Abstract
A coupling assembly includes a mechanical attachment to accommodate various diameter fluid passages and resists rotational forces of attaching and detaching a hose from the hose coupler. The mechanical attachment includes a shank having a shoulder defining a space with a conduit of the hose coupling assembly or with a spacer disposed in the conduit. A threaded coupler includes a projecting portion disposed adjacent to the shoulder. The threaded coupler includes a key, or a recess to mate with a key, to substantially prevent rotation of the threaded coupler with respect to the hose coupler.
Claims21
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 channel through the housing, the conduit defining an axial centerline;
- a shank disposed within the 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
- a coupler located at a second end of the housing, the coupler including a threaded portion and a projecting portion extending toward the axial centerline of the channel, wherein the projecting portion is disposed adjacent to the shoulder of the shank.
A coupling assembly comprising:
- a conduit defining a fluid channel having an upstream opening, a downstream opening, and an axial centerline, wherein fluid moves from the upstream opening and exits through the downstream opening;
- a shank including a shank shoulder, the shank being disposed within the channel;
- and
- a coupler located at the upstream opening, the coupler including a threaded portion and a projecting portion extending toward the axial centerline, wherein the projecting portion is disposed adjacent to the shoulder of the shank.
The coupling assembly of clam 19 wherein the threaded conduit includes second threads and the conduit comprises a threaded conduit and the second threads threadingly engage the threaded conduit.
