Abstract

Methods and apparatus for dispensing a fluid with dispersed particles therein are disclosed which include a reservoir containing the fluid and dispersed particles. The fluid is agitated to maintain dispersion of the particles. The output of the reservoir is provided through a filter to a three-way valve and pressurized as required. The common port of the three-way valve is connected to a print module controlled by a programmable controller. Bypass flow is provided to increase the flow rate through the system. The system may be operated in either the demand mode or the continuous mode.
