The present invention relates generally to desiccant bags and filters
for use in receiver/dryers or accumulator canisters of automotive
air conditioning systems. More specifically, the present invention
relates to a dual or single desiccant bag provided with a filter
section such that the desiccant bag effectively combines two separate
components, a desiccant bag and a filter, into a single article.
Accordingly, the bag is adapted to contain adsorbent material therein
to adsorb moisture, or undesirable substances, within the a/c systems
of automobiles, trucks or other motor vehicles while the filter
is adapted to keep particles, dirt, or dust from entering the orifice
in the bight of a U-bend tube where oil pickup is provided for lubrication
of the a/c system.
A desiccant feeder system comprising, a reservoir for desiccant
canisters, means for delivering the canisters through a transfer
tube to at a loading station, means for presenting the open end
of containers one at a time at the loading station, means for circulating
air at high velocity through the tubing including an adjustable
internal ring-shaped nozzle to deliver desiccant canisters from
the reservoir to the loading station, and a shuttle selectively
actuatable to discharge at least one desiccant cannister to the
containers at the loading station.
In a display device which is formed by attaching together a device
substrate and a sealing substrate, a desiccant is coated to form
a shape having a plurality of bending portions on the sealing substrate.
Furthermore, the path coated with the desiccant on the sealing substrate
is longer than conventional devices, thereby increasing a gross
surface area and thus improving moisture absorption effect.
An air dryer assembly for removing moisture and oil from a compressed
air system includes a desiccant material received in a shell for
adsorbing moisture as compressed air passes therethrough. A coalescing
element is disposed between an inlet and outlet for removing oil
aerosols from the compressed air. A check valve is disposed in parallel
with the coalescing element and forces the compressed air to pass
through the coalescing element as air flows from the inlet to the
outlet. During a purge or reverse flow, compressed air bypasses
the coalescing element and removes oil collected in the cartridge
through the inlet.
