Abstract
A non-clogging check valve assembly useful in the simultaneous dispensing of individual components of a two-part grouting material. Two opposed flexible outlet nozzles mounted adjacent one another in a body member allow the components to be dispensed in a mixing relationship. The outlet nozzles are dome-shaped and contain slot-like apertures to allow the dispensing of the components under pressure and to prevent the clogging re-entry of the components into the valve which would otherwise result from back pressures developed as the components combine and react.
