[Prior Art] A dispenser for a plurality of component ratios of a mixed material such as poly and other foams is well known. This device is traditionally a simple mechanical proportional distributor, otherwise it is a complex and cumbersome hydraulic power unit. While electric units such as those shown in U.S. Patent No. 3,196,802 have been used to scale a plurality of parts, the unit is not designed for use in such rapid setting materials that require precise control of ratios and pressures. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a proportional dispenser that is electrically and easily fabricated and easily transported and capable of accurately metering two components. For this purpose, the proportional dispenser has a variable speed control DC motor having a gearbox and a crankshaft at either end of the reciprocating piston. Such motors, gearboxes and crankshafts are well known for use in electric airless paint sprayers, such as those sold under the trademark ULTRA by the assignee of the present invention. The output of the two pumps is fed to a manifold where the pressure of each output is measured. The user sets a set point pressure (eg, 1 〇〇〇 psi) and the controller then compares the pressure of the first and second components ( -5 · 1303996 (2) typically labeled with catalyst or A Ingredients and resin or component B), and control the pressure of the two pressures relative to the set point. Today, most materials are designed for a ratio of 1:1, that is, each component has an equal number. Based on changes in viscosity and temperature, the pressure may be higher on one side or the other, even if an equal amount of each component is taken (for mixing at a spray gun or other applicator). Thus the controller continuously compares these pressures and adjusts the higher side to the set point. By continuously watching the output pressure on both sides to monitor the ratio guarantee. If a side falls below a predetermined percentage of the set point (50% in the preferred embodiment), an alarm is issued or the operation is stopped. Of course, this valve percentage can be varied. [Embodiment] The ratio of the dispenser of the present invention, which is substantially indicated by 10, is shown in Figs. 1 and 2. For this purpose, the proportional dispenser 1 has a variable speed control DC motor 12 with a gearbox 14 and a crankshaft 16 attached to either end of the reciprocating piston pump 18. Such motors, gearboxes and crankshafts are well known for use in electric airless paint sprayers, such as those sold by the assignee of the present invention under the trademark ULTRA. The output 18a of the two pumps 18 is fed to the heater 20 and thus to a manifold 22 where the pressure is measured by the pressure sensor 24 for each output. The user sets a set point pressure (e.g., 1 000 psi) and the controller 26 then compares the pressure of the two components and controls the higher pressure of the two pressures relative to the set point. The DC motor controller is of the type shown in U.S. Patent No. -6- 303, 996, the entire disclosure of which is incorporated herein by reference. Today, most materials are designed for a ratio of 1:1, that is, each component has an equal number. Based on changes in viscosity and temperature, the pressure may be higher on one side or the other, even if an equal amount of each component is taken (for mixing at a spray gun or other applicator). The controller 26 thus continuously compares these pressures and adjusts the higher side to the set point. By continuously watching the output pressure on both sides to monitor the ratio guarantee. If a side falls below a predetermined percentage of the set point (50% in the preferred embodiment), an alarm is issued or the operation is stopped. Of course, this valve percentage can be varied. By continuously watching the output pressure on both sides to monitor the ratio guarantee. If a side falls below a predetermined percentage of the set point (50% in the preferred embodiment), an alarm is issued or the operation is stopped. Various changes and modifications of the proportioning device are intended to be made without departing from the spirit and scope of the invention, as defined by the scope of the following claims.
