Dispensing assembly and method for dispensing a mixed fluid

摘要

A dispensing assembly and method for preventing a lead-lag condition between first and second fluid components forming a mixed fluid includes a nozzle and a mixer insert connected to first and second barrels respectively containing the first and second fluid components. The nozzle has a nozzle inlet that includes first and second cavity portions. The mixer insert is positioned at least partially within the nozzle inlet to collectively define respective first and second passages. The first and second passages are adapted for directing the first and second fluid components into a nozzle bore of the nozzle for forming a pre-mixed fluid according to a predetermined ratio. The nozzle is further adapted to mix the pre-mixed fluid for dispensing the mixed fluid from the nozzle.

1. A nozzle for reducing or preventing a lead-lag condition while dispensing a mixture of a first fluid component and a second fluid component, comprising;
a nozzle body having a nozzle inlet and a nozzle bore extending therethrough, the nozzle inlet including a first cavity portion adapted to receive the first fluid component and a second cavity portion adapted to receive the second fluid component, the first and second cavity portions respectively extending from the nozzle inlet to a first inner surface and a second inner surface, the first and second inner surfaces being bounded between the nozzle inlet and the nozzle bore such that the first cavity portion defines a first cavity volume and the second cavity portion defines a second cavity volume, and the first cavity volume is smaller than the second cavity volume; and a channel extending through the first inner surface to the nozzle bore that further defines the first cavity portion, wherein the first cavity portion is configured to direct the first fluid component into the nozzle bore and the second cavity portion is configured to direct the second fluid component into the nozzle bore with the first fluid component, according to a predetermined ratio between the first and second fluid components.
