ABSTRACT:
The present invention discloses an improved apparatus for injecting additives into a stream of fluid passing through the apparatus. The apparatus has a housing adapted for connecting to a source of fluid and to an external source of additive and also has an outlet through which the intermixed fluid and additive pass. Fluid entering the housing drives a turbine means, which converts the movement of the fluid into a rotary force. The turbine means is connected to a transmission means which changes the high-speed, low-torque rotary force produced by the turbine means to a rotary force having slower speed but higher torque. The transmission means drives a positive displacement pump means which draws additives from the external source into the fluid passing through the apparatus at a rate which is determined by the speed at which the turbine means rotates. The positive displacement pump means utilizes a wobble disk to convert the rotary motion produced by the transmission means to the reciprocating motion necessary to drive the pistons in the pump means. Additionally, the pump means incorporates multiple cylinders to allow either mixing of additives from various sources with the fluid passing through the apparatus, or to provide a method of controlling the concentration of a single additive injected into the fluid when all of the cylinders are connected to the same additive source.
