Dispensing assembly and method for dispensing a mixed fluid

A dispensing assembly for reducing or preventing a lead-lag condition while dispensing a mixture of a first fluid component and a second fluid component, comprising;

• a first barrel having first chamber, a second barrel having a second chamber, the first and second chambers for containing the first and second fluid components;
• a mixer insert having a first and a second mixer inlet, the first and second mixer inlets respectively in fluid communication with the first and second chamber;
• a nozzle, the nozzle including a nozzle body having a nozzle inlet and a nozzle bore extending therethrough, the nozzle inlet having a first cavity portion and a second cavity portion;
• a first passage collectively defined by the mixer insert and the first cavity portion, the first passage configured to direct a first volume of the first fluid component into the nozzle bore;
• and
• a second passage collectively defined by the mixer insert and the second cavity, the second passage configured to direct a second volume of the second fluid component into the nozzle bore,
• wherein the first and second passages are adapted for directing the first and second fluid components into the nozzle bore to form a pre-mixed fluid having a predetermined ratio of first and second fluid components, the nozzle being adapted to mix the pre-mixed fluid for dispensing a mixed fluid from the nozzle.

A method for reducing or preventing a lead-lag condition with a mixer insert while dispensing a mixture of a first fluid component and a second fluid component from a nozzle, comprising;

• forcing the first and second fluid components through the mixer insert and into respective first and second passages;
• forcing the first fluid component through the first passage along a channel within a nozzle inlet into a nozzle bore;
• forcing the second fluid component through the second passage within the nozzle inlet into the nozzle bore;
• increasing the velocity of the first fluid component for generally preventing the lead-lag condition;
• positioning the first fluid component adjacent to the second fluid component in a nozzle bore of the nozzle for forming a pre-mixed fluid;
• mixing the pre-mixed fluid into a mixed fluid;
• and
• dispensing the mixed fluid from the nozzle.
