to the conduit on the higher pressure side of the pressure differential device. A fluid tight reservoir stores a supply of fluid soluble chemical and includes an input and an output conduit. The input conduit has a first end which is coupled to the reservoir and a second end which is coupled to the offset cavity. The first end of the output conduit is coupled to the reservoir while a second end is coupled to the fluid conduit on the lower pressure side of the pressure differential device.
