1. A fluid delivery assembly comprising:
a housing; an outflow member disposed at a first end of the housing, the outflow member being configured to dispense fluid; a conduit located within the housing and defining a fluid channel through the housing, the conduit having an end portion positioned proximate a second end of the housing, wherein the conduit defines an axial centerline, wherein the conduit includes a first conduit cylindrical portion and a second conduit cylindrical portion, wherein a transition from the first conduit cylindrical portion to the second conduit cylindrical portion defines a conduit shoulder, and wherein the conduit includes threads; a shank disposed within the fluid channel, the shank including a first portion and a second portion, wherein a transition from the first portion to the second portion defines a shank shoulder, and wherein the shank includes threads; and a coupler located at the second end of the housing, the coupler including a threaded portion and a projecting portion extending toward the axial centerline of the fluid channel, wherein the projecting portion is disposed adjacent to the shoulder of the shank, wherein the projecting portion of the coupler is disposed within a cavity defined by the shoulder of the shank and one of the conduit and a spacer, and wherein the spacer includes threads; wherein the end portion of the conduit abuts the coupler to fix an insertion amount of the coupler within the fluid channel; wherein the housing further includes an upstream opening and a downstream opening wherein fluid is directed by the conduit from the upstream opening to exit through the downstream opening, and the projecting portion of the coupler is disposed closer to the downstream opening than the shoulder of the shank is to the downstream opening; wherein the threads of the shank threadingly engage with the threads of the spacer; and wherein the threads of the spacer threadingly engage with the threads of the conduit. |
