ABSTRACT OF THE DISCLOSURE PLURAL COMPONENT DISPENSING APPARATUS 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 rota- table valve member in a combination retainer and seat. The valves are connected to first and second pinion gears, re- spectively, and a rack engages each of the pinion gears. The rack is attached to a piston which is disposed for reci- procation 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 mix- ing 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 oppo- site the first and second orifices for dispensing the mixed components from the apparatus. When fluid pressure is pro- vided 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.
