Exhaust rain cap assembly with channel vane member
An exhaust rain cap assembly for covering the end of an exhaust conduit, the exhaust rain cap assembly including a channel vane member comprising a channel vane for attaching to the lid and stop member. The exhaust rain cap assembly may also include a counterbalance that interacts with a spacer, bushing or other stop member to provide for the lid to stop in a plurality of positions including a closed position, a first open position for when the engine is idling, and a second open position when the engine is in operating.
1. An exhaust rain cap assembly for use in connection with the end of an exhaust conduit, the exhaust rain cap assembly comprising:
a bracket for encircling at least part of the end of the exhaust conduit;
a cover having a top side;
a channel vane member including:
a channel vane attached to the top side of the cover;
a pivot arm rotationally attached to the bracket; and
an end;
a stop member; and
a counterbalance attached to the end of the channel vane member, the counterbalance including an inner surface having at least three segments that interact with the stop member to permit the cover to be positioned in a closed position, an intermediate open or idling position and a fully open position.
2. The exhaust rain cap assembly as claimed in claim 1 wherein the stop member includes a spacer.
3. The exhaust rain cap assembly as claimed in claim 2 wherein the stop member further includes a second stop member.
4. The exhaust rain cap assembly as claimed in claim 3 where the second stop member is a bushing.
5. The exhaust rain cap assembly as claimed in claim 1 wherein the first and second segments are obtusely angled relative to one another and the second and third segments are obtusely angled relative to one another.
6. The exhaust rain cap assembly as claimed in claim 1 wherein the at least three segments are four segments.
7. The exhaust rain cap assembly as claimed in claim 1 wherein two of the at least three segments engage the stop member to retain the cover in the intermediate open position until pressure in the exhaust conduit increases to bias the cover into the fully open position.
8. An exhaust rain cap assembly for use in connection with the end of an exhaust conduit, the exhaust rain cap assembly comprising:
a bracket for encircling at least part of the end of the exhaust conduit;
a cover having a top side;
a channel vane member including:
a channel vane attached to the top side of the cover;
a pivot arm rotationally attached to the bracket; and
an end;
a stop member; and
a counterbalance attached to the end of the channel vane member, the counterbalance including an inner surface having at least three segments that interact with the stop member to permit the cover to be positioned in at least a first position, a second position and a third position wherein the first and second segments being obtusely angled relative to one another to form a first area for engaging and retaining the stop member in the first position, the second and third segments being obtusely angled relative to one another to form a second area for engaging and retaining the stop member in the second position.
9. The exhaust rain cap assembly as claim in claim 8 which further comprises a fourth segment, wherein the third and fourth segments are angled relative to one another to form a third area for engaging and retaining the stop member in the third position.
10. The exhaust rain cap assembly as claim in claim 9 wherein the first position is a closed position, the second position is an intermediate open position and the third position is a fully open position.
