Abstract
A device for mixing and ejecting a multi-component reactive mixture, which will not clog after a single and subsequent uses, is disclosed. The device has a cylindrical mixing space defined by upper, lower, and side walls. There are two entry ports into the mixing space defined by and tangent to the side wall. Two fluid component sources are fluidly connected to the entry ports and are pressurized such that two fluids, which react with each other, separately enter the mixing space. The side wall of the mixing space imparts a rotational motion to the fluids, which causes the fluids to thoroughly mix together before being ejected out through the exit orifice in either a spray or stream form. A valve stem may be provided, which is configured and dimensioned to substantially occupy the mixing space and to seal the two entry ports when it is in the closed position.
