2106674 9218251 PCTABS00016 An improved multi-component mixing and dispensing apparatus having a replaceable nozzle (16) associated therewith in which plural components are mixed before dispensing thereof. The apparatus includes improved component feed systems to maintain each component to be mixed and dispensed in a segregated condition until mixing is desired. The component feed systems include internal passages (40, 42) within the apparatus and selectively actuated valves (84) which are operable to allow flow of a component to an outlet port (44) formed in the apparatus. A mixing and dispensing nozzle (16) may be coupled into the apparatus so as to communicate with the outlet ports (44) of the component feed systems. The component feed systems include self-cleaning structures to ensure that the internal passages remain unblocked, and the apparatus further includes structure (97) to selectively render the apparatus non-operational when desired. A replaceable mixing and dispensing assembly (100) is disclosed, which allows more thorough metering and mixing of plural components within a kinetic mixing chamber (112), and may include a second stage (120) of mixing if desired.
