Abstract

A debris trap for use in a gas valve fitting is provided. The debris trap comprises an elongated body extending about a first axis. The elongated body forms a passage therein extending along the first axis between an inlet formed in a first end of the elongated body and at least one outlet formed in the elongated body. The at least one outlet is formed in a side wall of the elongated body to provide fluid communication with the passage about a second axis perpendicular to the first axis.

Claims (9)

1. A debris trap for a gas valve, the debris trap comprising:

a fitting body defining a first passage therethrough having a first inlet adapted to couple to the gas valve and a first outlet adapted to mate with an external gas fitting;

a seat positioned at least partially within the fitting body at the first inlet;

an elongated body positioned at least partially within the fitting body at the first outlet, the elongated body extending about a first axis, the elongated body forming a second passage therein extending along the first axis between a second inlet formed in a first end of the elongated body and at least one second outlet formed in the elongated body, the at least one second outlet formed in a side wall of the elongated body to provide fluid communication with the second passage about a second axis perpendicular to the first axis communicating the first passage with the second passage, the elongated body having a closed end distally positioned from the first end, the elongated body being a one-piece unitary body;

further comprising a flange extending radially outward from an outer periphery of the elongated body, the flange being unitarily formed with the elongated body into a single piece;

wherein an outer diameter of the elongated body and an inner diameter of the first outlet of the fitting body form a debris trapping channel therebetween;

wherein the flange is located in proximity to the first end of the elongated body and axially displaced from the at least one second outlet; and

wherein the flange includes an annular groove defined therein to facilitate trapping debris therein.

2. The debris trap of claim 1 , wherein the at least one second outlet is axially displaced from the first end along the first axis.
