Abstract
An air drying arrangement for a commercial vehicle is provided having two or more desiccant canisters arranged in parallel on a single air dryer body. The arrangement may include a coupling device that attaches to the body and allows the two or more desiccant containing canisters to mount to the device. The arrangement may be configured to balance the flow of air to each of the desiccant containing canisters when drying air and/or when regenerating the desiccant.
Claims10
A device attaching a pair of desiccant cartridges such that air flows to the pair of desiccant cartridges in parallel, the device comprising:
- an inner chamber;
- a first fluid flow passage for communicating air to the inner chamber;
- a pair of extensions, each of the pair of extensions adapted for mounting one of the pair of desiccant cartridges;
- wherein each extension is spaced at a substantially equal distance from the inner chamber;
- and
- a second and a third fluid flow passage, each fluidly connecting the inner chamber with each of the pair of threaded extensions, compressed air flowing in substantially the same direction at substantially the same time through each of the second and third fluid passages in substantially equal amounts.
A method for increasing the air drying capacity of a commercial vehicle, the method comprising:
- fluidly communicating at least two desiccant containing canisters with a single air dryer body;
- and
- flowing compressed air to each of the at least two desiccant containing canisters in parallel, in substantially the same direction, at substantially the same time, and in substantially equal amounts to remove moisture from the compressed air.
The method of 9 wherein the mixing chamber is cooperatively defined by a first coupling component attached to the air dryer body and a second coupling component attached to the first coupling component, the at least two desiccant containing canisters being attached to the second coupling component such that the at least two desiccant containing canisters are in fluid communication with the single air dryer body.
