Patent ID: 7967501

Claim:
A pump for controllably dispensing an additive into a liquid stream and mixing therewith, the pump comprising: a) a pump body comprising a housing having a passage therethrough with a liquid inlet end into which a liquid stream is introduced, the liquid inlet end comprising an adapter which is adapted to fit an inside diameter of a liquid supply hose, and an outlet end from which a combination mixture of the additive and the liquid stream is discharged; b) a flow regulator positioned inside the passage and configured to adjust the rate at which the incoming liquid stream enters the passage; c) a turbine supported by a cylindrical turbine base for rotation within the passage of the pump body between the liquid inlet end and the outlet end, the passage being so shaped that the incoming liquid stream flowing in the passage strikes the turbine in a manner as to impart rotation thereon; d) a cylindrical threaded connector having a first end fixedly attached to an auger housing and a second end fixedly secured to the cylindrical base of the turbine, the auger housing comprising an auger housing entrance end into which an additive is introduced and an auger housing exit end from which the additive is discharged, the auger housing exit end in fluid communication with the passage of the pump body between the liquid inlet end and the outlet end, such that the additive discharged from the auger housing exit end mixes with the incoming liquid stream flowing in the passage of the pump body; and e) a helical lifting auger mounted on a supporting drive shaft fixedly attached to the turbine, the auger rotatably disposed within the auger housing so as to produce a fluid flow through the auger housing, the lifting auger configured to accept the additive from the auger housing entrance end; and move the additive through the auger housing to the auger housing exit end into the passage of the pump body, where the additive is mixed with the incoming liquid stream by the rotation of the turbine to produce the combined mixture of additive and liquid stream.
