## Abstract

A nozzle adapter for connecting corrugated tubing to a fog nozzle housing. The nozzle adapter comprises a channel body and a clamp, the channel body having a connector section and defining a flow channel extending through the channel body. The connector section comprises an outlet opening of the flow channel and is adapted and configured to removably connect to a piece of corrugated tubing. The clamp is operatively connected to the channel body and operable to clamp a fog nozzle housing so that an outlet end of the fog nozzle housing faces downstream toward the flow channel.

## Claims

### Claim 1

A nozzle adapter for connecting corrugated tubing to a fog nozzle housing, the nozzle adapter comprising:
a channel body, the channel body defining a flow channel that extends through the channel body, the flow channel having an inlet opening formed in the channel body and an outlet opening formed in the channel body, the flow channel having an axis, the flow channel axis extending from the inlet opening to the outlet opening in a downstream direction and from the outlet opening to the inlet opening in a upstream direction, the flow channel axis defining longitudinal directions parallel to the flow channel axis and radial directions emanating perpendicularly from the flow channel axis;
the channel body having a connector section, the outlet opening being comprised in the connector section, the connector section being adapted and configured to removably connect to a piece of corrugated tubing when an open end of the corrugated tubing is aligned with the outlet opening and the piece of corrugated tubing is pushed in the upstream direction into engagement with the connector section;
a clamp, the clamp being operatively connected to the channel body and operable to clamp a fog nozzle housing so that an outlet end of the fog nozzle housing faces downstream toward the flow channel;
the clamp comprising a plurality of clamp elements, each clamp element being connected to the channel body, each clamp element having a respective contact portion, the contact portions circumscribing a circular clamp area, at least a portion of the flow channel inlet opening facing upstream toward the clamp area, at least a first one of the clamp elements being movable to move the respective first contact portion outwardly to expand the clamp area, to permit an outlet end portion of the fog nozzle housing, the fog nozzle housing outlet end portion comprising the fog nozzle housing outlet end, to be inserted through the clamp area in the downstream direction, and to move the respective first contact portion inwardly to contract the clamp area, to clamp the fog nozzle housing outlet end portion in the clamp area between at least the first contact portion and a respective second contact portion of a second one of the clamp elements;
the clamp comprising at least one biasing member, the biasing member being operatively connected to the first clamp element to provide a clamping force to bias the first contact portion inwardly, such that, when an opening force opposing the clamping force is applied to the first clamp element, to move the first clamp element so as to move the first contact portion outwardly to expand the clamp area to receive the inserted fog nozzle housing outlet end, when the nozzle housing outlet end is inserted through the clamp area in the downstream direction, and when the opening force is removed from the first clamp element, the nozzle housing outlet end is clamped between at least the first contact portion and the second contact portion.

### Claim 2 (depends on 1)

The nozzle adapter of claim 1, further comprising the clamp being operable to clamp the fog nozzle housing so that the channel body is spaced from the fog nozzle housing by a clearance, to permit a mixture of surrounding air and fog emitted from the fog nozzle housing outlet end to flow into the flow channel.

### Claim 3 (depends on 1)

The nozzle adapter of claim 1, wherein the flow channel axis is comprised in a straight line.

### Claim 4 (depends on 1)

The nozzle adapter of claim 1 wherein the channel body is of one-piece molded construction.

### Claim 5 (depends on 1)

The nozzle adapter of claim 1 wherein the first clamp element is pivotally connected to the channel body.

### Claim 6 (depends on 5)

The nozzle adapter of claim 5 wherein the first clamp element comprises a clamp arm and a clamp grip, the clamp grip comprising the first contact portion and being pivotally connected to the clamp arm for pivotal movement about a clamp grip pivot axis, the clamp arm being pivotally connected to the channel body about a clamp arm pivot axis parallel to the clamp grip pivot axis, the clamp arm being biased about the clamp arm pivot axis so as to move the clamp grip pivot axis inwardly, so as to move the first contact portion inwardly.

### Claim 7 (depends on 1)

The nozzle adapter of claim 1, the contact portions comprising a resilient and heat resistant grip material.

### Claim 8 (depends on 1)

The nozzle adapter of claim 1, the channel body having an inlet funnel defining an inlet portion of the flow channel comprising the inlet opening, the inlet portion being tapered inwardly in the downstream direction from the inlet opening.
