ABSTRACT:
A plural component dispensing system includes supplies which furnish first and second components under pressure to a dispensing apparatus having first and second valves, respectively. Each of the valves includes a rotatable valve member in a combination retainer and seat. The valves are connected to first and second pinion gears, respectively, and a rack engages each of the pinion gears. The rack is attached to a piston which is disposed for reciprocation in a cylinder in response to fluid pressure on one side or the other of the piston. Actuation of the piston in a first direction provides paths for component flow through the first and second rotatable valve members and through first and second orifices, respectively, into a mixing chamber. The first and second orifices are disposed to provide impinging streams of the first and second components, the impingement insuring complete and thorough mixing of the components. A nozzle is provided in the mixing chamber opposite the first and second orifices for dispensing the mixed components from the apparatus. When fluid pressure is provided on the other side of the piston, the first and second rotatable valve members are rotated to positions to block the flow of components into the mixing chamber.
