Abstract
A trigger operated fluid delivery system for dispensing two different fluids is disclosed. The fluid delivery system includes a first container having a first primary fluid, a fluid inlet conduit in fluid communication with the first container, and a pump for drawing the first fluid through the fluid inlet conduit and into a pump chamber. A fluid discharge conduit is located downstream of the pump chamber. The fluid discharge conduit is in fluid communication with the pump chamber and a discharge orifice. The pump discharges the first fluid from the pump chamber into the fluid discharge conduit. The fluid delivery system also includes a second container having a second fluid, that delivers the second fluid into the fluid discharge conduit. The second fluid mixes with the first fluid when the first fluid is discharged into the fluid discharge conduit such that a mixture of the first fluid and the second fluid is discharged through the discharge orifice.
