Abstract

A metering system for delivering and metering two combinable and cooperatable liquids, in predetermined ratios in order to enable ultimate combining of such liquids or the fluids. The apparatus comprises a first discrete valve mechanism which is capable of receiving a first fluid from a source and a cooperating first discrete metering mechanism; a pumping mechanism for receiving the fluid from and directing fluid to this first valve mechanism. The apparatus also comprises a second discrete valve mechanism capable of receiving a second fluid from a source and an associated second discrete metering mechanism; a pumping mechanism for receiving fluid from and directing fluid to this valve mechanism. An actuating device operatively connects the first and second valve mechanisms and the first and second metering mechanisms in order to enable the first metering mechanism to pump the first fluid to and from the first valve mechanism and the second fluid to and from the second valve mechanism. The valve mechanisms are capable of metering the first and second fluids in proper predetermined amounts. The fluids may be combined at a mixing member as for example, a mixing gun.
