Abstract
A starting fluid injection system includes an in-line filter having a body and a filter element. The body defines a passageway extending between the ends of the body and a set of threads formed around the passageway intermediate the ends. The filter element includes a tubular shaft that is threadedly received in the set of threads and a filter mounted to the tubular shaft remote from the set of threads. The tubular shaft is dimensioned to create an annular chamber between the shaft and the body and the annular chamber is in fluid communication with the exterior of the filter portion.

In a starting fluid injection system of the type comprising a starting fluid canister valve, a conduit coupled to the valve, and an atomizer coupled to the conduit, the improvement comprising:
- an in-line filter mounted between the valve and the atomizer, said filter comprising a body and a filter element;
- said body comprising a first, inlet end and a second, outlet end, a passageway extending therebetween in communication with the conduit, and a set of threads around the passageway intermediate the ends;
- said filter element comprising a mounting portion and a filter portion, said mounting portion comprising a tubular shaft threadedly mounted in the set of threads, said tubular shaft dimensioned to create a chamber between the shaft and the body, said filter portion mounted to the mounting portion at a location remote from the set of threads, said chamber comprising an opening adjacent the inlet end, said chamber disposed between the threads and the inlet end.
An in-line filter comprising:
- a body comprising a first, inlet end and a second, outlet end, a passageway extending therebetween, an attachment structure at each of the ends shaped to secure the body to adjacent elements, and a set of threads around the passageway intermediate the ends;
- a filter element comprising a mounting portion and a filter portion, said mounting portion comprising a tubular shaft threadedly mounted in the set of threads, said tubular shaft dimensioned to create a chamber between the shaft and the body, said filter portion mounted to the mounting portion at a location adjacent the inlet end and remote from the set of threads, said chamber comprising an opening adjacent the inlet end, said chamber disposed between the threads and the inlet end.
An in-line filter comprising:
- a body comprising first and second ends, a passageway extending therebetween, an attachment structure at each of the ends shaped to secure the body to adjacent elements, and a set of threads around the passageway intermediate the ends;
- a filter element comprising a mounting portion and a filter portion, said mounting portion comprising a tubular shaft threadedly mounted in the set of threads, said tubular shaft dimensioned to create a chamber between the shaft and the body, said filter portion mounted to the mounting portion at a location remote from the set of threads, said chamber comprising an opening adjacent the filter portion;
- wherein the in-line filter further comprises an orifice defining element along the length of the passageway, said orifice defining element positioned such that the set of threads is disposed between the filter element and the orifice defining element along the passageway.
An in-line filter comprising:
- a body comprising first and second ends, a passageway extending therebetween, an attachment structure at each of the ends shaped to secure the body to adjacent elements, and a set of threads around the passageway intermediate the ends;
- a filter element comprising a mounting portion and a filter portion, said mounting portion comprising a tubular shaft threadedly mounted in the set of threads, said tubular shaft dimensioned to create a chamber between the shaft and the body, said filter portion mounted to the mounting portion at a location remote from the set of threads, said chamber comprising an opening adjacent the filter portion;
- wherein the mounting portion further comprises a flange extending radially outwardly from the tubular shaft adjacent the body, said opening being annular in shape and defined between the flange and the body.
In a starting fluid injection system of the type comprising a starting fluid canister valve, a conduit coupled to the valve, and an atomizer coupled to the conduit, the improvement comprising:
- an in-line filter mounted between the valve and the atomizer, said filter comprising a body and a filter element;
- said body comprising inlet and outlet ends, a passageway extending therebetween in communication with the conduit, and a set of threads around the passageway intermediate the ends;
- said filter element comprising a mounting portion and a filter portion, said mounting portion comprising a tubular shaft threadedly mounted in the set of threads, said tubular shaft dimensioned to create a particulate capturing chamber between the shaft and the body, said filter portion mounted to the mounting portion at a location remote from the set of threads, said particulate capturing chamber comprising an opening adjacent the filter portion, said particulate capturing chamber in fluid communication with the inlet end via the opening;
- wherein the particulate capturing chamber defines a vertically oriented axis, and wherein the filter portion is positioned above the particulate capturing chamber, adjacent the inlet end, said particulate capturing chamber operating to capture particulates entering the passageway at the inlet end.
