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.
A plural component dispensing apparatus comprising first means for supplying a first component, second means for supplying a second component, a housing for providing a cylinder, a piston disposed for reciprocation in the cylinder in response to fluid pressure on one side or the other thereof, a trigger for controlling fluid pressure in the cylinder, the trigger being movably mounted in the housing, a rod connected to the piston and reciprocable therewith, rack means provided on the rod, first and second rotary valve means for controlling the flow of the first and second components from the first and second supply means, respectively, at least a first pinion gear connected to the first and second valve means and engaging the rack means, reciprocation of the piston causing rotation of the first and second valve means between first orientations providing flows of the first and second components and second orientations blocking flow of the first and second components, the first and second valve means and pinion gear being attached to the housing and the housing being sized to be hand-held and operated.
A plural component dispensing apparatus comprising means for providing first and second flows of first and second components, respectively, means for providing a flow of an operating fluid, a housing for defining a cylinder, the first and second flow-providing means and operating fluid flow-providing means being connected to the housing, a piston disposed for reciprocation in the cylinder in response to operating fluid pressure on one side or the other thereof, trigger means for controlling operating fluid pressure in the cylinder, the trigger means being movably connected to the housing, a rod connected to the piston and reciprocable therewith, rack means provided on the rod, first and second valves for controlling the first and second flows, respectively, the rod and first and second valves being movably mounted in the housing, the housing defining a first passageway providing communication between the first flow-providing means and the first valve, a second passageway providing communication between the second flow-providing means and the second valve, and operating fluid passageways between the operating fluid flow-providing means and trigger means and between the trigger means and cylinder, the housing being hand-held, first and second pinion gears connected to the first and second valves, respectively, and engaging the rack means, reciprocation of the piston causing movement of the first and second valves between first orientations providing flows of the first and second components and second orientations blocking flow of the first and second components.
A dispensing apparatus for plural component materials adapted to be hand-held, comprising a housing adapted to be connected with means to supply a flow of first and second components and an operating fluid and to be manipulated by hand, first and second valves carried by said housing to control the flow of said first and second components, respectively, a fluid-operated piston carried within a cylinder formed by said housing, first means operated by said piston and effecting operation of said first and second valves as said piston is moved between first and second positions by the pressure of said operating fluid, the first means including a rack, and at least one pinion gear engaging the rack and controlling the operation of the first and second valves, second means carried by said housing and adapted to mix the first and second components when flowing and to direct the mixed components from the housing, a trigger for controlling the movement of said piston, the trigger being carried by the housing for operation by hand, said trigger directing a flow of operating fluid to move the piston to said first position where said first means opens the valves to permit the first and second materials to flow through said dispenser for mixing and directed expulsion, and said second position where said first means closes the valves.
A plural component dispensing apparatus comprising means for providing flows of first and second components of a resin system reactive in the presence of a catalyst to harden rapidly, a first housing to which the first and second flow-providing means are attached, the housing including a first passageway for conveying the first component and a second passageway for conveying the second component, a valve housing for housing a first valve in communication with the first passageway and a second valve in communication with the second passageway, each of the first and second valves being movably housed in the valve housing for movement between first orientations in which the valves provide passage of the components therethrough and second orientations blocking passage of the components, the valve housing being removably attached to the first housing to provide for ready detachment of the valve housing for cleaning.
A plural component dispensing apparatus comprising means for providing flows of first and second components, first and second valves for controlling flow on the first and second components, respectively, and means for controlling the first and second valves, the control means including a trigger, means for operatively connecting the trigger to the first and second valves so that actuation of the trigger moves the first and second valves to positions allowing flow of the first and second components, means for mixing the first and second components, said mixing means including a mixing chamber, first and second orifices from which the first and second components are ejected into the chamber in first and second streams which impinge against one another at an angle as the streams exit from the first and second orifices to mix the first and second components, third means for supplying a third medium, a third orifice adjacent the first and second orifices in the mixing chamber, means in the housing for supplying the third medium to the third orifice, a third valve for controlling flow of the third medium from the third orifice, and means for controlling the third valve independently of the orientations of the first and second valves, and a nozzle for providing a stream of the mixed components from their point of inpingement out of the chamber, the control means for the first and second valves comprising first and second pinion gears coupled to the first and second valves, respectively, and rack means engaging the first and second pinion gears.
