VENTING DEVICE
A clamping assembly for venting an enclosure having openings extending from the inside of the enclosure to the outside of the enclosure, the clamping assembly having a band portion having an inside surface oriented towards the enclosure and an outside surface opposite the inside surface, the band portion having at least one hole extending therethrough from the inside surface to the outside surface of the band portion, and gas permeable and liquid impermeable venting element covering at least one hole in the band, wherein at least one hole in the band portion is at least partially aligned with an opening of the enclosure to provide a fluid path between the inside of the enclosure and the outside of the enclosure.
1 . A vented boot assembly for mounting on a shaft, the assembly comprising:
a. a boot having least one opening therein providing fluid communication between the interior of the boot and the exterior of the boot,
b. an air permeable and liquid impermeable venting element covering one or more openings, in said boot and
c. clamp having at least one opening aligned with at least one opening in the boot wherein the opening in the clamp and the opening in the boot provide a fluid path between the shaft and the exterior of said boot.
2 . The vented boot assembly of claim 1 in which said venting element comprises PTFE.
3 . The vented boot assembly of claim 1 in which said venting element is oleophobic.
4 . The vented boot assembly of claim 1 in which said venting element is attached to said clamp.
5 . A clamp for attaching a boot to a shaft, the clamp comprising:
a. a structural member for surrounding the boot and the shaft and securing the boot to the shaft, the structural member having a first surface for positioning adjacent to the boot and a second surface opposite the first surface,
b. a passageway through the structural member for providing fluid communication through the structural member, and
c. a gas permeable and liquid impermeable venting element covering the passageway.
6 . The clamp of claim 2 wherein the venting element is disposed on the interior surface of the clamp.
7 . The clamp of claim 2 in which the structural member is metallic.
8 . The clamp of claim 2 in which the structural member is polymeric.
9 . A clamping assembly for venting an enclosure having openings extending from the inside of the enclosure to the outside of the enclosure, the clamping assembly comprising:
a. rounded band portion having an inside surface oriented towards the enclosure and an outside surface opposite the inside surface, the band portion having at least one hole extending therethrough from the inside surface to the outside surface of the band portion,
b. gas permeable and liquid impermeable venting portion disposed covering at least one hole in the band
c. wherein at least one hole in the band portion is at least partially aligned with an opening of the enclosure to provide a fluid path between the inside of the enclosure and the outside of the enclosure.
