Abstract

An assembly for a fire extinguisher system includes a fire extinguisher fitting that extends into a fire extinguisher container and a fill adapter. The fitting defines a fitting bore through which a connection portion of a pressure monitoring device at least partially extends and a fitting flange that is disposed about the fitting and is disposed parallel to a flange of the pressure monitoring device. The fill adapter includes an adapter housing and an adapter shaft. The adapter housing is arranged to be disposed about the pressure monitoring device. The adapter shaft that at least partially extends through the adapter housing. The adapter shaft is arranged to engage a monitoring housing of the pressure monitoring device.

First claim

What is claimed is:

1. A fire extinguisher system, comprising:
a fire extinguisher fitting that extends into a fire extinguisher container; and
an assembly that extends into the fitting, the assembly, comprising
a pressure monitoring device having a connection portion that extends into the fitting, a monitoring housing, and a flange between the connection portion and the monitoring housing, and
a fill adapter having an adapter housing disposed around the pressure monitoring device and an adapter shaft that engages the pressure monitoring device.

2. The fire extinguisher system of claim 1 , wherein the adapter shaft includes a first portion that is within the adapter housing and a second portion that extends from the first portion and through the adapter housing.

3. The fire extinguisher system of claim 1 , wherein the fill adapter defines a fill port.

4. The fire extinguisher system of claim 3 , wherein the fitting includes a fitting bore that extends between a first fitting end and a second fitting end, the fitting bore extending into the fire extinguisher container.

5. The fire extinguisher system of claim 4 , wherein a sealing member is disposed within the fitting bore, the sealing member defining an opening.

6. The fire extinguisher system of claim 4 , wherein the fitting defines a fitting flange at the first fitting end, the fitting flange being parallel to the flange of the pressure monitoring device.

7. The fire extinguisher system of claim 6 , wherein a fill path is defined between the fitting flange, the flange, the fitting bore, and an outer surface of the connection portion.

8. The fire extinguisher system of claim 7 , wherein the fill port is fluidly connected to an internal volume of the fire extinguisher container through the fill path.
