Patent ID: 8887743

Claim:
A chemical delivery system for distributing chemicals within a car wash, comprising: a motive fluid source including a pressurized motive fluid; a distribution manifold having a plurality of distribution ports, and at least one chemical delivery manifold including a plurality of venturi injectors, each venturi injector have a motive fluid inlet, a chemical inlet and a mixed solution outlet, each venturi injector adapted for operation at the direction of an individual control signal selectively controlling flow of the pressurized motive fluid through each venturi injector, and wherein each venturi injector is adapted for independently introducing a different concentrated chemical solution, wherein the pressurized motive fluid is supplied to the distribution manifold and to each chemical delivery manifold through a corresponding distribution port, the pressurized motive fluid being provided through a distribution line to each motive fluid inlet at a constant pressure such that the corresponding concentrated chemical solution is mixed into the pressurized motive fluid within each venturi injector; and wherein the distribution manifold and the at least one chemical delivery manifold are mounted on a common frame.
