In order to aid in the understanding of this invention, it can be stated in essentially summary form that it is directed to a chemical injector comprising a reservoir for containing a water solution of the chemical to be injected.Hydraulic control valves A parallel water flow stream has a Venturi therein so that water flow through the Venturi draws chemical solution from the atmospheric pressure reservoir, with flow rate being controlled by control of the chemical solution flow channel size. When the flow rate is insufficient to draw solution from the reservoir, a reciprocating pump can be actuated to inject the chemical solution into the main stream.

It is thus an object of this invention to provide a chemical injector wherein a reservoir is employed at atmospheric pressure, and the flow of solution from the reservoir to a main flow stream can be controlled.Water Power Control Valves It is another object to control the flow of chemical solution from the reservoir to the main stream by means of controlling the size of the solution channel. It is a further object to control the size of the solution channel by control of position of an external handle so that flow can be continuously regulated. It is another object to provide a manual reciprocating pump actuated by the same handle so that the structure can also furnish solution to the main flow stream by manual pumping, as well as control the inducted flow resulting from Venturi action.

The features of the present invention which are believed to be novel are set forth with particularly in the appended claims. WATER POWER CONTROL VALVEThe present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may be best understood by reference to the following description taken in conjunction with the accompanying drawings.
